| 摘 要： | 利用柯东地区最新采集的"宽线+大组合"地震剖面,结合地表露头和钻井资料,以柯东1号构造作为重点,对柯东构造带进行构造解析.新建的构造模型总体表现为由若干倾角不等的逆冲断层构成楔状叠瓦扇,其根部向南延伸收敛在基底卷入的高角度逆断层上,叠瓦扇前缘可能收敛在中生代和新生代地层接触界面上,发生滑脱形成薄皮逆冲构造.在逆冲叠瓦断层系统中,多个断块中发育有与断层相关的褶皱,形成了柯东构造带众多的圈闭.

| Abstract: | The newest seismic profile of wide line and large array in Kedong area is used to interpret Kedong structural belt,taking the KD-1 trap as an example,combining with the study on outcrop and drilling data.The new structural model is an imbricate structure made up of thrust fault blocks with different dips.The root of the fault blocks is extending toward the south and convergent on the reverse fault with steep basement.The frontal of the imbricate structure may be convergent on the contact interface between t... |
