据吉林省中生代地层建造类型、生物群特征和岩浆活动以及构造变动的形式,燕山运动期次划分如表2所示。从吉林省不同地区地质资料分析来看,地壳运动不论在空间还是在时间上发展都是不平衡的,但仍存很大程度的可比性(表1)。现分区论述如下: According to the type of Mesozoic stratigraphic construction in Jilin Province, the characteristics of biota, the magmatic activities and the tectonic changes, the Yanshan movement periods are shown in Table 2. Judging from the geological data of different areas in Jilin Province, the crustal movement is unbalanced both in space and in time, but it still has a large degree of comparability (Table 1). Now divided as follows:
