摘要
鸡西盆地早白垩世早期为裂陷作用,受敦密断裂控制,早白垩世晚期,盆地周边隆起,燕山晚期,本区以断裂和火山活动为主。新生代,鸡西盆地受新构造运动的控制,敦密断裂再度活跃。喜山运动形成平麻断裂。本文通过对鸡西盆地沉积建造特征、燕山中晚期构造特征和喜山期构造特征的分析,简述了鸡西盆地盖层构造特征。
Lower Cretaceous rifting in Jixi Coal Basin,close by the DunMi（Dunhua-Mishan）fracture control,in the Late Early Cretaceous,uplift around the basin,in the late Yanshanian,the District Mainly to faults and volcanic activity.in the Cenozoic,Jixi basin affected by the control of the new tectonic movement,DunMi fracture was active again.Himalayan movement formed PingMa（PingYang-Mashan） fault.This paper through analysed the sedimentary formation feature in Jixi Coal Basin,the structural features of Mid Late Yanshanian period and the structural features of Himalayan period,briefly described structural characteristics of caprock in Jixi Coal Basin.
