A report regarding thorium resources located in the Mountain Pass District in San Bernadino County, California

Report discussing the investigation of the Rock Corral area aimed at determining the connection between high radioactivity found during an airborne survey and the "distribution and mineralogic mode of occurrence" of this radioactivity.

Report discussing the thorium and rare-earth deposits that are found in a six-mile long belt of pre-Cambrian carbonate rocks associated with potash-rich igneous rocks of probable pre-Cambrian age in the Mountain Pass district of San Bernardino County, California.

From abstract: Airborne radioactivity surveys in the Mojave Desert region, Kern, Riverside, and San Bernardino counties were made in five areas recommended as favorable for the occurrence of radioactive raw materials: (1) Rock Corral area, San Bernardino County. (2) Searles Station area, Kern County. (3) Soledad area, Kern County, (4) White Tank area, Riverside and San Bernardino counties. (5) Harvard Hills area, San Bernardino County. Anomalous radiation was detected in all but the Harvard Hills area.

From abstract: The investigation in the Rock Corral area was undertaken to determine the relationship between 1) the anomalously high radioactivity recorded during an airborne survey and 2) the distribution and mineralogic mode of occurrence of radioactive material.

Abstract: Approximately 10 square miles of mainly igneous rocks of the western Mojave Desert were covered by this airborne radiometric survey in 173 hours of flying time.
