Download or read book The Nature of Ore Deposits Vol 2 of 2 Classic Reprint written by Richard Beck and published by . This book was released on 2015-07-01 with total page 352 pages. 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.

Download or read book Economic Geology written by Walter L. Pohl and published by John Wiley & Sons. This book was released on 2011-03-03 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity’s ever-increasing hunger for mineral raw materials, caused by a growing global population and ever increasing standards of living, has resulted in economic geology becoming a subject of urgent importance. This book provides a broad panorama of mineral deposits, covering their origin and geological characteristics, the principles of the search for ores and minerals, and the investigation of newly found deposits. Practical and environmental issues that arise during the life cycle of a mine and after its closure are addressed, with an emphasis on sustainable and "green" mining. The central scientific theme of the book is to place the extraordinary variability of mineral deposits in the frame of fundamental geological processes. The book is written for earth science students and practicing geologists worldwide. Professionals in administration, resource development, mining, mine reclamation, metallurgy, and mineral economics will also find the text valuable. Economic Geology is a fully revised translation of the the fifth edition of the German language text Mineralische und Energie-Rohstoffe.
