Позднепермское-раннетриасовое завершение аккреции южных Алтаид: значение для геодинамической эволюции, фанерозойского роста континента и металлогении Центральной Азии

The Altaids is one of the largest accretionary orogenic collages in the world with the highest rate of Phanerozoic continental growth and significant metallogenic importance. It is widely accepted that subduction-related orogenesis of the Altaids started in the late Precambrian and gradually migrated southward (present coordinates). However, it is uncertain when and how the building of the Altaids was finally completed.

The Asian continent formed during the past 800 m.y. during late Neoproterozoic through Jurassic closure of the Tethyan ocean basins, followed by late Mesozoic circum-Pacific and Cenozoic Himalayan orogenies. The oldest gold deposits in Asia reflect accretionary events along the margins of the Siberia, Kazakhstan, North China, Tarim–Karakum, South China, and Indochina Precambrian blocks while they were isolated within the Paleotethys and surrounding Panthalassa Oceans. Orogenic gold deposits are associated with large-scale, terrane-bounding fault systems and broad areas of deformation that existed along many of the active margins of the Precambrian blocks. Deposits typically formed during regional transpressional to transtensional events immediately after to as much as 100 m.y. subsequent to the onset of accretion or collision. Major orogenic gold provinces associated with this growth of the Asian continental mass include:

Книга содержит новые сведения по морфологии, систематике, стратиграфическому и географическому распространению ископаемых ящериц (отряд Lacertilia) Центральной Азии (Монголия и прилежащие страны). Столь широкий охват данных в исследованиях по истории группы для данной территории ранее не предпринимался.

A variety of global and regional classifi cation schemes for uranium deposits have been proposed in the past by a number of geoscientists including Heinrich (1958), Roubault (1958), Ruzicka (1971), Ziegler (1974), Mickle and Mathews (1978), Mathews et al. (1979), Nash et al. (1981), Barthel et al. (1986), Dahlkamp (1989, 1993), McKay and Miezitis (2001) mainly for deposits in the western hemisphere and by Kazansky and Laverov (1977), Boitsov (1989, 1996),

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.

Эта книга — вторая часть учебника по физической географии Советского Союза. Она содержит характеристику природы н естественных ресурсов Средней Азии, Казахстана, Сибири и Дальнего Востока. Учебник по сравнению с третьим изданием (1978) исправлен и дополнен с учетом новых достижений науки и задач хозяйственного освоения восточных районов СССР.

These bibliographies and the notes that accompany them have been prepared to aid the economic geologist in his study of ore deposits; they certainly will not do all his work for him. I have tried to include all ore districts in Africa, Asia (exclusive of the U.S.S.R.) and Australasia for which sufficient material is available in print to permit a student of ore deposits to obtain a real understanding of any one of the deposits. I have tried to include as many references as possible in languages other than English. <...>

This report on nonfuel mineral deposits and resources of the Asia and the Pacific region is one of a series of geologic regional reports produced by the U.S. Geological Survey to provide up to date summary information of known and undiscovered mineral resources around the globe (Cunningham and others, 2005; Nokleberg and others, 2005; Zientek and others, 2005). These geologic regional reports are designed to be informative with respect to the location and endowment of mineral resources for each region. Boundaries of these regions are those of the USGS Minerals Yearbooks, which monitor production and economic factors affecting the mineral industries of the regions. Additional and historic information related to mineral production statistics also can be found in the Yearbooks. The area described within each of the regional reports is shown on Figure 1 and the Yearbooks are available on line at http://minerals.usgs.gov/minerals/pubs/myb.html. <...>

В монографии приведены новые данные по биогеохимическим исследованиям на золоторудных, оловянных и редкометалльных месторождениях Узбекистана с целью разработки теоретических основ биогеохимического метода поисков месторождений применительно к аридным условиям Средней Азии. Освещены особенности миграции в накопления цветных, редких и благородных металлов в почвах, водах и растениях в зонах оруденения и вне их. Результаты исследований по распределению и накоплению вольфрама показали возможность использования его в качестве критерия при поисках скрытых скарново-шеелитовых месторождений в условиях пустыня.
Для геологов, занимающихся поисками рудных месторождений.

Настоящая работа посвящена выявлению основных закономерностей латеральной изменчивости и эволюции вулканизма орогенного этапа развития фанерозойскях складчатых поясов Азия.
Вслед за А.А.Богдановым, А.А.Моссаковским, В.Е.Хаяным, Н.П. Херасковым и др.ив соответствии с известными представлениями о стадийности преобразования океанической коры в континентальную земную кору (Тектоника Сев.Евразии, 1980) автор понимает ороген-ный этап как завершающий этот процесс, отвечающий континентальной стадия развития складчатых поясов и характеризующийся осадкона-коплением и вулканизмом в условиях горного расчлененного рельефа.
