  1. Geophysics, Realism, and Industry: How Commercial Interests Shaped Geophysical Conceptions, 1900-1960.Aitor Anduaga - 2015 - Oxford University Press UK.
    Did industry and commerce affect the concepts, values and epistemic foundations of different sciences? If so, how and to what extent? This book suggests that the most significant influence of industry on science in the two case studies treated here had to do with the issue of realism. However, what led physicists and engineers to adopt realist attitudes? This book suggests that a new kind of realism --a realism of social and cultural origins- is the answer. The book has two (...)

    Geophysical Basin Modeling: Effective Stress, Temperature, and Pore Pressure Uncertainty.Giuseppe De Prisco, David Thanoon, Ran Bachrach, Ivar Brevik, Stephen A. Clark, Maarten P. Corver, Randolph E. F. Pepper, Thomas Hantschel, Hans Kristian Helgesen, Konstantin Osypov & Olav K. Leirfall - 2015 - Interpretation: SEG 3 (3):SZ27-SZ39.
    Seismic interpretation is a complex process, in which many data types are considered and integrated to create a structural and/or stratigraphic model. In many cases, interpreters rely only on a seismic image or its attributes obtained after data processing and migration. Traditionally, interpretation was started after seismic imaging with little feedback to the seismic imaging process. However, modern depth imaging and tomography require integrating geologic concepts and constraints into the imaging process. Interaction between an interpreter, earth-model builder, and depth imager (...)

    Geophysical Properties of an Epithermal Au-Ag Deposit in British Columbia, Canada.Bahman Abbassi, Li Zhen Cheng, Jeremy P. Richards, Juliane Hübert, Jean M. Legault, Mark Rebagliati & Ken Witherly - 2018 - Interpretation: SEG 6 (4):T907-T918.
    The Newton Au-Ag deposit is an intermediate sulfidation state epithermal system in British Columbia, Canada. Multiple types of geophysical data are interpreted and evaluated with drillcore petrophysical, geochemical, and geologic observations to better understand the geophysical signature of the Newton epithermal system. Airborne [Formula: see text]-ray data sets indicate elevated emission counts of K, eTh, and eU over the Newton epithermal system, which are caused by hydrothermal alteration. Drillcore [Formula: see text]-ray measurements also indicate high potassium concentrations related to the (...)

    3D Geophysical Modeling of the Alberton-Mathinna Section of the “Main Slide,” Northeast Tasmania.Daniel Bombardieri, Mark Duffett, Andrew McNeill, Mike Vicary & Rod Paterson - 2020 - Interpretation 8 (3):T525-T540.
    We have developed a high-resolution 3D model of the Alberton-Mathinna section of the “Main Slide,” northeast Tasmania. This geological model expresses a new synthesis based on mapping and structural interpretation on multiple cross sections. We have refined this model by 3D geophysical inversion constrained by gravity and magnetic survey data coupled with drilling and rock physical property databases. Our modeling incorporates statistically generated sensitivity characterization metrics into 3D model products that map confidence in the geometry of geological units at depth. (...)

    Machine Learning for Geophysical Characterization of Brittleness: Tuscaloosa Marine Shale Case Study.Mark Mlella, Ming Ma, Rui Zhang & Mehdi Mokhtari - 2020 - Interpretation 8 (3):T589-T597.
    Brittleness is one of the most important reservoir properties for unconventional reservoir exploration and production. Better knowledge about the brittleness distribution can help to optimize the hydraulic fracturing operation and lower costs. However, there are very few reliable and effective physical models to predict the spatial distribution of brittleness. We have developed a machine learning-based method to predict subsurface brittleness by using multidiscipline data sets, such as seismic attributes, rock physics, and petrophysics information, which allows us to implement the prediction (...)

    Qualitative Geophysical Interpretation of the Sudbury Structure.Oladele Olaniyan, Richard S. Smith & Bill Morris - 2013 - Interpretation: SEG 1 (1):T25-T43.
    The Sudbury Structure is one of the most studied geologic structures in the world due to its enigmatic nature and mineral wealth. The available geologic work from the literature and mining industry operations accumulated for more than a century was recently assessed and compiled into a bedrock geologic map. Most regional geophysical investigations of the Sudbury Structure have been quantitative — modeling and depth estimation without a clear definition of surface control. Airborne total magnetic intensity data over the Sudbury Structure (...)

