Ground magnetic, E-mode VLF, and radiometric surveys at Phillips Mine-Camp Smith uranium prospect, Westchester and Putnam Counties, New York

Technical Report ·
OSTI ID:6793000
Pre-Cambrian uraninite in the Phillips Mine-Camp Smith area, New York, appears to be localized along the boundary between light-colored hornblende leucogneiss and dark-colored amphibole gneiss units. There it is associated with magnetite-rich and scapolite-rich layers, with hornblende pegmatites, and with the outer shell of a massive sulfide body. The close spatial association of uraninite, magnetite, and sulfides result in nearly-coincident geophysical anomalies involving high eU channel, high total magnetic field, and low VLF apparent-resistivity measurements. Exploration targets of this type may be identifiable using inexpensive one- or two-man geophysical techniques.
