山西断陷带地壳深浅构造特征与地震活动李清林理辉张文玉（国家地震局地球物理勘探中心）山西断陷带有着与华北地区、鄂尔多斯块体内部明显不同的地壳深部构造特征。地表断陷盆地与隆起相间展布，地壳内低速层、高导层广泛分布，深大活动性断裂广泛发育，地壳厚度陡变，上... Tectonic characteristics and seismic activity of the crust in Shanxi rift zone LI Qing, LIN Li-hui, ZHANG Wen-yu (Geophysical Exploration Center, State Seismological Bureau) The Shanxi fault zone has distinctly different deep crustal tectonics from the North China and Ordos blocks. The surface faulted basins and the uplifts are interlaced and distributed, and the low-velocity and high-conductivity layers in the crust are widely distributed, deep active faults are widely developed, and the crustal thickness changes steeply.
