摘要
里龙乡位于西藏林芝地区米林县,雅鲁藏布江与里龙河谷交汇处。近年的研究发现,该地区可能发育有一条或数条活动断层1。为了对今后的公路桥梁、隧道等工程建设提供较为准确的参考依据,2013年对该地区进行了详细的调查。研究中采用了野外实地调查,化探采样进行室内分析等方法,逐步了解清楚该地区断裂的构造、展布特征以及活动性的特点。此次调查发现,里龙断裂为一条全新世仍在活动的,具有以走滑性质为主的逆断层。
Lilong,located in Milin County,Linzhi District of Tibet,is in the junction of Yalu Tsangpo River and Lilong River valley.In recent years,the study found that there may be one or several active faults in the area.Detailed investigation of the area was made in 2013 to provide accurate geology for road,bridge and tunnel construction.Field investigation and geochemical sampling were carried out to find the features of structure,distribution and activity of the fault.The study found Lilong Fault is a Holocene-active reverse fault with strike slip.
