| 摘 要： | 由于地幔柱的作用,新元古代晚期至古生代早期在塔里木板块东北部曾发育一个坳拉谷,称之为库满坳拉谷。在库鲁克塔格和满加尔凹陷地区,从早震旦世到奥陶纪发育中酸性和基性双峰火山岩建造、深水碳酸盐岩和复理石沉积体系,具坳拉谷盆地沉积特征;志留系-石炭系具有坳陷盆地沉积特征;上石炭统-二叠系缺失;中生代发育陆相沉积体系,标志着强烈造山运动盆地隆起消亡。这些地层层序构成了典型的坳拉谷盆地沉积体系,完整地记录了库满坳拉谷从产生至消亡的构造发育史。

| Abstract: | The mantle pluming once caused the formation of an aulacogen called the Kuruktag-Manjiar aulacogen in northeastern Tarim plate during the Late Neoproterozoic to Early Palaeozoic. In the Kuruktag-Manjiar zone, the intermediate-acidic and basic bimodal volcanic formations, deep-water carbonate rocks and flysch depositional systems which are typical of rift basin deposits were developed during the the Early Sinian to the Ordovician. Later on the Upper Carboniferous-Permian strata are missing. Till the Mesozoic, the continental depositional systems began to be developed. All these reflect intense orogenic processes, and the uplifting and collapse of the basin cited above. The stratigraphic sequences in the basin are characteristic of typical aulacogen depositional systems, and recorded complete history of tectonic evolution from the initiation to termination of the Kuruktag-Manjiar aulacogen. |
