摘要
在伊犁盆地北缘和南缘下 -中侏罗统沉积微相和岩石类型研究的基础上 ,对伊犁盆地北缘和南缘侏罗纪地层进行了详细对比。认为盆地南缘下 -中侏罗统同样可以划分为八道湾组、三工河组和西山窑组 ,并分别对应于水西沟群 ～ 旋回。
On the basis of studying the sedimentary microfaces and petrology of Lower Middle Jurassic in the north and south margins of Ili basin, the authors make a detailed correlation of the Jurassic stratigraphy in the north and the south margins of Ili basin in this paper. Lower Middle Jurassic is also divided into Badaowan Formation, Sangonghe Formation and Xishanyao Formation, and they correspond separately to Ⅰ~Ⅷ cycles of Shuixigou Formation. The research has important significance to foundmetal geology and exploration of the uranium deposits in sandstone in Ili basin.
