Distribution and Origin of Phosphate in the Land-Pebble Phosphate District of Florida

Description: From abstract: The land-pebble phosphate district of Florida is a part of the Gulf Coastal Plain. The geologic formations cropping out in the district are the Miocene Hawthorn, Pliocene Bone Valley, and Pleistocene terrace sands. The Bone Valley formation consists of a lower strongly phosphatic unit and an upper less phosphatic unit. This paper is concerned principally with the lower unit, which contains the bulk of the minable phosphate deposits of the district.

Airborne Radioactivity Surveys for Phosphate in Florida

Description: Introduction: Deposits of phosphate in Florida, located beyond the limits of known producing areas, have been reported by prospectors and mining companies. Much of the information has been based upon prospecting and exploration which was undertaken many years ago and as a result the published data relating to the occurrence of these deposits are fragmentary, and few details relating to specific locations and extent are available.

Summary of Work on the Mineralogy and Petrography of Southeast Phosphates Through April 1952

Description: From abstract: "In this report the mineralogy and uranium contents of southeast phosphates are discussed with reference to the lithologic units of the Hawthorn and Bone Valley formations and to waste slimes. In addition, the immediate problem of sampling leached-zone rock for process development studies is discussed and plans for future work (fiscal 1953) are presented."
