摘要
Based on the outcrop investigation and core borings identification,the authors systematically studied the cycle of development,the sedimentary and distribution characteristics of Neogene-Quaternary gravel layers of Kuqa Depression in Tarim Basin, to solve the problems of velocity changes and engineering decision.The gravel layers of Kuqa depression continuously developed in different periods vertically,and had different facies which changed fast laterally.The tectonic evolution,tectonic style,and the north-south faults were the main factors which influenced the sedimentary characteristics,distribution of the gravel layers.
