| 摘 要： | 近年来“矿源层”这一概念已被广大地质学家所接受，他们认为矿床中的金是从围岩中萃取的，本文认为矿床中的金来源于岩浆残余热液。在地壳深部，当丰度值高的基性岩或其他岩石，在深熔作用下产生花岗质岩浆时，同时带出许多金，当岩浆侵入到上部地壳冷凝结晶时，其中的大部金进入残余热液，最后富集成矿。 |

| Abstract: | Basing on the thorough collections and systematic studies of the geological reports of exploration,detailed investigation and ore spot inspection in gypsum mining areas,and the drilling dada from the reports of coal fields,bauxite,petroleum,the authors considered that the main minerogenetic epoch of gypsum in Shanxi is Middle Ordovician According to the analysis of gypsum bearing horizon space distribution,lithologic characters,petrofacies and sedimentary environment,the genesis of gypsum is also discussed |
| Keywords: | Middle Ordovician gypsum Shanxi province |
