Subdivisions of the Central-East Asia Multi-Energy Minerals Metallogenetic Domain and Types of Those Basins

Abstract

Abstract: According to the different characteristics of regional structures, basin's evolutions and mineralization conditions, the Central- East Asia energy minerals metallogenetic domain (CEAMD) can be divided into such four mineralization zones as Songliao-Ordos, Alashan-Hexi corridor, Xinjiang and Central Asia ones. The comprehensive analyses and comparisons of accumulation/mineralization conditions and current exploration of multi-energy minerals show that the relatively stable regional tectonic background and moderate (weaker) structural deformation are probably the necessary conditions for the formation, coexistence and preservation of large- and medium-sized sand-type uranium deposits, oil-gas fields and coalfields. The primary basins suitable for coexistence and accumulation of oil-gas, coal and uranium are the large- and medium-sized intracraton basins, intermediate massif basins and correspondingly split medium- and small-sized relic basins. The medium-sized rift basins developed in late of Mesozoic are also of the conditions of accumulation/mineralization and coexistence of multi-energy minerals.

Key words: Central Asia, East Asia, energy minerals metallogenetic domain, hydrocarbon, sand-type uranium deposit, mineralization subdivision, energy minerals basin type
