摘要
本文从滇蜀地区地壳磁性层顶面前寒武纪结晶基底入手,讨论了该区前寒武纪结品基底构造特征及其与地震活动的关系,并对两者进行了相关分析。指出区内的地震活动范围、位置、强度和深度受前寒武纪结晶基底的起伏构造形态和深度的影响与制约。
Based on Precambrian basement, crustal magnetic layer's top, in Yunnan-Sichuan, the characteristics of Precambrian basement and its relation to seis-micity in the area have been discussed, further, the correlation analysis between them has also been done in this paper. The study shows that the range, location, intensity and depth of earthquakes are effected and restricted by the rolling topography of Precambrian crystal basement.
