黑龙江三江盆地绥滨坳陷构造特征分析
|
摘要
以三江盆地绥滨坳陷为研究对象,采用构造-地层分析方法,通过选取5条地震剖面进行二维构造-地层解译,结果表明三江盆地绥滨坳陷同沉积期(城子河组,穆棱组,东山组)的盆地结构已经被后期逆冲作用改造;其内部断裂构造主要为北西向、北北西向,与北东向的隆坳结构相交,隆坳结构之后还发生了北东至南西向的挤压作用,从而导致绥滨坳陷内部发育的大量逆冲断裂。三江盆地西缘北东向断裂、南缘北西或北西西向断裂及东缘北东向断裂均在地震剖面上显示为正断层,虽然后期部分断裂发生了逆冲反转,但是它们控制了白垩系裂陷沉降与沉积;三江盆地在同沉积期遭受了2个方向伸展,即近南北向伸展和近东西向伸展;盆地东西两侧为依兰-伊通断裂和敦密断裂所限,三江盆地及北部的中阿穆尔盆地在早白垩世初期为右旋走滑伸展盆地;三江盆地西部主体剥蚀东山组之上的白垩系沉积,而东部上白垩统与东山组不整合接触,表明盆地在早白垩世初之后遭受了挤压和隆升剥蚀。
The structure and stratigraphy interpretation of five basin-wide 2D seismic profiles indicates that the syn-depositional framework of Suibin Sag in Sanjiang Basin was reshaped by later compression. The internal faults are mainly trending in NW and NNW, intersecting with the uplift-depression structure trending in NE. After the formation of uplift-depression structure, the basin was also undergone compression from northeast to southwest, resulting in a large number of reverse faults within Suibin Sag. Seismic interpretation reveals that Suibin Sag is bounded by normal faults to the west, south and east with trending in NE, NW/NWW, and NE respectively. These faults controlled the subsidence and deposition during Cretaceous, although some of them were converted to reverse faults later. Sanjiang Basin was undergone syn-depositional extension in all direction, i.e. the extension trending in N-S and W-E direction. The eastern and western boundaries of the basin are limited by Yilan-Yitong Fault and Dunhua-Mishan Fault, respectively. Sanjiang Basin and Amur basin to its north were right-lateral transtensional basins during early Cretaceous. The Cretaceous deposits above Dongshan Formation are missing in western Sanjiang Basin, while the eastern Dongshan Formation is unconformable with overlying Upper Cretaceous. These results indicate that the basin was undergone uplift and erosion due to tectonic reversion after Early Cretaceous.
