实际资料分析表明,同一级河谷的砂矿,当砂矿原生源的侵蚀断面相近及成矿后的大地构造-地貌和古地理条件相同时,在不同类型构造中其主要参数是完全不同的。这些参数相互间明显相关。根据结构的特点及大地构造的发育,可以划分出四种具有相近参数的砂金区成矿类型(表):Ⅰ.冒地槽发育的褶皱区;Ⅱ.构造岩浆活化带(结晶地质,可能还有台背斜和残留地块);Ⅲ.优地槽发育的褶皱区;Ⅳ.火山带。
The actual data analysis shows that the main parameters of sandstone in the same river valley are completely different in different types of structures when the eroded sections of the original sand source are similar and the geotectonic-paleogeographic conditions after mineralization are the same. These parameters are clearly related to each other. According to the characteristics of the structure and the development of the tectonic tectonics, four types of gold deposits with similar parameters can be divided into four types: (1) folds with developed troughs, (2) tectonic magmatic activation zones There are sets of anticline and residual block); Ⅲ. Well developed trough fold zone; Ⅳ volcanic zone.
