济阳坳陷负反转构造反转强度分析

he Intensity Analysis of Negative Inversion Structures in Jiyang Depression

中文摘要英文摘要

反转强度分析是反转构造研究的重要内容。反转强度定量分析的方法有反转率、位移-距离曲线等,但上述方法均不能适用于完全反转的反转构造。鉴于此,提出反转强度系数的概念,并应用于济阳坳陷负反转构造的研究中。结果表明,济阳坳陷各负反转构造的反转强度系数值介于1-7间,反转强度在平面上具有自北东向南西降低的趋势。反转强度与晚三叠世扬子板块活动产生的挤压应力场及早白垩世郯庐断层左旋活动产生的拉张应力场的特征密切相关。

he analysis of inversion intensity is the important part of the inversion structures study. The methods of characterizing quantitatively the inversion intensity conclude displacement- distance plot, inversion ratio and so on. But the methods can't characterize the complete inversion structures. So the inversion intensity coefficient is presents and applied to the study of negative inversion structures in Jiyang Depression. The results show that the inversion intensity coefficient of negative inversion structures in Jiyang Depression is between 1 and 7, and overall inversion intensity lowers from northeast to southwest. The inversion intensity are closely related to the characteristics of the compressive stress field which generated by the Yangtze plate's activity in the Late Triassic and the extensive stress field generated by sinistral strike-slipping of Tan-Lu Fault in the Early Cretaceous.
