冀东中生代凹陷与辽西中生代凹陷在地质上的差异

The Geological Different Between Yidong Mesozoic Era Hollow and Liaoxi Mesozoic Era Hollow

冀东、辽西是“燕山运动”的发祥地,两区同处于燕辽沉降带中,在地质上是可类比的,但在中生代火山岩凹陷区的形态、构造、地层等诸方面都存差异。差异的分界是凌源—杨杖子断裂。这些差异对矿产资源的寻找和地质单元的划分都有影响。

Yidong and Liaoxi are analogical in geology because the place of origin of 'Yanshan movement'and they are in settling band of Yanliao, Mesozoic Era Hollow. But there are different in shape, structure and geo- sphere of area of mesozoic era extrusive rock hollow. The boundary line of different is break between Lingyuan and Yangzhangzi. These different have effect on finding mineral resource and dividing geology unit.
