Abstract: | The outcropping strata in the Kuluketage fault-uplifted zone of Tarim Basin,Xinjiang is a succession of bathyal-neritic deposits including phosphate rock,siliceous rock,volcanic rock,gypsolith,nodular limestone,carbonate tempestite,oolitic limestone and carbonate turbidite.There are twoⅠ rank sequences made of thre eⅡ rank sequences and eleven Ⅲ sequences,reflecting three ranks of sea level changes.The sea level change of Ⅲ rank controlled Ⅲ rank sequences with six developing models are related to the special environments and their changes.The Ⅱ rank sequences are the products of tectonic stages of the basin evolution,which are early Cambrian rifting stage,middle Cambrian rifting and sagging stage and late Cambrian sagging stage.There were 2 maximum sea flooding events in the early and late Cambrian.The late Cambrian event coincides with global sea flooding while the one in the early Cambrian is local. |
