| 摘 要： | 在建立下扬子地区中生代地质事件序列的基础上，论证了大别山和下扬子地区印支期和燕山期存在两次相对独立的造山运动；并着重分析了下扬子地区燕山期出现大规模岩石减薄作用的过程，以及与之有关的大规模的成矿作用，并为区内开展深部找矿工作做了某些理论阐述。

| Abstract: | After sorting out Mesozoic geological events in the lower Yangtze area the authors suggested that there existed two relatively independent orogenic movements in the Dabieshan and lower Yangtze areas during the Indosinian and Yenshanian periods, especially the Yenshanian large-scaled lithospheric thinning process in the lower Yangtze area and the relevant mineralization. Comments are also made on deep-seated ore-prospecting work. |
