Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Geology of Ore Deposits The original source of all ore deposits lay in the primitive igneous crust of the earth and in those igneous rocks which subsequently penetrated it from the interior. It may thus be said that the source of all ore deposits may ultimately be traced to rocks with igneous characteristics. The igneous rocks which carry, or are answerable for, the richest metalliferous masses are mainly those of the larger intrusions. These are deep-seated or plutonic in Character, by which is meant that they never reached the earth's surface in a fluid state, but were covered to a considerable depth at the time of their consolidation. Generally speaking, the older igneous intrusions - that is to say, those which belong to the pre-cambrian and Palaeozoic periods - are richer in ore deposits than those which have been intruded at a later date.

Book excerpt: Excerpt from Geology and Ore Deposits of the Republic Mining District Ou the east side of the Cascade mountains three sites were selected as follows: At Selah Gap, two miles north of North Yakima, in Yakima county; at Marshall, a few miles southwest of Spokane, in Spokane county; and at Dixie, 11 miles north east of Walla Walla, in Walla Walla county. At all of these places basalt of good quality occurs in sufficient quantities to supply large crushing plants for a great many years. In each instance a railway line passes directly by the quarry, thus making the shipping problem an easy one.

Download or read book Geology of Colorado Ore Deposits Classic Reprint written by Arthur Lakes and published by Forgotten Books. This book was released on 2017-09-12 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Geology of Colorado Ore Deposits This treatise contains the substance of a series of elementary lectures delivered by the author to the students of the Colorado State School of Mines. It is published with a view of meeting some of the needs of the general public, of the ordinary miner, and of the unscientific many, rather than with any idea of offer ing original matter for the discussion of the scientific few. The materials are derived partly from the writer's own researches, and largely from the most reliable resources available to him, such as the standard text-books and the valuable published reports of the United States Geological Survey. The writer having for a time been connected with that survey, knows full well how high a value is to be attached to those reports, which must remain for all time as a standard of reference for those interested in the geological relations of the mines of Colorado. The first part of the work contains a rough sketch of general Geology, for the benefit of those who are not familiar with the terms used in this science. The sketch is further applied to the local geology of Colorado. The second part refers to the phe domena of veins and ores, and their surroundings, as illustrated by Colorado.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Geology of Western Ore Deposits The first and most ancient rock series, which underlies all others, and may be called the bedrock of the world, is the granitic. This is commonly assumed to be of Archean age, or to have been formed and up heaved in the earliest period of the world's existence of which we have any cognizance. This is doubtless true in the majority of cases, but there is evidence that some granites, such as those of Pike's Peak and the Cripple Creek region, were upheaved or erupted at a later date.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Geology and Ore Deposits of the Bonanza District: Saguache County ColoradoThe mining town of Bonanza furnishes an admirable example of that astonishing mushroom growth that has characterized the founding of so many mining camps in the Cordilleran west. Not only in its sudden growth from nothing to a populous mining community, but in its almost equally rapid decline after its failure to live up to the early expectations of limitless wealth has Bonanza many parallels in the Rocky Mountain mining districts. That, however, the town as a mining camp has persisted and today is able to show no little interest in the development of its mining resources, may be attributed to the fact that such resources do exist, and that those interested in their development have not lost faith in their ultimate success.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
