This book was released on 2018-02-08 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Geology and Ore Deposits of the Bully Hill Mining District, California The geological field work of the Bully Hill district, Upon which this paper is based, was begun July 1, 1908, and covered a period of three months. The time was found too short for a complete report and the district was again visited in the early part of July, 1912, from which time detailed study of the locality continued until September of the same year. This paper is the result of observations made in the mines in the immediate vicinity of Winthrop, Shasta county, Cal., during these two periods of study. The preparation of this report has been greatly facilitated by various courtesies rendered the writer by D. M. Riordan, President of the Bully Hill Copper Mining Smelting Co., and by John B. Keating and Herbert R. Hanley, managing officers actively. In charge at the mines. The elaboration and further study of the notes and collections were carried on in the laboratories of the Departments of Geology and Mining at Colum bia University, and the writer takes pleasure also at this point in express ing his acknowledgments to Profs. James F. Kemp, A. W. Grabau, Charles P. Berkey, and William Campbell, for advice and assistance. In order that one may appreciate at first reading the significance of some of the details which follow, and for the sake of clearness, a brief outline of the geological relationships is here given, together with' certain conclusions which have been reached regarding the genesis of the ores and the gypsum masses.

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.

Download or read book Geology and Quicksilver Deposits of the New Almaden District Santa Clara County California Classic Reprint written by Edgar Herbert Bailey and published by . This book was released on 2015-07-02 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Geology and Quicksilver Deposits of the New Almaden District, Santa Clara County, California The New Almaden district, situated a few miles south of San Jose in Santa Clara County, Calif., has yielded nearly 40 percent of the quicksilver produced in the United States. The area mapped as the district for this report includes about 80 square miles, extending south from the flat Santa Clara Valley across the moderately low foothills containing the mines to the more rugged crest of the California Coast Ranges. The rocks underlying about three-fourths of the district. Including all of the mineralized area, are assigned on the basis of lithology to the Franciscan group of Late Jurassic and Cretaceous age. The only diagnostic fossils found Indicate that the age of a part of the group Is lower Upper Cretaceous (Cenomanlan). The group consists of llthlc and feldspathic graywacke, slltstone, dark altered volcanic rocks, chert, limestone, and a subordinate amount of metamorphlc rocks, Including glaucophane schists - an assemblage regarded as a typical eugeosyncllnal suite. The thickness of the group cannot be determined accurately because of structural complexities, but the part present in the New Almaden district is believed to be at least 10,500 feet thick and may be much thicker. The sedimentary rocks are believed to have been derived from the rapid erosion of a rising landmass, and deposited In a subsiding trough which filled to wave base only in a few places near the end of the deposltlonal period. The accompanying Igneous activity Included local outpourings of lava onto the sea floor and eruption of fragmental material of similar composition which accumulated as pyroclastlc beds. The chert is abundant only In the part of the Franciscan group that contains altered volcanic rocks, and it Is believed to owe Its origin to the reaction of hot lava with sea water. The post-Franciscan sedimentary rocks, which do not occupy large areas, range in age from Upper Cretaceous to Recent. Two sedimentary units, differing in both llthology and degree of deformation, have been assigned on the basis of a few fossils to the Upper Cretaceous. The next younger sedimentary rocks are dated as middle Eocene by fossils occurring In limestone lenses near the base of a sequence of sandstones and shales. Rocks of early, middle and late Miocene age containing abundant fossils are divided Into two formations, the rocks of which grade from sandstone through clay shale to dlatoma-ceous shale. The sandy sedimentary rocks below the lowest diatomaceous bed have been assigned to the Temblor formation, and this bed and the overlying rocks have been assigned to the Monterey shale. Some included salic volcanic material Indicates igneous activity during the middle Miocene. The younger sedimentary rocks in the district are all gravel deposits, which fill the larger valleys and occur as perched remnants on some of the lower foothills. They have been divided, largely on the basis of their dissection and topographic position, Into the Pliocene and Pleistocene Santa Clara formation and Quaternary alluvium. Tabular masses of serpentine that have been Intruded into the rocks of the Franciscan group are of particular interest because altered parts of them contained the quicksilver ore bodies. Some of these masses are conformable with the rocks of the group and are therefore sills; others are intruded along faults that dip more steeply than the bedding. The larger masses consist of blocks of unsheared serpentine embedded in a matrix of sheared serpentine; the smaller masses and the borders of the larger ones consist entirely of sheared serpentine. The internal structures and details of the contacts, together with theoretical considerations, suggest that the serpentine masses were intruded as serpentine, not as peridotitic magma. The age of the serpentine cannot be closely placed by the evidence available in the district, but by comparison.

Book excerpt: Excerpt from Placer Mining for Gold in California The increase in the price of gold from in 1932 to in 1933 and to in 1934 made such stories seem even more plausible and helped further to stimulate the migration of men to the creeks, despite the unfortunate experiences related by most of those drifting back from the gold-bearing areas. Stories of those who succeeded in making a living and of the very few who made strikes continued to be magnified out of all proportion, both in passing from mouth to mouth and in the press, and brought new recruits to the streams as late as 1937.

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.

Book excerpt: Excerpt from Geology and Mineral Resources of the Neenach Quadrangle, California The only mineral production came from one tin mine and a group of three small gold mines, though there are many small workings on the south flank of the Tehachapi Range which explore gossan, tactite, or quartz bodies containing minor amounts of gold, tin, tungsten, copper, or iron. There are no indications of petroleum; two holes drilled in Antelope Valley about 1920 were dry. Exploitation of the deep ground-water supply began with the drilling of six wells in 1946.
