Abstract
The principal talc deposits in California are in a 200-mile belt paralleling the state's eastern border. The southernmost deposits represent selective alteration of early pre-Cambrian (?) carbonate strata, and are associated with granitic rocks. Deposits in the Death Valley area are at or near contacts between late pre-Cambrian carbonate rocks and diabase sills. Those in the Inyo Range area are chiefly alterations of Paleozoic carbonate rocks and silica rocks. Most of the state's talc output is used in ceramics.

© 1950 American Institute of Mining, Metallurgical, and Petroleum Engineers. The current studies of California's talc resources have proceeded at the instigation and under the helpful guidance of Dr. Olaf P. Jenkins, Chief of the California Division of Mines. Drs. Ian Campbell, R.H. Jahns and A. E. J. Engel of the California Institute of Technology also have been particularly helpful, both in offering suggestions in the field and in critical reviews of this manuscript. Valuable field assistance was rendered by Robert S. Orr, who voluntarily aided field studies at the Talc City mine, and by William E. Ver Planck and Mort D. Turner of the California Division of Mines.Attached Files
