李四光同志指出,目前“所提出的构造型式,大都是燕山运动以来的产物。由于这些较新的构造型式比较容易鉴定,所以就把它们当作头一步的研究对象”至于更古地质时代的“古构造层”中存在着的“古构造体系”还要进一步研究。 本文试以地质力学的理论和方法,探讨燕山、辽东及其相邻的胶东、晋东北地区燕山运动以前形成的主要古构造体系。在研究过程中,以各地质时期的古构造形迹分析为基
Comrade Li Siguang pointed out: At present, most of the proposed structural types are the product of the Yanshan movement. Since these newer types of structures are relatively easy to identify, they are regarded as the first step of the study. “As for the ancient geological times” Paleo-structural layer “exists in the” ancient tectonic system "should be further studied. This paper attempts to geomechanics theory and methods to explore Yanshan, Liaodong and its adjacent Jiaodong, northeastern Shanxi Yanshanian movement before the formation of the main ancient system. In the course of the study, the palaeo-structure trace analysis of each geological period is taken as the basis
