摘要
秦皇岛柳江盆地自燕山运动以来，岩浆活动十分剧烈，岩浆岩广泛发育，说明它已从稳定区转化为活动区，成为后地台阶段的活化区，即地洼区。因而其成矿作用具有稳定型和治化型两类特征。
Magma activities in Qinghuangdao Liujiang Basin have been very violent since Yanshanian movement, and Magma rocks are very spread. It demonstrates that Qinghuangdao Liujiang Basin has changed from a steady region into an active region and become the active region of post platforms,that is Diwa region. So its mineralization includes two characteristics which consist of steady type and active type.
