Kentucky Surficial Geologic Map Compilation Database (Version 1), Matthew Massey
Kentucky Surficial Geologic Map Compilation Database (Version 1), Matthew Massey
Research Data--KGS
The Kentucky Geological Survey (KGS), a state-supported independent research center within the University of Kentucky, is committed to providing accurate and unbiased geologic information on natural resources, environmental issues, and natural hazards in Kentucky. While Kentucky boasts complete coverage by 1:24,000-scale geologic bedrock maps, surficial materials have been largely overlooked, except in regions with thick deposits obscuring the bedrock. Given the increasing trends in economic development and urbanization, detailed surficial geologic mapping has become crucial for supporting geotechnical planning, environmental management, and hazard assessment. In response, KGS has prioritized new, detailed surficial geologic mapping since 2004, specifically targeting areas anticipated …
Joint Map Of Hardin County, Kentucky, Steven L. Martin, Emily Morris
Joint Map Of Hardin County, Kentucky, Steven L. Martin, Emily Morris
Map and Chart--KGS
New field mapping of joints with previously published joint and fault locations. This fracture map can be used as a critical data source for hydrological, karst or geotechnical applications. Joint orientations were measured in 2009, 2022 and 2023, and are combined with joint and fault locations for Hardin County, Kentucky from 1:24,000-scale USGS geologic quadrangle maps that were published from 1962 to 1977. The geologic quadrangle maps for the county were digitized from 2002 to 2007.
The geology of Hardin County consists of Upper Devonian New Albany Shale overlain by Lower to Upper Mississippian-age sequences of limestone, dolomite, sandstone and …

Earth Mri Western Kentucky Fluorspar District 3d Geological Modeling, Devan M. Robinson, Anna Pearson, John B. Hickman, Georgina Lukoczki, William Morton Andrews Jr.
Research Data--KGS
The Illinois–Kentucky Fluorspar District (IKFD) three-dimensional (3D) geological data model plays a critical role in the EarthMRI IKFD project, which aims to utilize the vast and detailed geologic maps and datasets that the Kentucky and Illinois state geological surveys possess to develop a Geographic Information System (GIS)-based 3D geological framework model for the district. The model serves as a framework in which to view the subsurface geological and geochemical data, and to better comprehend the structural and other geologic processes acting on the region as they relate to the locations of critical minerals. The development of the model will also …
Kgs Joint Data, Steven L. Martin
Kgs Joint Data, Steven L. Martin
Research Data--KGS
Joint orientation measurements collected by KGS personnel at rock exposures from 2009 to 2024. New joint data was collected using a Brunton compass. This data set is a compilation of joints measured by Steve Martin. There are three worksheets related to data structure. The joint location and joint measurement worksheets show a 1-to-many relationship. The 1to1 worksheet shows a 1-to-1 relationship between joint locations and measurements.
Version 2 uploaded December 2024, adding new data to existing set.
Dvgq Joint Data, Steven L. Martin
Dvgq Joint Data, Steven L. Martin
Research Data--KGS
A compilation of digitally vectorized joint data from the U.S. Geological Survey geologic quadrangle maps. Joint data was collected by USGS and KGS geologists using a compass during geologic mapping of the 7.5-minute quadrangle. Field notes of mappers are not available, therefore the orientation of joints was determined by a script written by KGS personnel during the digitization process.
