From abstract: "This study was made to describe the distribution of inorganic nitrogen and other chemical constituents and nitrogen-using bacteria in the unsaturated zone, to relate nitrogen occurrences, in a general way, to present and historical land use, and to attempt to predict nitrogen concentrations in ground water after recharge" within the Highland-East Highlands area of San Bernardino County, California. It includes maps, graphs, and tables.

Report discussing the search for uraniferous coal in areas of California, Oregon, and Nevada. The reconnaissance and its results are described in sections divided by regions searched.

"The primary purpose of this report is to present data pertaining to the occurrence, distribution, and geologic environment of deposits of radioactive minerals in California. A secondary purpose is to summarize the information available on occurrences in California and to present a brief description of each radioactive locality that was known prior to 1953."

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.

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.

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.

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

A report about fossils from the Chico-Téjon series of California. These fossils constitute additions to the already known molluscan fauna of an important series of rich strata.

A report about volcano response plans. It discusses a four-level color code with successive conditions. For instance, green means no risk while red means an eruption is occurring.

From abstract: A complex Neogene history characterizes the offshore Santa Maria basin and the northwest margin of the western Transverse Ranges, California. This history includes the transition from subduction to a transtensional and then transpressional plate boundary, including about 900 of clockwise rotation of the western Transverse Ranges. This report uses seismic reflection data to document the geometry of structures that accommodated this deformation and offshore well data to date and correlate the sediments which were affected by the different tectonic episodes.

From preface: This report satisfies the demand of the public for reliable information and to gather data which should be of use in planning further geologic work in Nevada.

Preface: The author of this paper gives a thorough description of a complex of very unusual igneous rocks and associated hydrothermal deposits.
