Abstract
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.
