离石断裂带的构造及其地震危险性

The Structure and Earthquake Endangerment of “Lishi Fault Zone”

在山西断陷带西侧吕梁隆起的西坡上,有人认为有一条纵贯全区的离石断裂带,并把其作为鄂尔多斯断块和太行山断块的分界断裂,本文通过近期的工作结果及对深部构造、岩浆活动和钻孔资料的分析,认为把离石断裂带作为构造单元的分界断裂的依据不足。

Some people hold that there exists a“Lishi Fault Zone”running through the whole of Luliang Region on the up-warping west slope on the west side of Shanxi Rift and that it can be regarded as the boundary, fault between the Erdu-os Block and the Taihangshan Block:On the basis of their recent work and analyses of deep structure, magmatic activities and dill data,the authors don't think it dependable to regard “Lishi Fault Zone” as the bourdary fault between tectonic units.
