上扬子地台区超晚期断褶构造与油气及金属矿产资源

THE LATEST FAULTFOLD STRUCTURE AND RELATIVE PETROLEUM AND METALLIC MINERAL RESOURCES IN THE UPPER YANGTZE PLATFORM

上扬子地台区长期接受地台型沉积，地壳构造较稳定。但自喜马拉雅运动以来，断褶构造活动强烈。按上扬子地台区超晚期断褶构造发育程度，可划分为５个构造区。超晚期断褶构造发育程度控制了上扬子地台区油气藏及金属矿产资源的形成与分布。应用超晚期断褶构造分区的观点，可预测上扬子地台区金属矿产资源及含油气远景。

The Upper Yangtze platform received platformtype sediments for a long period of time. There the crustal structure was relatively stable, but folding and faulting have been intense since the Himalayan movement. According to the development degrees of the latest foldfault structures, five structural areas may be distinguished. The formation and distribution of the petroleum and metallic mineral resources in the study region were controlled by the degree of development of the latest foldfault structures. The metallic mineral resources and petroleum prospects in the Upper Yangtze platform may be predicted from the viewpoint of the division of the latest foldfault structures.
