摘要
Since the end of the Paleozoic, various crustobodies of the Asian continental lithosphere have successively undergone activation, resulting in the formation of widespread diwa-regime mobile belts. This is one of the important events in the evolution-movement history of the Asian continental lithosphere, occupies an important position in the problems of global tectonics and forms a frontier subject in modern geoscience. This paper, from an angle of crustobody geotectonics, discusses the following problems: formation time, distribution 1imits, types, development peculiarities and geotectonic significance of the diwa-regime tectonic element ; geochemical conditions of ore formation, principal mineral associations and ma jor deposit types in diwa structures of the Asian continent and their difference from those in other tectonic elements i and relationships between diwa-type metallogenesis and polygenetic compound and ultragiant ore deposits. Such a discussion can contribute to a better understanding of the tectonic types, distribution pattern and economic value of non-ferrous and rare meta1 endogenic ore deposits, peat, lignite and oil-gas fields.