Surficial Geologic Map Of The Flaherty 7.5-Minute Quadrangle, Kentucky, Ann Hislop, Matthew Massey, Maxwell L. Hammond Iii, Antonia E. Bottoms, Michele Mchugh, Emily Morris
Surficial Geologic Map Of The Flaherty 7.5-Minute Quadrangle, Kentucky, Ann Hislop, Matthew Massey, Maxwell L. Hammond Iii, Antonia E. Bottoms, Michele Mchugh, Emily Morris
Contract Reports--KGS
The Flaherty 7.5-minute quadrangle is located southwest of Louisville and northwest of Elizabethtown along the boundary between Hardin and Meade Counties. The quadrangle includes mostly the Pennyroyal region of the Mississippian Plateau and also smaller areas of the Mammoth Cave plateau and the highly dissected Dripping Springs escarpment in the western half of the map area (McDowell, 1986). Topography is mostly characterized by pervasive sinkhole development in a lower elevation and low-relief plain, and high-relief plateaus, ridges, and knobs of the Dripping Springs escarpment scattered along the west side of the quadrangle. Swadley (1963) mapped the bedrock geology of the …
A Methodology For The Creation Of Volcanic Gas Hazard Maps Using Satellite-Derived Sulfur Dioxide, Sanna J. Mairet
A Methodology For The Creation Of Volcanic Gas Hazard Maps Using Satellite-Derived Sulfur Dioxide, Sanna J. Mairet
Dissertations, Master's Theses and Master's Reports
Sulfur dioxide (SO2) gas has been shown to be detrimental to human and environmental health and is emitted continuously from anthropogenic and volcanic sources. Sulfur dioxide is the main target gas used for the detection of hazardous volcanic plumes due to its ease of detection by satellite sensors. However, quantitative information on potential ground-level exposure to volcanic SO2 (i.e., a volcanic gas ‘hazard map’) is currently unavailable for the vast majority of active volcanoes. Utilizing sulfur dioxide vertical column densities retrieved from the Ozone Monitoring Instrument on NASA’s Aura satellite, Gridded Population of the World v.4, planetary …
Spatial Feedback As A Mechanism To Improve Topographic Map Literacy Using The Augmented Reality Sandbox, Justin Wayne Moore
Spatial Feedback As A Mechanism To Improve Topographic Map Literacy Using The Augmented Reality Sandbox, Justin Wayne Moore
Graduate Research Theses & Dissertations
Topographic maps represent three-dimensional (3D) terrain using a system of two-dimensional (2D) symbols. To facilitate students’ understanding of topographic maps, the Augmented Reality (AR) Sandbox reads the elevation of actual sand and projects elevation information onto the sand’s surface (e.g., contour lines). Although over 600 institutions have built AR Sandboxes to help people interpret topographic maps, classroom studies using the AR Sandbox have not found significant gains on topographic map assessments. The present study is a 22 design testing the affordances of the AR Sandbox in a one on one, laboratory setting. In the first level of the study, participants …
Paterae On Io: Geologic Mapping Of Tupan Patera And Experimental Models, Megan Carolee Decker
Paterae On Io: Geologic Mapping Of Tupan Patera And Experimental Models, Megan Carolee Decker
Theses and Dissertations
Paterae cover approximately 2% of the surface of Io, Jupiter’s volcanically active moon. To understand the formation of these volcano-tectonic depressions we created a geologic map of a key region and compared this map with experimental models for Io paterae. Our mapping region is Tupan Patera, a patera that has experienced recent activity and is a detected hot spot. We identified four primary types of geologic materials: plains, patera floors, flows, and diffuse deposits. We constructed an experimental model to test previous suggestions that paterae may form as volatiles in the silicate crust are vaporized by rising magma, creating instability, …

Preliminary Geologic Map Of The Nephi 30' By 60' Quadrangle, Carbon, Emery, Juab, Sanpete, Utah, And Wasatch Counties, Utah, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
The U.S. Geological Survey is engaged in a program of field studies designed to present the geologic framework of the United States on easily read topographic maps. The maps selected as a base for these geologic data are part of the Army Map Service (AMS) series of 1° by 2° quadrangles at a scale of 1:250,000. The Price, Utah AMS 1:250,000 quadrangle is one of these maps (fig.1). For certain areas, however, chiefly those sectors of the country involved in the Geological Survey's coal exploration program, the geologic data are being compiled on newly developed base maps at a scale …
