| 摘 要： | 冀中坳陷中生代构造变形主要包括印支期古亚洲域的北西西向和燕山期环太平洋域的北东、北北东向压性构造及其配套的北西向张性构造。前者主要是残存的徐水─任丘古隆起带，次要则如留西─大王庄古隆起带等；后者除了北东向的高阳─无极隆起带以外，则以同向的断裂构造为主。西界为太行山东伸展断层，而东界为 (古 )马西逆冲断层和 (古 )里坦逆冲断层以及 (古 )宁晋逆冲断层、 (古 )新河逆冲断层等构成叠瓦状逆冲系统。古亚洲域向环太平洋域的转换时期在中侏罗─早白垩世之间。中生代构造研究可以为冀中坳陷深层油气提供潜山圈闭、下第三系披覆背斜圈闭和岩性圈闭等有利勘探目标。

| Abstract: | The seismic and stratigraphic data on the Jizhong basin have been analysed to determine the tectonic deformation and evolution during the Mesozoic.Early stage (Triassic) of evolution of the basin is marked by WNW－ striking compressive structures,where mainly preserved,named Xushui－ Renqiu ridge and Liuxi－ Dawangzhuang ridge during Indosinian movement. The following stages (from Jurassic to Cretaceous) are marked by NE－ NNE－ striking compressive structures and NW－ striking extended structures during Yanshan movement.More of the NE－ NNE－ striking compressive structures are faults except Gaoyang－ Wuji ridge.The faults mainly included East Taihang mountain normal fault in the west and Maxi thrust,Litan thrust,Ningjing thrust and Xinhe thrust in the east.The latter composed of nappe system during Yanshan movement.The transitional period is between the middle Jurassic and the early Cretaceous and represents a tectonic transition from proto－ Asia tectonic tract (PATT) to circum－ Pacific tectonic tract (RPTT).Therefore,the promising traps during the Mesozoic for hydrocarbon exploration are buried hills and drape anticline traps associated with NW－ striking extended structures. |
