郯庐断裂带渤海湾北段早新生代逆冲推覆的生长褶皱证据
|
摘要
高分辨率的地震剖面显示辽河盆地西部凹陷深部存在一生长断层转折褶皱。本文对地震剖面的构造变形以及褶皱两翼的生长前、生长和生长后地层的变形几何关系进行详细构造解析;利用断层转折褶皱几何变形的计算机模拟技术分别对西部凹陷南段、北段的生长断层转折褶皱进行几何变形过程的模拟,提取构造特征并与实际地震反射剖面进行对比。研究结果表明,郯庐断裂带渤海湾北段分支断层台安-大洼断层在早新生代就存在逆冲推覆过程,构造活动主要发生在沙河街组三段下至馆陶组沉积前(E2s3下～N1g前),其逆冲推覆速率为0.116mm/a。
The high-resolution seismic profiles displays that a growth fault-bend fold occurs in the western depression of the Liaohe basin.This paper presents a detailed structural interpretation to seismic section , and then describes the deformed geometry related to the pre-growth strata , the growth strata and the postgrowth strata on both limbs of the fold.The computer geometric simulation , based on the model of faultbend fold , was utilized to stimulate the geometry of the growth fold in south and north segments of western depression.These structural features were subsequently extracted and compared with the actual seismic reflection section.Our research suggests that an overthrust formed during the early Cenozoic also appears in Taian-Dawa fault which is the northern section of Bohai breach in Tanlu fault zone.The event of structure mainly took place at the depositional stage between the lower three member of Shahejie and the former Guantao formations ( E 2 s 3L ～N 1 g ), with a thrusting rate of 0.116mm / a.
