羌塘盆地位于特提斯构造域的东段,分布在羌塘—昌都地块中西部,夹持于可可西里—金沙江与班公湖—怒江2条缝合带之间,包括中央隆起带在内残留面积约为18×104km2,是青藏高原上面积最大的中生代海相残留盆地,勘探前景乐观。对于中生代时期羌塘盆地在特提斯域中的位置和盆地的性质,存在不同认识,综合分析后认为:羌塘盆地中生代属于劳亚大陆南缘,为一个典型的叠合盆地,先后经历了北羌塘前陆盆地演化阶段、羌南裂谷阶段、被动陆缘裂陷阶段、被动陆缘拗陷阶段和羌塘盆地萎缩阶段等5个演化阶段。
The Qiangtang Basin is located in the eastern segment of the Tethys tectonic domain and is located in the central and western Qiangtang-Changdu massif. It is sandwiched between two straps of the Hoh Xil-Jinsha River and the Bangong Lake-Nu River, including the central uplift belt The residual area is about 18 × 104km2, which is the Mesozoic marine residual basin with the largest area on the Qinghai-Tibet Plateau. The exploration prospect is optimistic. There are different understandings on the location of the Qiangtang Basin in the Tethys area and the nature of the basin during the Mesozoic. According to the comprehensive analysis, the Mesozoic in the Qiangtang Basin belongs to the southern margin of the Lauamu continent and is a typical superimposed basin. The northern Qiangtang foreland basin evolution stage, the southern Qiangnan rift stage, the passive continental margin rifting stage, the passive continental margin depression stage and the Qiangtang basin shrinkage stage.
