Report of Investigations--KGS
The Western Kentucky Fluorspar District (WKFD), which comprises the Kentucky portion of the Illinois–Kentucky Fluorspar District, is well known for the occurrence of strategically important critical mineral resources, such as fluorite (fluorspar) and rare earth elements (REEs). Due to technological advances, demand has increased for critical minerals used in cell phones, magnets in wind turbines, batteries for electric vehicles, smart weapons, and other devices and systems. The overall objective of the Earth Mapping Resources Initiative (Earth MRI) program, directed by the U.S. Geological Survey (USGS), is to gather information that will help better understand the distribution of critical minerals in …
Heavy-Oil And Bitumen Resources Of The Western Kentucky Tar Sands, J. Richard Bowersox
Heavy-Oil And Bitumen Resources Of The Western Kentucky Tar Sands, J. Richard Bowersox
Report of Investigations--KGS
Heavy-oil and bitumen resources in western Kentucky are present in the Upper Mississippian Big Clifty and Hardinsburg Sandstones and Lower Pennsylvanian Kyrock and Bee Spring Sandstone Members of the Caseyville Formation in a belt extending from Logan County on the south to Breckinridge and Hardin Counties on the north.
Net oil-saturated intervals in the tar sands range from 2.5 to 4.7 m thick, largely in downthrown fault blocks in and bounding the Rough Creek Graben. Records from 1,500 wells, analysis of reservoir properties from 3,769 plugs from 135 coreholes, and bulk volume of hydrocarbon calculated in 139 surface samples were …
Coal Availability In Western Kentucky, Gerald A. Weisenfluh, William M. Andrews Jr., Robert E. Andrews, John K. Hiett
Coal Availability In Western Kentucky, Gerald A. Weisenfluh, William M. Andrews Jr., Robert E. Andrews, John K. Hiett
Report of Investigations--KGS
Fourteen quadrangles in five separate areas of the Western Kentucky Coal Field were studied to determine what factors affect the availability of coal for mining. Each study area consisted of at least two adjacent 7.5-minute quadrangles in order to account for the geologic variability across broad distances in western Kentucky, and determine how this variability affects availability. Areas both north and south of the Rough Creek Fault System were selected to measure the effect of different geologic, structural, and overburden settings on coal availability. The study emphasized the coals occurring stratigraphically between the Springfield and the Baker.
About 90 percent …
