根据我队1973—1976年一比五万区测及近年来在吉林南部取得的一些新成果,笔者应用陈国达教授“地洼说”的观点,分析了我区地洼期的一些基本特征。认为,自晚三迭世,本区在地台的基础上发展成新型的活动区——地洼区。其以断块为特色的构造活动开始增强,造成区内反差强度大的一系列陆相断陷盆地。 义和盆地位于辽东地穹系浑江地洼列临江地洼(图1)。该区地槽发育阶段的基本构造层为太古界(总厚大于9720米)与下元古界(总厚大于21,993米)。地台阶段为震旦界至二迭
According to my team from 1973 to 1976, a region of fifty to fifty thousand and some new achievements made in southern Jilin in recent years, the author applied Professor Chen Guoda “to depression” point of view, I analyzed some of the basic characteristics of the depression period. He believes that since the late Triassic, the district has developed into a new type of activity area - Diwaka on the basis of the platform. The tectonic activities characterized by fault blocks began to increase, resulting in a series of continental rift basins with high contrast intensity. Yihe Basin is located in Liaodong to the dome of the Hunjiang River depression depression Riverside depression (Figure 1). The basic tectonic layer of the geotectonic stage in this area is Archean (with a total thickness greater than 9,720 m) and the Lower Proterozoic (total thickness greater than 21,993 m). Floor stage for the Aurora bound to Diego
