| 摘 要： | 花岗岩的多样性决定了对花岗岩成因的各种解释。对贺兰山中段黄旗口元古代地层中存在于花岗岩中“层理”、“残留体”等地质现象进行研究 ,认为该地区花岗岩是由元古代沉积岩经过变质交代作用而形成的 ,这种变质交代作用可能发生在古元古代 ,在秦祁贺三叉裂谷活动之前地壳变薄的大地构造环境下形成 |

| Abstract: | The diversity of granites resulted in various genetic explanations of granites. Based on the stu- dies of the “bedding” and “sedimentary relic” of granite in the Proterozic strata at Huangqikou of the middle part of Helanshan, the authors think that the Proterozoic granite in the area was produced by metasomatic metamorphism, which formed during the time when the earth crust became thinner. |
| Keywords: | Helanshan Ningxia Proterozic genesis of granite |
