Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Nature of Ore Deposits, Vol. 2 of 2 Besides the cobalt-nickel veins, the region also contains veins of carbonate spars free from cobaltiferous ores, especially an 8-meter (25-ft.) vein at the diorite contact, worked for siderite, and which is notable because it is accompanied throughout its entire course by a quartz vein containing chrome-mica. The iron deposits of Dobschau still yield an annual production of about 35,000 tons, but the cobalt veins have been abandoned for some years. The total production reported from 1840 to 1880 was 26,000 tons of cobalt-nickel ore. The cobalt veins of Thuringia differ from those of the Dobschau, just described, since they contain barite. They have been worked for many years, especially at Schweina, near Liebenstein. According to Fr. Beyschlag the veins are fault fissures with a steep southwest dip and a maximum thickness of 3/4 meter. The beds of the Zechstein formation, which dip southwest at 4 1/2, together with the copper-bearing layer of this formation, show a displacement along the veins of 3 to 8 m. (22 to 25 feet) and as much as 30 feet in exceptional cases. The vein filling consists of barite, calcspar, fragments of the country rock and smaltite, asbolite and erythrite. These vein fissures exert a remarkable influence on the bed of 'copper schist.' This Kupferschiefer is lean in this district, carrying only 1.4% of copper, and no silver, but, where it is traversed by the cobalt veins, it is enriched and holds 3 to 4% copper. At the same time the amount of copper in the uppermost layer of the Zechstein conglomerate, which immediately underlies the copper schist, rises from 3 to 10%. In particular the Beyschlag vein, discovered in 1901, proved very rich in ore. Smaltite, niccolite, asbolite, rammelsbergite, erythrite and nickel green, (zaratite?) in subordinate amount, it is true, together with chaleopyrite and tetrahedrite, were also found in the copper veins of Kamsdorf and at the Rothen Berge at Saalfeld (see p. 227). Barite and various carbonates, especially siderite, are the prevailing gangues. The fault fissures known as 'rucken' in the Mansfeld copper district also contain occasional nickelite, together with chalcocite, bornite, chalcopyrite, pyrite, calcspar, brownspar, ironspar, barite and rarely also rammelsbergite. Similar lodes in Paleozoic schists were formerly worked at Lobenstein, in the principality of Reuss. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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: Introduction to Ore-Forming Processes is the first senior undergraduate – postgraduate textbook to focus specifically on the multiplicity of geological processes that result in the formation of mineral deposits. Opens with an overview of magmatic ore-forming processes Moves systematically through hydrothermal and sedimentary metallogenic environments, covering as it does the entire gamut of mineral deposit types, including the fossil fuels and supergene ores The final chapter relates metallogeny to global tectonics by examining the distribution of mineral deposits in space and time Boxed examples of world famous ore deposits are featured throughout providing context and relevance to the process-oriented descriptions of ore genesis Brings the discipline of economic geology back into the realm of conventional mainstream earth science by emphasizing the fact that mineral deposits are simply one of the many natural wonders of geological process and evolution.

Download or read book The Geology of Ore Deposits Classic Reprint written by Herbert Henry Thomas and published by Forgotten Books. This book was released on 2018-01-13 with total page 440 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Enrichment of Ore Deposits The problems of superficial alteration and enrichment are not simple. Not only do the several metals segregate in different ways, but each metal may behave differently in different mineral associa tions. Every district and every deposit should be studied separately in the light of all available chemical and geologic data. There are, however, certain laws Of segregation that almost invariably are clearly indicated, and as data have accumulated many puzzling ap parent exceptions to these laws have disappeared. This paper is an amplification of, an earlier Survey bulletin on the enrichment of sulphide ores (bulletin It is a discussion of representative deposits, especially Of the paragenesis of their ores and of the principles that underlie the processes of enrichment. I hope it may suggest to those engaged in geologic work and in mining some lines Of approach to the solution of the complex problems that are encountered in the field. I realize fully that there may be serious omissions and possibly errors in the discussion of the complex problems here presented. I shall esteem it a favor if anyone whose statements I may have mis quoted or misinterpreted will set me right, and if those who have had superior opportunities for study Of certain districts will correct any wrong impressions that I may have given.
