| 摘 要： | 阿拉善作为中国西部的一个刚性块体，岩石圈有效弹性厚度为40~50km，地壳稳定。新生代以来，由于受印度板块向欧亚板块俯冲的远程效应影响，阿拉善地块发生构造隆升，块体周缘造山带发生构造活动，但块体内部宗乃山一沙拉扎山地区新生代期间为准平原化地貌，新构造运动不发育。综合分析阿拉善地区地壳稳定性和岩体发育情况，笔者遴选出宗乃山～沙拉扎山侵入岩带作为高放废物处置库备选场址的重点工作区。

| Abstract: | Alashan block is a stable block in the west of China with effective elastic thickness of lithosphere about 40-50 kin. Due to the far field effect of the collision between Eurasian and Indian plate from Cenozoic, Alashan block was uplifted, and shew high level tectonic activity aroud the block, however, in the middle of block Zongnaishan-Shalazhashan area experienced peneplanation in Cenozoic and stayed steady. Considering the crust stability and granite distribution, we choose Zongnaishan-Shalazhashan granite pluton belt as major work area of high level radioactive waste repository. |
