Annotated Bibliographies of Mineral Deposits in Africa, Asia (Exclusive of the USSR) and Australasia brings together annotated bibliographies of mineral deposits in Africa, Asia (with the exception of the USSR), and Australasia. Each bibliography is followed by notes to show the deposit's location; geological framework; age and type; structural and stratigraphic relations; conditions of formation; and position in the modified Lindgren classification. Comprised of 25 chapters, this volume begins with an introduction to the more important sources of references in the bibliographies, set down in alphabetical order with the number of references provided by each source. The distribution of deposits by continent and country follows. The deposits include molybdenum, nickel, copper, lead, and tin. Eruptive rocks, the metamorphic cycle, and the mineralization process are addressed, along with liquid immiscibility between silicate magmas and sulfide melts; the geology, mineralogy, and petrology of ore deposits in various mines; and the significance of mineralized breccia pipes. This book will be of value to mineralogists, geologists, and earth and mineral scientists as well as students interested in ore deposits.
This volume provides bibliographic and textural information which gives a real understanding of the 40 ore deposits in Western and West Central Europe. Each deposit is introduced by a selected bibliography listing the most important literature. This is followed by a detailed discussion covering geological characteristics including the position, grade and tonnage of the ore produced together with potential reserve, the stratigraphy and structure of the rocks of the district, and the characteristics and age of the ore body. The book also includes a section of maps, pin-pointing the most important mineral deposits in each region, making this work a valuable reference source for all those working in the fields of ore-deposit geology and exploration.
Few knowledgeable people would deny that the field of mineral exploration is facing some difficult times in the foreseeable future. Among the woes, we can cite a worldwide economic uneasiness reflected by sluggish and at times widely fluctuating metal prices, global financial uncertainties, and relentless pressures on costs despite a substantial slowing down of the rate of inflation. Furthermore, management is forced to tum to more sophisticated and expensive technologies and to look farther afield to more remote regions, as the better quality and more easily accessible ore deposits have now been revealed. This rather gloomy outlook should persuade explorationists to cast about for a new philosophy with which to guide mineral exploration through the challenging decades ahead. Once already, in the early 1960s, a call for change had been heard (Ref. 30 in Chapter 1), when it became obvious that the prospecting methods of yesteryear, so successful in the past, could not keep up with the rapidly growing demand for minerals of the postwar period. The answer, a massive introduction of sophisticated geophysical and geochemical technologies backed by new geo logical models, proved spectacularly successful throughout the 1960s and the 1970s. But for both economic and technological reasons, the brisk pace of the last two decades has considerably slowed down in the early 1980s, as if a new threshold has been reached.
