摘要：

渤海湾盆地黄骅坳陷奥陶系潜山可划分为3种类型:1)翘倾断块潜山,是在喜山期扭张运动中发育的翘倾断块,其形成与伸展作用有关,如徐黑、北大港和南大港潜山等;2)层滑冲断潜山,与寒武系内部存在的滑脱断层或盲冲断层有关,一般发育在断块的内部,燕山早期形成,如千米桥、孔西潜山以及发育在徐黑翘倾断块内部的潜山等;3)背斜潜山,可分为挤压背斜潜山和滚动背斜潜山,前者是在燕山早期扭压过程中形成的挤压背斜潜山如乌马营潜山,后者是在沧东断层伸展中上盘发育的滚动背斜潜山如孔店、王官屯潜山等。翘倾断块潜山位于黄骅坳陷的东南侧和西北侧,与埕西断层和沧东断层的伸展活动有关;背斜潜山自北向南依次分布于中南区的孔店、军马站、王官屯和乌马营以及东光潜山等;层滑冲断潜山主要发育在翘倾断块内部,黄骅坳陷中南区的层滑冲断方向从东南指向西北,而北区的层滑冲断方向则从西北指向东南,呈左行扭压态势。

Abstract:

Three types of Ordovician carbonate buried-hills can be identified in Huanghua depression,Bohai Bay basin.(1)Tilting fault-block buried-hills were developed during Himalayan transtensional movement and their formation was related with extension faulting,such as Xuhei,North Dagang and South Dagang buried-hills.(2)Bedding slip and thrust buried-hills were generally developed within fauh-blocks during the early Yanshanian and were related with the detachment faults and blind thrust faults within the Cambrian strata,such as Qianmiqiao and Kongxi buriedhills,as well as those developed within the Xuhei tilting fault-block.(3)Anticline buried-hills can be further divided into compressional anticline buried-hills and rollover anticline buried-hills,the former were formed during the transpression movement in early Yanshanian,such as Wumaying buried-hill,while the latter were developed in the hanging wall during the extension of Cangdong fault,such as Kongdian and Wangguantun buried-hills.The tilting fault-block buried-hills are distributed in the southeastern and northwestern parts of Huanghua depression,and are related to the extensional movements of Chengxi and Cangdong faults.The anticline buried-hills are distributed successively from north to south,including Kongdian,Junmazhan,Wangguantun and Wumaying,as well as Dongguang buried hills in south-central Huanghua depression.The detachment thrust buried-hills are mainly distributed within the tilting fault-blocks.The detachment thrusts are directed from SE to NW in south-central Huanghua depression, while those in the north are directed from NW to SE in sinistral transpression state.
