Aerial gamma ray and magnetic survey, Fort Pierce quadrangle, Florida. Final report

Technical Report · Wed Apr 01 00:00:00 EST 1981

OSTI ID:6484718

The Fort Pierce quadrangle covers 8000 square miles of central peninsular Florida. The region contains a portion of the Peninsular Arch, where Mesozoic and Cenozoic platform deposits overlie igneous and metamorphic basement of Paleozoic or Precambrian age. Miocene and Quaternary biogenic sediments dominate the surface. Several of the formations contain phosphorite deposits that are being mined in the northwest. No uranium deposits are known, but uranium is known to exist in the phoshorites in concentrations higher than the adjacent units. A total of 33 anomalies were detected in the interpretation process. These anomalies are largey culturally induced, but a few that are associated with the strip mining for phosphorite show extremely high measured uranium values. These anomalies are considered significant, and indicate that a more detailed resource study is in order in the Florida phosphorites. Magnetic data appear to show complexities in the basement materials, and bear little resemblance to the existing structural interpretations in the region.
