摘要
阿瓦提前陆盆地位于塔里木盆地西部。新生代柯坪山脉以NE向的沙井子断裂为主滑面,剧烈向SSE方向逆冲,在沙井子断裂SE侧沉积了巨厚的新生界,向SE方向急剧减薄,形成典型的不对称挠曲沉积盆地。这种前陆盆地是大陆板块碰撞形成陆相盆地后,再次发育在造山带前缘的盆地,它发育的大地构造位置、时间以及成因,与周缘前陆盆地和弧后前陆盆地均不相同,可称之为陆内前陆盆地,是第三类前陆盆地。
Abstract
Await foreland basin is located in the northwestern Tarim Basin. In Cenozoic,Kalpintagthrusted voilently towards southeast with NE trend Shajingzi fault being its major slip plane.Great thickness of Cenozoic sediments deposited on the southeastern side of the Shajingzifault. The thickness reduced rapidly southeastward,thus forming asymmetrical fie-cure sedi.mentary basin. According to its geotectonic location,its developing time and genesis,Awati foreland basin should neither belong to peripheral foreland basin,nor belong to retroarc foreland basin. It is a new kind of foreland basin-intracontinental foreland basin.
