Critical Mineral Potential of Mississippi Valley-Type and Phosphate Deposits in Central Kentucky

Grants and Contracts Details

Description

The Ordovician Lexington Limestone contains up to 10% P2O5 within the matrix of the limestone in the form of cryptocrystalline apatite. Rare earth elements are known to be associated with marine phosphates; however, Ordovician phosphates and their regolith in Central Kentucky have not yet been assessed for their REE potential. In addition to the phosphates, the Central Kentucky Mineral District is known to host over 200 vein deposits of barite, fluorite, galena, and sphalerite in Ordovician carbonates. The critical mineral potential of these MVT deposits/occurrences in the area has not yet been assessed. The currently ongoing geophysical survey covering this area will provide a unique insight into the structural control over the MVT mineralization and its relation to deep crust structures.
