Geology of the Uraniferous Bog Deposit at Pettit Ranch, Kern County, California

Primary ore controls at the Pettit Ranch deposit are: (1) waters of high uranium content, (2) a suitable collector for the uranium (peat), and (3) restricted circulation. These are important guides for prospecting. Methods or prospecting, such as structural studies aimed at checking faults for springs and depressed boggy areas, systematic water sampling, or merely ground reconnaissance of boggy areas, could be employed. The effectiveness of airborne radiometric prospecting methods is limited by the low gamma radioactivity of the bog ore.
