高放废物处置库深部地质特征研究

摘要

To find out the deep geological characteristics of high -level radioactive waste disposal repository .U-sing magnetotelluric method ,the controlled source audio magnetotelluric method and high -precision magnetic method for comprehensive geophysical prospecting and data interpretation ,get 6 lines'results interpretation chart of integrated geophysical .According to the anomalous characteristics of the results interpretation chart , deduced that the granite controlled by both the north and south sides of two near ? EW trending faults F 1 and F2 ,with a wide distribution in fracture zones ,and fault filling heat alteration material .The granite rock mass have no obvi-ous internal fault development .%为查明高放废物处置库深部地质特征，采用大地电磁法、可控源音频大地电磁法以及高精度磁法进行综合地球物理勘探与资料解译，得到6条测线的综合地球物理成果解译图。根据成果解译图的异常特征，推断出研究区花岗岩体受南北两侧两条近东西向断裂F1、F2控制，破碎带分布较宽，断层充填高热蚀变物质，岩体内部无明显断层发育。
