摘要
在青藏高原北缘1:25万区调工作中,于新疆且末县黄羊沟、西长沟一带原下石炭统地层中首次采获丰富的早三叠世孢粉化石,通过岩石组合、沉积特征、地质时代的研究,将含早三叠世化石的地层体从下石炭统地层中分离出来,厘定为下三叠统西长沟组,并探讨了该组的地质意义。
During regional survey with scale of 1 ： 250, 000 at north margin of Qinghai - Tibet Plateau,plentiful palynologic fossils of lower Trassic was collected at first within the lower Carboniferous beds along Huangyanggou - Xichanggou at Qiemo County, Xingjiang Province, through studies on lithologic combination,sedimentary feature and geologic ages, the strata in bearing lower Trassic fossils are separated from lower Carboniferous beds, which is defined to Xichanggou Formation of lower Trassic and its geologic implication is discussed.
