| 摘 要： | 和阳金矿的控矿条件分为地岩层条件、岩浆岩和构造条件。地岩层主要为南华纪的南沱组上部的含砾沉凝灰岩及中部的含白云质的大理岩央碳质泥页岩;岩浆岩为中酸性的脉岩;构造条件主要为挤压剪切产生构造劈理化带和三组节理,节理内充填有石英细脉,表现为网脉状的石英细脉控矿容矿。通过对矿区内几条探槽内发育的石英脉体的统计,分析局部的应力场特征。结合区域构造资料,探讨矿区的控矿条件特征,进一步开展找矿工作。

| Abstract: | Ore-control conditions of the Heyang gold ore deposit involve in rock-stratigraphy,igneous rocks and structures.The rock strata mainly include gravel-bearing sedimentary tuff in the upper part of the Nantuo Formation of the Nanhua System and dolomitic marble intercalated with carbonaceous argillutite in the middle part of it,the igneous rocks are mainly intermediate and acid veinlets,and the structures are substantially cleavage zones due to compressive shearing and three groups of joints,in which quartz veinlets are filled, showing that ore control and host are achieved through network quartz veinlets.Local stress field features are analyzed on the basis of statistics of quartz veinlets developed in a couple of explorative pits in the area.With regional structural data being taken into consideration, the authors discussed the features of ore-control conditions for furthering ore-prospecting work in the area. |
