Fluorspar Deposits in Western Kentucky: Part 2

It has yielded from 30,000 to 40,000 tons of crude fluorspar and nearly 20,000 tons of zinc ore. Limestones, sandstones, and shales of the Meramec, Chester, and Pottsville groups of Carboniferous age crop out as relatively flat-lying beds, except near faults.

Fluorspar Deposits in Western Kentucky: Part 3

Description: Abstract: The Moore Hill fault system in the central part of the Kentucky-Illinois fluorspar field is about 26 miles long. Fluorspar has been produced from a part nearly 5 miles long, and since mining began in 1899 this system has yielded more than 300,000 tons of fluorspar. Lead and zinc sulfides commonly are found in the ore, but only rarely do they occur in sufficient quantity to be worth recovering. The productive part of the fault system was mapped and the properties and principal mines de… more
