| 摘 要： | 大背坞金矿区及其外围前寒武系经历了三期构造变形：第一期形成近东西向障公山扇形复背斜及轴面流劈理；第二期形成北东向中常褶皱及轴面折劈理；第三期形成北东向挤压破碎带。第三期构造变形发生于700Ma左右。三期构造变形使围岩中分散的金富集形成三期含金石英脉。成矿受早元古代障公山群第五岩组矿源层、障公山复背斜西倾伏端、折劈理带、挤压破碎带复合控制。

| Abstract: | There are three Precambrian deformations in Dabeiwu gold deposif and its periphery. The first one is represented by nearly E-W Zhuanggongshan fan-shaped anticlinorium and axial plane flow cleavages; the second by north east-trend neutral folds and axial crenulation cleavage; and the third by compression shatter zones. The third deformation happened about 700Ma ago these deformations restlted in the gold scattered in rocks to be concentrated in quarts veins on three stares. The gold mineralisation is contrdled by source bed-the fifth rock formation of early Proterozoic Zhuanggong shan group, the west on plunge and of Zhuanggongshan anticlinorium, the crenulation cleavoge zwnes and the compression shatter zones. |
