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.
