Uranium and Phosphate in the Western Part of the Bonny Lake Mine, Polk County, Florida

Description: From abstract: During the month of May 1950, the Davison Chemical Corporation, under contract with the Atomic Energy Commission, drilled 24 phosphate prospecting holes in the western part of the Bonny Lake mine, in the SW NW4 and the NW*SW4 sec. 32, T. 29 S., R. 24 E., Polk County, Fla.

The results presented in this paper are based upon a study of drill cores, drill logs, gamma-ray logs, and the chemical analyses of drill-core samples.
