Description

The Rosiclare Fault contained the richest fluorspar vein in the entire Illinois-Kentucky district. Its trend is arcuate, curving from slightly west of north to northeast. The plane is nearly vertical, with the west side downthrown 200 to 300 feet (60-90 m). Numerous other mineralized faults interconnect with the Rosiclare Fault, along the southeast side of the Rock Creek Graben.
