黔西六枝-大窑地区复合叠加褶皱及构造应力场遥感图像分层解析

贵州西部构造变形强烈，存在多组不同方位的褶皱及断层，各发育一套节理系，呈现为复杂的复合构造变形格局。本文应用“区域构造变形及应力场遥感图像分层解析新方法”，利用遥感图像对研究区宏观构造及有关的横张大节理系统进行了详细解译，建立了该区三期构造变形场，并据此反演了各时期构造应力场。

PHASE SEPARATION ANALYSIS OF REMOTE SENSING IMAGES OF COMPOUND SUPERPOSED FOLDS AND TECTONIC STRESS FIELDS IN LIUZHI DAYAO REGION, WESTERN GUIZHOU

In the Liuzhi Dayao region, western Guizhou, there are several groups of folds, faults and joint systems in different trends that form a complicated tectonic pattern. The mechanism of the tectogene in the studied area has been debated for a long time. In this study, using phase separation analysis method of remote sensing information fields, geological and structural features are systematically interpreted. Through an analysis of the combined folds, faults and related transverse tensional major joint systems , three periods of structural deformation fields are established. As a result, three periods of tectonic stress fields produced successively in the Yanshanian period are recovered.