  8. Geophysical Imaging of Silurian Carbonates by Use of Ground and Airborne Electromagnetic and Radiometric Methods on the Island of Gotland, Sweden.Lena Persson & Mikael Erlström - 2015 - Interpretation: SEG 3 (3):SY1-SY11.
    The island of Gotland in the Baltic Sea exhibits rock types dominated by limestone and marlstone, deposited in a Silurian carbonate platform environment. The strata are extensively exposed in outcrops, quarries, and coastal cliff sections. Low-lying marlstone-dominated areas are separated by highs dominated by limestone. The surface bedrock is well known, but the subsurface composition down to a 100-m depth has, until recent deployment of modern geophysical measurements, been largely unknown. Our geophysical surveys and methods were performed with the aim (...)

    Inversion of Airborne Geophysics Over the DO-27/DO-18 Kimberlites — Part 3: Induced Polarization.Seogi Kang, Dominique Fournier & Douglas W. Oldenburg - 2017 - Interpretation: SEG 5 (3):T327-T340.
    The geologically distinct DO-27 and DO-18 kimberlites, often called the Tli Kwi Cho kimberlites, have been used as a testbed for airborne geophysical methods applied to kimberlite exploration. This paper focuses on extracting chargeability information from time-domain electromagnetic data. Three different TEM surveys, having similar coincident-loop geometry, have been carried out over TKC. Each records negative transients over the main kimberlite units and this is a signature of induced polarization effects. By applying a TEM-IP inversion workflow to a versatile time (...)

    Geophysical Signature of the Victoria Property, Vectoring Toward Deep Mineralization in the Sudbury Basin.Bill Spicer - 2016 - Interpretation: SEG 4 (3):T281-T290.
    Exploration throughout KGHM International’s Victoria property in Sudbury, Ontario, occurred over an approximate 10-year period and resulted in the discovery of the Victoria Deposit. A variety of geophysical techniques were used with varying results to detect Cu-Ni-PGE-rich ore bodies at depth. Near-surface methods supplemented traditional mapping and geologic interpretation techniques to gain an understanding of property-scale depositional environments. The use of 3C borehole EM surveying facilitated the transition from a broad exploration program, which was based on surface geophysical signatures and (...)

    Inversion of Airborne Geophysics Over the DO-27/DO-18 Kimberlites — Part 1: Potential Fields.Sarah G. R. Devriese, Kristofer Davis & Douglas W. Oldenburg - 2017 - Interpretation: SEG 5 (3):T299-T311.
    The Tli Kwi Cho kimberlite complex contains two pipes, called DO-27 and DO-18, which were discovered during the Canadian diamond exploration rush in the 1990s. The complex has been used as a testbed for ground and airborne geophysics, and an abundance of data currently exist over the area. We have evaluated the historical and geologic background of the complex, the physical properties of interest for kimberlite exploration, and the geophysical surveys. We have carried out 3D inversion and joint interpretation (...)

    Inversion of Airborne Geophysics Over the DO-27/DO-18 Kimberlites — Part 2: Electromagnetics.Dominique Fournier, Seogi Kang, Michael S. McMillan & Douglas W. Oldenburg - 2017 - Interpretation: SEG 5 (3):T313-T325.
    We focus on the task of finding a 3D conductivity structure for the DO-18 and DO-27 kimberlites, historically known as the Tli Kwi Cho kimberlite complex in the Northwest Territories, Canada. Two airborne electromagnetic surveys are analyzed: a frequency-domain DIGHEM and a time-domain VTEM survey. Airborne time-domain data at TKC are particularly challenging because of the negative values that exist even at the earliest time channels. Heretofore, such data have not been inverted in three dimensions. In our analysis, we start (...)

