在已完成的新疆地学断面研究计划实施中曾在西昆仑山前布置了14个宽频带地震台站.利用记录到的远震P波初至和层析成像方法,研究了西昆仑造山带下的岩石圈地幔结构特征.在已有地震学证据基础上,层析成像结果显示,西昆仑造山带下的高速岩石圈地幔可能是印度岩石圈地幔的俯冲前缘.沿东经80°深度剖面图像显示,在西昆仑造山带下的150~300km处,高速异常的岩石圈地幔前锋与低速异常的塔里木块体岩石圈地幔发生了面对面碰撞.
14 completed broadband seismic stations have been arranged in front of the West Kunlun Mountains in the completed research project of geosciences in Xinjiang.Using the teleseismic P wave first arrival and tomographic imaging method recorded in the West Kunlun orogenic belt Based on the available seismological evidence, the tomographic results show that the high-velocity lithospheric mantle beneath the western Kunlun orogenic belt may be the subducted front of the lithospheric mantle in India along the 80 ° depth profile It shows that the collision between the high-speed anomaly lithospheric mantle forward and the low-speed anomalous Tarim Block lithospheric mantle occurred at 150 ~ 300km below the western Kunlun orogen.
