Description
The deposits of critical minerals within the Kentucky-Tennessee Mineral District (KTMD) are hosted within the Late Cambrian to Early Ordovician carbonate rocks of the Knox Group. To aid in critical mineral assessments of the region, this research project produced a map (digital GIS dataset) of the subsurface structure of the top of the Knox Group: the Knox Unconformity surface. All the input data is from oil/gas well records and exploratory mineral core records because these rocks are not exposed within the study area. Well and core records for the KTMD were acquired from the state surveys of Tennessee and Kentucky (344 points), and these were supplemented with additional regional stratigraphic top elevations from the State Geological Survey records of Missouri, Illinois, Indiana, Ohio, and West Virginia (1,034 points). Along with the GIS files (see screenshot, below), a summary table of the data points used to produce this map are included as an appendix in this report.
