摘要
利用成因地层分析的方法，对伊犁盆地南缘侏罗系水西沟群进行沉积特征及沉积环境的分析，并对其沉积旋回进行了统一划分和对比，认为水酉沟群自下而上，可划为8个旋回；I—Ⅳ旋回属于冲积扇沉积；
The method of genetic strata analysis is applied to analyze seditnentary features and environmentof Shuixigou Grpup of Jurassic at southern rnargin of Ili basin, and conduct uhified division and correlation of sedimentary cycles. Eight cycles are subdivided from lower to upper of Shuikigou Group. I-Ⅳ cycle is of fluvial fan sediments, and V-Ⅷ cyc1e of fan delta sediments.
