The Fennoscandian Shield forms the north-westernmost part of the East European craton and constitutes large parts of Finland, NW Russia, Norway, and Sweden (Fig. 1). The oldest rocks yet found in the shield have been dated at 3.5 Ga (Huhma et al. 2004) and major orogenies took place in the Archaean and Palaeoproterozoic.
The Kibara belt is an intracontinental mobile belt formed between 1400 and 900 Ma within a craton of Lower Proterozoic age. The belt's evolution started by early rifting at about 1400 Ma, and continued by transition into a marine basin filled by clastic sediments > 10 km thick, with minor basic and acidic volcanic rocks. At about 1300 Ma, the pile was deformed by thrusting and folding of the main Kibaran Orogeny and intruded by numerous large syn-orogenic granite bodies.
Металлогения Тихоокеанского Северо-Запада (Дальний Восток России): тектоника, магматизм и металлогения активных континентальных окраин. Путеводитель по полевым экскурсиям на Дальнем Востоке России: 1-20 сентября 2004 г.
This guidebook was prepared for the Interim IAGOD Conference on Metallogeny of the Pacific Northwest: Tectonics, Magmatism and Metallogeny of Active Continental Margins, which took place in September of 2004 in Vladivostok, the southernmost port of the Russian Far East. The book describes the geology of a number of important ore districts and deposits in the region. These are the major deposits of fluorine (Voznesenka), boron (Dalnegorsk), tungsten (Vostok-2), platinum (Konder), gold (Pokrovka), and some smaller deposits of tin, lead, zinc, and other metals.
A general metallogenic analysis and metallogenic zoning of the Altai-Sayan orogenic area (ASOA) were carried out in terms of the modern plate tectonics and mantle geodynamics concepts. The Altai-Sayan folded area is an example of a polyaccretionary orogenic system that resulted from the long evolution of the Paleoasian ocean. The main metallogenic belts have been recognized, in which typical ore associations (model types of mineral deposits) and their ages and geodynamic settings of formation have been established. A total of 48 metallogenic belts including 450 mineral deposits of 70 model types were studied.
Copper is the first metal which had really played a large part in human history. It is considered that Latin cuprus from which chemical name of copper originated was connected with the island of Cyprus, with the meaning ‘copper island’. But actually it is not so. The Greek word κύπρος has uncertain etymology. For copper the Greeks had a word ϗαλκός; the term “Chalcolithic” goes back to this word. Latin language had another word: aes. The combination aes cyprium meant “Cyprian copper”. Then cyprium was replaced by cuprum. All European words connected with it do not go back to a common Indo-European base. The Latin base is closer to them (Muhly 1973, p. 174, 175). <...>
The aim of this book is to summarize the current state of knowledge on the environmental geochemistry and resource potential of metallurgical slags. Hundreds of millions of tonnes of slag, a by-product of pyrometallurgical processing of ferrous and non-ferrous ores or recyclable materials, are generated annually worldwide. These slags are either landfilled, reprocessed, or repurposed.
Phase diagrams mean more to the metallurgist than mere graphical records of the physical states of matter. They provide a medium of expression and thought that simplifies and makes intelligible the otherwise bewildering pattern of change that takes place as elemental substances are mixed one with another and are heated or cooled, compressed or expanded. They illumine relationships that assist us in our endeavor to exercise control over the behavior of matter. These are no accidental by-products of a system devised primarily for the recording of physical data. They exist because the basic features of construction of all phase diagrams are dictated by a single natural law, the phase rule of J. Willard Gibbs, which relates the physical state of a mixture with the number of substances of which it is composed and with the environmental conditions imposed upon it. <...>
We start this chapter with Fig. 1.1, which shows how the price, the average grade and production of copper ore changed from 1900 to the present. At the start of last century the price was about $7,000 per ton (expressed in today’s currency); by 2002 it had decreased threefold to about $1,800 per ton, then, in the past 3 years to 2010 (when this book was written), it rose sharply to about $9,000 per ton.
Our dependence on the minerals that underpin modern life has grown enormously over the last few decades. Figure 1.1 shows the price, the average grade and production of copper ore has changed dramatically from 1900 to the present. At the start of last century the price was 7000 US$ per ton (expressed in 1998 currency) to negate the effects of inflation; by 2002 it had decreased three-fold to about 1800 US $ per ton, then, in the three years to 2010 it rose sharply to about 9000 US$ per ton before declining again in the latest recession. Over the same period, the total amount of copper mined gradually increased, except in the early 20s and 30s when both price and production dropped. How do we explain these changes, and what do they tell us about how the metal is found and mined, and about how it is used by society? Understanding these concepts is the basis of economic geology <...>
The EYCMP is a world-class gold and nickel mineral province that is reaching exploration maturity with a diminishing number of significant new finds. Effective mineral exploration is contingent on robust tectonic frameworks and knowledge of palaeo-tectonic settings (Goldfarb et al., 2001, 2005; Bierlein et al., 2002). The pmd*CRC Y1, Y2, Y3 and the current Y4 programs on the Eastern Yilgarn Craton (EYC) were established to drive geological research in the region with the aim of original new insights and models that will both aid and stimulate new approaches to mineral exploration in the region. <...>
