摘要
对塔里木盆地西南缘上震旦统库尔卡克组的野外剖面观察和详细的岩相研究认为，该组中发育有典型的浊积岩系，具浊流沉积特征的鲍马序列及底面构造；浊积层系形成于深水浊积扇环境，可划分出外扇相、中扇叶状体相、中扇水道相及中扇水道间漫滩相等。指出研究区浊积岩物源来自于滨岸砂，晚震旦世强烈的裂陷作用是触发浊流形成的主要因素。
： Careful observation of the field profiles and detailed study on the lithology of the Upper Sinian Kurkak formation in the southwestern margin of Tarim basin indicated that typical turbidaite system is well developed in this formation， with the Bouma sequences and sole structure of turbidite deposit characteristics． The turbidte sequence was formed in the deep－Water turbidite fan environment， which is classified into outer fan factes， mid fan－leaf facies， mid－fan channel factes and mid－fan inter－channel overbank facies． The paper pointed out that scarce of turbidite deposits in the study area mainly came from shore sand， and that the intence faulting effect in Late Sinian was the key factor that triggered the turbidite flow．