    Geophysical Methods Used in the Discovery of the Kitumba Iron Oxide Copper Gold Deposit.Thomas R. H. Woolrych, Asbjorn N. Christensen, Darcy L. McGill & Tom Whiting - 2015 - Interpretation: SEG 3 (2):SL15-SL25.
    A range of geophysical techniques has been used at various stages of the discovery and delineation of the Kitumba deposit in Central Zambia. Early era magnetics, geologic mapping, artisanal Cu plays, and the application of an iron oxide copper gold exploration model led explorers to the area in the 1990s. An airborne gravity gradiometer survey was flown in 2004, and it highlighted key regional elements considered to be prerequisite for prospective IOCG mineralization. The AGG survey accurately delineated the spatial extents (...)

    Geophysical Expression of a Buried Niobium and Rare Earth Element Deposit: The Elk Creek Carbonatite, Nebraska, USA.Benjamin J. Drenth - 2014 - Interpretation: SEG 2 (4):SJ23-SJ33.
    The lower Paleozoic Elk Creek carbonatite is a 6–8-km-diameter intrusive complex buried under 200 m of sedimentary rocks in southeastern Nebraska. It hosts the largest known niobium deposit in the U.S. and a rare earth element deposit. The carbonatite is composed of several lithologies, the relations of which are poorly understood. Niobium mineralization is most enriched within a magnetite beforsite unit, and REE oxides are most concentrated in a barite beforsite unit. The carbonatite intrudes Proterozoic country rocks. Efforts to explore (...)

    Integrated Geophysical Analysis Provides an Alternate Interpretation of the Northern Margin of the North American Midcontinent Rift System, Central Lake Superior.V. J. S. Grauch, Eric D. Anderson, Samuel J. Heller, Esther K. Stewart & Laurel G. Woodruff - 2020 - Interpretation 8 (4):SS63-SS85.
    The Midcontinent Rift System is a 1.1 Ga sequence of voluminous basaltic eruptions and multiple intrusions followed by widespread sedimentation that extends across the Midcontinent and northern Great Lakes region of North America. Previous workers have commonly used seismic-reflection data to demonstrate that the northern rift margin in central Lake Superior developed as a normal growth fault that was structurally inverted to a reverse fault during a compressional event after rifting had ended. A prominent, curvilinear aeromagnetic anomaly that extends from (...)

    Rock, Life, Fire: Speculative Geophysics and the Anthropocene.Nigel Clark - 2012 - Oxford Literary Review 34 (2):259-276.
    If origins are as complex and perturbing as Derrida suggests, then we might ask of the current anthropic environmental predicament: what kind of planet is it that gives birth to a creature capable of doing such things? Biological life may be at its liveliest along the earth's sutures and fault-lines. But so too is fire. If humans are a fire species, then this is a fire planet. From the point of view of a ‘speculative geophysics’, our combustive habits may (...)

    Geophysical Characterization of Karst Landscapes in Kentucky as Modern Analogs for Paleokarst Reservoirs.Michael T. May & Thomas B. Brackman - 2014 - Interpretation: SEG 2 (3):SF51-SF63.
    Subsurface interpretation of paleokarst reservoirs is greatly aided by 3D seismic and other modern modeling tools and the inherent complexity of productive reservoirs requires an understanding of reservoir heterogeneities and compartmentalization. Such complexity also requires a review of karst processes and development, which can be beneficially captured via geophysical characterization of near-surface karst landscape features that certainly equate to our better understanding of high-side oil productive areas. Both electrical resistivity tomography and refraction microtremor geophysical surveys at the Green River Preserve (...)

    Geophysical Basin Modeling: Methodology and Application in Deepwater Gulf of Mexico.Teresa Szydlik, Hans Kristian Helgesen, Ivar Brevik, Giuseppe De Prisco, Stephen Anthony Clark, Olav Kvamme Leirfall, Kenneth Duffaut, Christopher Stadtler & Mike Cogan - 2015 - Interpretation: SEG 3 (3):SZ49-SZ58.
    A truly integrated velocity model building method has been developed and applied for seismic imaging. Geophysical basin modeling is designed to mitigate seismic data limitations and constrains the velocity model building by taking advantage of information provided by geologic and geophysical input. The information from geologic concepts and understanding is quantified using basin model simulations to model primary control fields for rock properties, temperature, and effective stress. Transformation of the basin model fields to velocity is made by universally calibrated rock (...)

