新疆阿克苏—乌什地区早寒武世地层出露于塔里木盆地西北缘阿克苏—乌什—柯坪三角地带,位于东经79°00′—80°30′;北纬40°40′—41°20′范围内(图1)。四十年代,B.M.西尼村曾对该区的早古生代地层作过粗略的工作。五十年代,地质部十三大队作了一比二十万区域地质调查,初步建立了该区的地层系统。以后,新疆地质局及新疆石油管理局所属地质队或地层古生物专题研究组先后多次在该区
The Early Cambrian strata in the Aksu-Wushi region of Xinjiang are exposed in the Aksu-Wushu-Keping Triangle region on the northwestern margin of the Tarim Basin and lie between 79 ° 00’-80 ° 30’E and 40 ° 40’-41 ° 20’N, Range (Figure 1). In the 1940s, B.M. Sinny had made rough work on the Early Paleozoic strata in the area. In the 1950s, the Thirteenth Brigade of the Ministry of Geology made a survey of one to two hundred thousand regional geology and initially established a stratigraphic system in the area. Later, Xinjiang Geological Administration and the Xinjiang Petroleum Administration Geological Team or the Paleontology Research Group has repeatedly in the area
