The Asian continent is the main part of the greatest continental plate—Eurasian plate, on the Earth. The Asian continent covers the tremendous area and has a very long geological history, complex intraplate deformations, a lot of mineral resources and the changeable ecologic environment. Researching the Asian tectonics, which plays a dominant role in the resources and environments, is an interesting subject. With the rapid development of society and economy, it is becoming more and more important, interesting and urgent to re-recognize and understand the relationship between the Asia tectonic evolution and giant ore deposit (including giant or supergiant ore fields and provinces) from the perspective of lithospheric plate tectonics.

Post-Collisional Magmatism and Its Relationship to Late-Variscan Ore Forming Processes in the Erzgebirge (Bohemian Massif)

Постколлизионный магматизм и его связь с поздневарисканскими рудообразующими процессами в Эрцгебирге (Богемский массив)

The main goal of this contribution is to document the possible importance of post-collisional lamprophyre intrusions for late-Variscan ore mineralization in the Erzgebirge (Germany and Czech Republic). Located at the northwestern border of the Bohemian massif in the Internal Variscides, the Erzgebirge is one of the most important silver, tin, tungsten, uranium, lead, zinc, copper, indium, bismuth, cobalt, and fluorite ore deposit provinces in Europe with a mining history of more than 800 years. Because of the close spatial association between late-Variscan ore mineralization and Permo-Carboniferous lamprophyric and rhyolitic intrusions the Erzgebirge is one of the key localities to study the genetic relationship of epigenetic Sn-W-Mo, Ag-base metal, and U deposits with post-collisional, mantle derived magmatic pulses.

The report that follows presents a first statement of the results of a study sponsored by the European Economic Community and the Department of Trade and Industry as communicated to a meeting of the Institution of Mining and Metallurgy Midlands Section at which the President (Dr A. J. Robinson) and the Section Chairman (Professor N. A. Warner) were present. It was my privilege to attend and to make some concluding remarks; these form the basis of this preface. The Geological Survey, now in its 154th year, has as one of its principal objects the provision of geological maps based on surveying in maximum detail at a scale of 1:10 000. In areas where extractive or other engineering industry is important, the surveys have been revised more than once as new subsurface data became available.

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.

Изучение процессов формирования и позднейших преобразований континентальной коры фанерозойских складчатых поясов, выявление связей геологии и тектонического строения орогенических областей с закономерностями размещения в их пределах месторождений полезных ископаемых - актуальные задачи геологической науки.

It is a daunting task for any geologist to understand gold genesis and to find exploration guidelines in the enormous volume of literature. From the perspective of the exploration geologist, this is worth tackling because there is still a large dichotomy when it comes to their genesis, epigenetic-structural aspects and syngenetic concepts. While the targets will not change with the model (Colvine et al., 1984), a better overall understanding will clearly aid target selection and exploration techniques <...>

В настоящее время уран является одним из важнейших энергоносителей. Рост энергопроизводства, необходимый для экономического развития России, в ближайшие десятилетия будет обеспечиваться, главным образом, за счет атомной энергетики, что обусловлено чрезвычайной растянутостью транспортных коммуникаций страны и удаленностью источников энергии от центров энергопотребления [Атлас «Уран России» 2000].
