| 摘 要： | 桑树台断裂构造带位于梨树断陷西侧,为梨树断陷的控盆断裂。构造解析结果表明,桑树台断裂构造带自北而南由苏家屯断裂、桑树台断裂、南-北金山断裂组成,其间分别被西丁家侧接断裂和老公林子侧接断裂相连。火石岭期,在北西-南东向伸展环境下,桑树台断裂、北金山断裂和南金山断裂伸展活动强烈; 沙河子期,在左旋走滑构造环境下,桑树台断裂、北金山断裂和南金山断裂伸展活动强烈,断层间具调节转换性质的侧接断裂开始形成,同时苏家屯断裂开始活动; 营城期,在右旋走滑构造环境下,苏家屯断层和桑树台断裂北部伸展活动强烈,南金山断裂与老公林子断裂侧接带以南区域遭受挤压,缺失营城组沉积; 登娄库期-泉头早期,在左行走滑环境下,苏家屯断裂、皮家断裂、桑树台断裂、北金山断裂、南金山断裂及老公林子侧接带断裂强烈走滑,至泉头早期断裂活动显著减弱,几近停止,随后区域被巨厚的泉头组上部及上白垩统覆盖。嫩江期末期-明水期,在南东-北西向的挤压构造环境下,桑树台断裂带南段的老公林子断裂侧接带,走滑强烈,断层向上多切割至地表。喜马拉雅山期,桑树台断裂构造带无明显构造活动。

| Abstract: | Sangshutai fractures belt is in the western magin faul of Lishu fault depression,which consists of Sunjiatun fault,Xidingjia linkage fault,Sangshutai fault,Laosonglinzi linkage fault, north Jinshan fault and south Jinshan fault.In Huoshiling stage of Early Cretaceous,under the extensive environment of NW-SE,Sangshutai fault, north Jinshan fault and south Jinshan fault stretched intensely,and Sujiatun fault wasn't still active.In Shahezi stage of Early Cretaceous,Sangshutai fault, north Jinshan fault and south Jinshan fault stretched strongly,Laosonglinzi linkage fault between the above the faults was active,and Sujiatun fault also began to act,under the sinisterly strike-slip environment.Under the dextral strike-slip environment,Sujiatun fault and the northern part of Sangshutai fault were all extending strongly,the south Jinshan fault and Laosonglinzi linkage fault were in highly compression in Yingcheng stage of Early Cretaceous.From Denglouku stage to early Quantou stage,Sujiatun fault,Sangshutai fault,Jinshan fault and Laosonglinzi linkage fault were in transtensional strike-slip.This movement became weaker apparently and almost stopped in early Quntou stage of Early Cretaceous.So,it was covered by the thick upper Quantou Formation and Upper Cretaceous.From late Nenjiang stage to Mingshui stage,Laosonglinzi linkage fault slipped strongly and upperly cutted the Upper Cretaceous,under the NW-SE compression environment. |
