Report issued by the U.S. Bureau of Mines on a survey of tin deposits in California. A focus on tin deposits in Kern and San Bernardino Counties are presented. The report includes two maps.

From introduction: An autunite deposit in the SW 1/4 sec. 25, T. 10 N., R. 13 W. San Bernardino meridian, was visited by F. M. Chace on May 6 and 15, 1950. The deposit is about 100 yards west of a north-south country road and is at an altitude of approximately 2,775 feet. The autunite-bearing tuffaceous sandstone strikes N. 35-40 W. and dips 20 -25 SW. It has been traced about 40 feet along the strike at the base of the outcrop and for about 20 feet up the dip. Insufficient work was done to give an accurate idea of the size of the deposit or to determine if other autunite-bearing beds are present.

Geologic studies of the uranium deposits in the Kern River in order to evaluate the showings and to determine the mode of occurrence of uranium minerals.
