北祁连地区新构造运动与成矿作用

Neotectonic movement and mineralization of the North Qilian area

北祁连地区是我国一个重要的构造成矿带,蕴藏着丰富的矿产资源。笔者通过对北祁连山地区新构造运动特征的研究,认为喜马拉雅运动以来的新构造运动不仅造成本区的强烈隆升、断裂褶皱构造的复活和产生,而且也影响着全区地貌、气候的形成与演化,还对北祁连地区的砂金、铂等金属矿床、油气田和非金属矿床的成矿作用以及分布都起着重要的控制作用。

The North Qilian area is one of the most important tectono-mineralized belts in which there are rich mineral resources in China. Based on studying the characteristics of neotectonic movements of the North Qilian area , the authors believe that the neotectonic movements since Himalaya movements not only made the North Qilian area intensive uplifting, and the recurrence and generation of faults and folds, but also brought about the formation and evolution of the surface feature and climate. Therefore, the neotectonic movements is an important controled factor on the mineralization and distribution of metallic ore deposit of the alluvial gold-platinum placer, oil and gas fields and nonmetallic.