    Geophysical Interpretation of U, Th, and Rare Earth Element Mineralization of the Bokan Mountain Peralkaline Granite Complex, Prince of Wales Island, Southeast Alaska.Anne E. McCafferty, Douglas B. Stoeser & Bradley S. Van Gosen - 2014 - Interpretation: SEG 2 (4):SJ47-SJ63.
    A prospectivity map for rare earth element mineralization at the Bokan Mountain peralkaline granite complex, Prince of Wales Island, southeastern Alaska, was calculated from high-resolution airborne gamma-ray data. The map displays areas with similar radioelement concentrations as those over the Dotson REE-vein-dike system, which is characterized by moderately high %K, eU, and eTh. Gamma-ray concentrations of rocks that share a similar range as those over the Dotson zone are inferred to locate high concentrations of REE-bearing minerals. An approximately 1300-m-long prospective (...)

    Underdetermination in Geophysics.Teru Miyake - unknown
    This paper examines the epistemological implications of a particular underdetermination problem from geophysics, with an emphasis on understanding how the scientists themselves tried to deal with the problem. The problem is from the highly influential work of the geophysicists Backus and Gilbert in the late 60’s, who were trying to determine the internal structure of the Earth using seismic waves. I find that actual underdetermination problems can be vastly complex, with different sources of underdetermination having different epistemological implications. A (...)

    The Assembly of Geophysics: Scientific Disciplines as Frameworks of Consensus.Gregory A. Good - 2000 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 31 (3):259-292.
    What makes any investigative field a scientific discipline? This article argues that disciplines are ever-changing frameworks within which scientific activity is organised. Moreover, disciplinarity is not a yes or no proposition: scientific activities may achieve degrees of identity development. Degree of consensus is the key, and consensus on many questions (conceptual, methodological, institutional, and social) varies among sciences. Lastly, disciplinary development is non-teleological. Disciplines pass through no regular stages on their way from immature to mature status, designations articulated within the (...)

    Integrated Geologic, Geophysical, and Petrophysical Data to Construct Full Field Geologic Model of Cambrian-Ordovician and Upper Cretaceous Reservoir Formations, Central Western Sirte Basin, Libya.Abdalla A. Abdelnabi, Yousf Abushalah, Kelly H. Liu & Stephen S. Gao - 2019 - Interpretation: SEG 7 (1):T21-T37.
    The Cambrian-Ordovician and Upper Cretaceous formations, which are the main oil-producing formations in the central Sirte Basin, are structurally complex. The lateral and vertical heterogeneity of the reservoir formations is not well-understood, which negatively affects the performance of the reservoirs. We constructed efficient full-field static models that incorporate the lateral and vertical variation of those reservoir formations by integrating geologic and geophysical data. We determined lithology and reservoir properties by selecting appropriate petrophysical techniques that suit the available well data and (...)

    The [Formula: see text] Léogâne fan delta in southwestern Haiti borders the epicentral region of the devastating magnitude 7.0 Haiti earthquake of 12 January 2010. The flat plain of the Léogâne area experienced some of the worst shaking, destruction of buildings, and loss of life caused by the Haiti earthquake. This intense shaking was attributed by previous workers to either activation of a blind thrust fault some 4 km beneath the Léogâne fan delta or to strike-slip motion along a shallow, (...)

    Geological and Geophysical Expression of a Primary Salt Weld: An Example From the Santos Basin, Brazil.Christopher A.-L. Jackson, Clara R. Rodriguez, Atle Rotevatn & Rebecca E. Bell - 2014 - Interpretation: SEG 2 (4):SM77-SM89.
    Primary salt welds form at the base of minibasins in response to complete evacuation of autochthonous salt. Analytical and numerical models suggest it is difficult to completely remove salt from a weld by viscous flow alone, which is especially true in multilayered evaporites, within which flow is likely heterogeneous due to lithologically controlled viscosity variations. Welds are important in the hydrocarbon industry because they may provide a hydrodynamic seal and trap hydrocarbons, or may allow transmission of fluids from source to (...)

