摘要:

采用区域构造变形及应力场遥感图像分层解析法,利用遥感TM图像对研究区宏观构造及有关的横张大节理系统进行详细解译,结合物探资料并应用力学方法对区域构造变形场和应力场进行了计算与分析,建立了该区构造变形场和应力场的三维彩色定量解析模式图,通过综合分析研究,对该区构造组合的空间格局及其控矿(油气)规律进行了探讨。

Quantitative Analysis of Remote Sensing Images on Tectonic Deformation and Stress Fields, Southern Sichuan, China
Abstract:

Structural pattern on the remote sensing image is a synthetic result since geological history, including much feature information of previous tectonic deformation. Therefore, the tectonic stress fields of different stages in a complex deformation area can be reconstructed by the following steps: (1) Geological structures in different stage and time are decomposed with remote sensing images; (2) Tectonic deformation fields in different time are established by analyzing relationship between the micro structures (joints/fractures) and the macro tectonics (folds and faults) related; and (3) tectonic stress field in different time are respectively recovered with a synthetic study of the features of structural deformation fields in different periods.\;In this paper, macro tectonics (folds and faults) and related transverse tensional joint systems in the studied region are interpreted with the method of phase-separation analysis of remote sensing information field which was proposed by the author. Based on the theory of elastic mechanics, tectonic deformation and stress fields are quantitatively calculated, and 3-dimensional color structural block diagram for quantitatively analyzing tectonic deformation field and stress field are established. Finally, a relation of the structural patterns to the reserves of petroleum and natural gas are discussed.
