Excerpt from Geology and Mineral Resources of the Neenach Quadrangle, California Sir: I have the honor to transmit herewith Bulletin 153, Geology and Mineral Resources of the Neenach Quadrangle, California, prepared under the direction of Olaf P. Jenkins, Chief of the Division of Mines, Department of Natural Resources. The report is accompanied by a number of maps, charts, and illustrations, including a detailed geologic map, lithographed in color, of the 15-minute Neenach quadrangle. The area of this quadrangle is nearly 250 square miles, covering portions of the Tehachapi Mountains and Antelope Valley in Kern and Los Angeles Counties. Two famous earthquake fault zones, the San Andreas and Garlock faults, pass through the area mapped. Their junction point lies several miles to the west at Gorman and Lebec where State Highway 99 cuts through the Tejon Pass. It is significant that the area mapped contains tin deposits discovered and prospected during World War I. These, together with gold, copper, tungsten, molybdenum, marble and limestone, crushed rock, volcanic ash and ground water, are described in this bulletin. The author, John H. Wiese, prepared the report while in the employ of the United States Geological Survey and in connection with graduate study at the University of California at Los Angeles. Cooperating with the Federal Survey and the State University, the State Division has helped to sponsor the undertaking and is publishing the results of the work as one of its series of bulletins.
