中-东亚能源矿产成矿域区划和盆地类型

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

根据区域构造特征、盆地演化和成矿条件等的差异,将中-东亚巨型能源矿产成矿域划分为松辽—鄂尔多斯、阿拉善—河西走廊、新疆和中亚4个成矿区。综合分析和对比多种能源矿产的成藏(矿)条件和勘探现状认为,相对稳定的区域构造背景和适度(较弱)的构造变动,是大中型砂岩型铀矿床、油气田(区)和煤田形成、共存和保存的必要条件。适于油、气、煤、铀同盆共存成藏的盆地主要为大中型内克拉通盆地、中间地块盆地以及由其肢解、分离的中小型残留盆地。中生代晚期兴衰的中型断陷盆地,也具有多种能源矿产成藏(矿)及共存的条件。

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.
