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."

Report presenting the results of one part of an investigation of the regional geology of central Florida.

From Abstract: "The mineral constituents of churn drill cuttings from a well through the Bone Valley formation and into the Hawthorn formation were determined. The weight percent of each mineral is given, as well as a description of the samples and the methods used."

The following report presents the results of part of a geologic study of the phosphate deposits in central Florida. The purpose of the investigative research done in Florida is to determine the geologic history of the phosphate deposits and associated sediments, in order that the distribution of phosphate and uranium will be more clearly understood.

Discussing the stratigraphy of middle tertiary rocks in parts of West-Central Florida

Report discussing information on the aluminum phosphate zone of the Peace River area. At the time of the report, the first plant to treat aluminum phosphate was probably to be located in this area. Information on the geology of the area, weathering/erosion, mineralogy, occurrence and distribution of aluminum, chemical relations and variations of aluminum phosphate, relation of geologic features, mining plans, and tonnage/grade of the zone are included.

Report describing the geology of the land-pebble phosphate district on the Gulf Coastal Plain of Florida. This district is mapped out and the formation of land-pebble phosphate deposits is shown.

Report discussing the distribution, composition, and origin of the phosphate deposits in the land-pebble district in the Gulf Coastal Plain of Florida.

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.

Report discussing the results of geologic drilling of the land-pebble phosphate district in Florida. Specifically, the general geology, stratigraphy, mineralogy, chemistry, weathering, and economic geology are discussed.

From abstract: Investigations of the land-pebble phosphate deposits of Florida by the Geological Survey began in November 1947. This report presents the computation of reserves of phosphate rock in the northern part of the district.

From abstract: "This report is a survey of present and potential production of monazite from part of the Maryland-Florida section of the Atlantic Coastal Plain."

The following report is based mainly on information obtained from lithologic and gamma-ray logs of drill holes in the Lakeland Highlands area and Clark James-South Ridgewood.

The following documents are three maps on the stratigraphy between Hernando and Polk Counties, Florida. These maps are in relation to document USGS Bulletin 1074, "Stratigraphy of the Area Between Hernando and Hardee Counties, Florida".

"This report, one of four on the peripheral areas, describes Cenozoic rocks on the northern and eastern edges of the land-pebble phosphate district, including part of the hard rock phosphate belt, Figure 1 and Plate 1 show the area studied."

Report discussing a study of the formations on the borders of the land-pebble phosphate district to place previously done stratigraphic and economic studies of the district into a larger geologic setting.

Report discussing airborne radioactivity surveys, aimed at finding uraniferous phosphate deposits, in ten areas of Florida. A subsequent ground investigation of two radioactivity anomalies out of eight was conducted. Information on radioactivity measurements for each area is given as well as conclusions.

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.

Report discussing studies of millisite and pseudowavellite, which were "locally abundant in the leached zone of the highly phosphatic Bone Valley formation in west-central Florida." Studies include optical determinations and x-ray studies.

The following document contains two reports providing results from reconnaissance missions in Florida. These missions tested the radioactivity in Florida sands and the radioactivity in phosphates and rocks found in Florida.

Report discussing a geological examination of an area in Polk County, Florida with leached zones containing uranium. The objective of the study was to determine the advisability of making plans for stockpiling the leached zone material in this area.
