This book was released on 2017-11-18 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Mineral Resources of the Agua Tibia Primitive Area, California The Agua Tibia Primitive Area includes about 43 square miles of the Cleve land National Forest in San Diego and Riverside Counties near the Pala and Rincon pegmatite districts. The area contains Agua Tibia Mountain, which rises about feet higher than the adjacent lowlands. Most of the moun tain is covered by dense brush. Small stands of timber are present on the crest of the mountain and at the bottoms Of canyons. The principal rocks Of the primitive area are crystalline and consist of both metamorphic and plutonic varieties. The metamorphic rocks have been correlated with both the Bedford Canyon Formation and the Julian Schist of Jurassic or Older age. The plutonic rocks include San Marcos Gabbro, Bon sall Tonalite, and Woodson Mountain Granodiorite Of Cretaceous and per haps Older age. Pleistocene and younger sedimentary deposits, chiefly Temec ula Arkose Of Mann fanglomerate, and terrace deposits, cover much of the north and west perimeter of the area. The Temecula Arkose and other rocks are cut by faults, the largest of which are part of the Elsinore fault zone. NO economic mineral deposits were found during the reconnaissance study of the primitive area. Analyses of more than 100 samples of stream sediments and bedrock collected in and adjacent to the area did not indicate the presence of geochemical anomalies commonly associated with economic mineral deposits. Magnetic anomalies detected by an aeromagnetic survey are believed to be related to gabbroic bedrock and not to economic deposits of magnetic minerals. NO prospect pits or mines were seen, nor did a search of legal records reveal the existence of past or present mining claims in the primitive area.

This book was released on 2015-06-28 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Minerals of California Classic Reprint written by Arthur S. Eakle and published by Forgotten Books. This book was released on 2017-10-12 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Minerals of California Since the appearance of the second list, our knowledge of the geology and mineralogy of the State has vastly increased. The ore deposits of many of the counties, the gem and borate deposits of the southern counties, and the petrography of many districts, have been investigated and described, so that our present knowledge of the mineralogy of the State is much more general. The present list contains more than double the number of definite mineral species given by Hanks, besides many sub-species and varieties. The desire has been to make the list as complete as possible of the known minerals, and where they occur, but the list of localities where the same mineral might be found is necessarily incomplete. Many minerals are so commonly distributed throughout the State, such as small bodies or pockets of metallic minerals and the rock-forming minerals, that it would be useless and impossible to cite all of their occurrences. In such a vast area as California, localities may be known to local col lectors where excellent specimens may occur, unknown to the author. Some minerals may be known to occur in the State which have not been mentioned in this work, but it is believed that they will be very few in number.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from California Mines and Minerals The subject matter of this work is confined as far as possible to a plain statement of facts, regarding our great state and its mineral wealth. It has been a difficult and laborious task to gather all the data and statistics, as aside from a few counties, whose citizens were public spirited enough to look after their county interests, all matter has been prepared from the Secretary's office. In the early stages of the labor, much assistance was promised by members of the Association and others, in the form of special articles upon subjects of great interest to the industry, as well as reports upon various counties and their resources. As the work progressed, however, it was found that many substitute articles would be necessary, as promises make poor reading matter. The Association is indebted to the contributors, whose articles upon various subjects will be found highly interesting and instructive; to the advertisers, whose solid financial support has materially assisted in defraying the cost of publication; to Mr. J. O. Denny, whose able and conscientious services have been indispensable in the editorial work, and to the publishing house, for the extra care and attention given to the general make-up.

This book was released on 2015-07-27 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Mines and Mineral Resources of Del Norte County, Humboldt County, Mendocino County The three counties presented herewith constitute the northernmost coast group, being at the northwest corner of the State and bordering on the Pacific Ocean. Until quite recently - in fact, subsequent to writing the body of this report - the only transportation connection Del Norte and Humboldt counties had with the rest of the world was by water. Eureka, Fort Bragg and Crescent City being the principal ports. The Northwestern Pacific Railroad has now been completed. through to Eureka, giving all but the extreme northern section a direct rail route to San Francisco. A railroad connection to Crescent City is at present under construction from Grant's Pass, Oregon. The principal industries of this district are lumbering, dairying and agriculture, the mineral output, except for Humboldt, being as yet small. The undeveloped mineral resources, however, are great, the exploitation of which is dependent mainly on improved transportation facilities. Acknowledgment is here made of assistance rendered by the various owners of properties, both during the field work and in the subsequent preparation of this report.

Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