    Near-Surface Geophysical Surveys at the Duport Gold Deposit, Ontario, Canada: Relating Airborne Responses to Small-Scale Geologic Features.Ian J. Ferguson, Jeffrey B. Young, Becky J. Cook, Ashley B. C. Krakowka & Cassandra Tycholiz - 2016 - Interpretation: SEG 4 (3):SH39-SH60.
    Near-surface geophysical measurements using magnetometer, magnetic susceptibility, terrain conductivity, and time-domain electromagnetic instruments were made at the shear-hosted Duport gold deposit on Cameron Island in Shoal Lake, western Ontario, Canada, to help relate airborne total magnetic intensity and helicopter electromagnetic survey data to small-scale geologic features. The magnetic airborne response provides a weak indication of a narrow anomaly within the Duport deformation zone, and the airborne electromagnetic response provides an indication of enhanced conductivity in the northwest of Cameron Island.

    Pitfalls in Near-Surface Geophysical Interpretation: Challenging Paradigms and Misconceptions.David C. Nobes & Estella Atekwana - 2018 - Interpretation 6 (4):SL1-SL9.
    Too often, ideas become so well-established that they take on the roles of paradigms, and challenging those paradigms can be difficult, even if they are flawed. Similarly, misconceptions can take root and become firmly entrenched and again are difficult to dislodge. Both of these situations are fundamentally unscientific. Science makes progress when established theories are shown to be incorrect or at least incomplete. To do that, we have to let the data that we collect tell their stories. We should not (...)

    Modeling for Geophysical Monitoring of Multiple Phase Saturation of Rocks: Applications to CO2 Sequestration.Stephen Brown - 2014 - Interpretation: SEG 2 (2):SC47-SC60.
    A numerical study of measured petrophysical properties was used to develop and demonstrate a workflow for monitoring [Formula: see text] sequestration in a subsurface reservoir. Amplitude versus offset attributes can be sensitive discriminators for [Formula: see text] presence. The sensitivity of AVO attributes to [Formula: see text] saturation increased when an upscaling scheme that propagated the effects of small-scale heterogeneities was used. A global sensitivity analysis was then performed to study the importance of various rock properties that would be used (...)

    An Integrated High-Resolution Geophysical and Geologic Visualization of a Lake Bonneville Shoreline Deposit.Katelynn M. Smith, John H. McBride, Stephen T. Nelson, R. William Keach, Samuel M. Hudson, David G. Tingey, Kevin A. Rey & Gregory T. Carling - 2019 - Interpretation 7 (2):T265-T282.
    Pilot Valley, located in the eastern Basin and Range, Western Utah, USA, contains numerous shorelines and depositional remnants of Late Pleistocene Lake Bonneville. These remnants present excellent ground-penetrating radar targets due to their coherent stratification, low-clay, low-salinity, and low moisture content. Three-dimensional GPR imaging can resolve fine-scale stratigraphy of these deposits down to a few centimeters, and when combined with detailed outcrop characterization, it provides an in-depth look at the architecture of these deposits. On the western side of Pilot Valley, (...)

    Regional 3D Geophysical Investigation of the Sudbury Structure.Oladele Olaniyan, Richard S. Smith & Bruno Lafrance - 2015 - Interpretation: SEG 3 (2):SL63-SL81.
    The 3D geologic and structural setting of the Sudbury Structure was predicted by an integration of surface and subsurface geologic data with 2.5D modeling of high-resolution airborne magnetic and gravity data using 3D GeoModeller software. Unlike other CAD-based 3D software, GeoModeller uses the field interpolator method, whereby contacts of rock units are assumed to be equipotential surfaces, whereas orientation data determine the gradient and direction of the surfaces. Contacts and orientation variables are cokriged to generate 3D continuous surfaces for each (...)

    Kamma, Social Collapse or Geophysics? Interpretations of Suffering Among Sri Lankan Buddhists in the Immediate Aftermath of the 2004 Asian Tsunami.Kate Crosby - 2008 - Contemporary Buddhism 9 (1):53-76.
    In the immediate aftermath of the 2004 Asian tsunami, those affected struggled to come to terms with the scale of the disaster. This article documents the initial response in religious terms to the calamity by Buddhists in Sri Lanka. It looks at the interpretations they proposed for the causes of such suffering.1 The account given here is based mainly on conversations and fieldwork conducted in Sri Lanka within the first fortnight after the tsunami.2 The places, temples and organisations I visited (...)
