| 摘 要： | 塔里木盆地巴什托区石炭系自下而上分别为巴楚组、卡拉沙依组和小海子组。岩石类型有碎屑岩和碳酸盐岩,并夹薄层膏岩。沉积相主要为碳酸盐台地,包括蒸发台地、局限台地、开阔台地3 种亚相和6 种微相;巴楚期晚期,物源向北或北东方向退却,陆源碎屑物质注入急剧减少,形成了一套富含生物碎屑的碳酸盐岩地层,发育了局限台地亚相沉积;卡拉沙依期早中期为蒸发台地夹局限台地亚相沉积,晚期为局限台地环境;小海子期海侵范围扩大,大部分地区为开阔台地亚相沉积。

| Abstract: | The Carboniferous in Bashituo block of Tarim basin is divided into Bachu formation,Karrathayi formation and Xiaohaizi formation,with rock types of clastic rock,carbonate rock and laminated gypsolyte.The sedimentary facies is dominated by carbonate platform which includes three sub-facies of evaporation platform,restricted platform,open platform and six micro-facies.In the late Bachu the source area was retrograded towards north and northeast direction,and the terrigenous clastics trended towards rapid decre... |
