| 中文摘要: |
| 茅山金矿位于华北板块北缘中段,是遵化—青龙矿集区内赋存于二长花岗岩岩株内的金矿床。茅山金矿的金矿化主要产于茅山二长花岗岩岩株内的蚀变黄铁绢英岩内。文章对矿床的区域地质特征、矿化带及矿体分布、矿石结构构造、围岩蚀变、矿床成因诸方面进行了分析研究,认为该矿床的矿物成分和化学成分较复杂,矿床经历了多期次热液活动的叠加作用。成矿热液沿构造裂隙充填交代了围岩,使其发生了热液蚀变作用。矿床成因属中温热液裂隙充填交代矿床。 |
| 英文摘要: |
| The Maoshan gold deposit occurs in monzonitic granite in Zunhua- Qinglong gold mineralization concentration district located in the middle of the northern margin of North China plate. Based on integrated analysis of regional geological characteristics of the deposit, spatial distribution of mineralized zones and orebodies, ore texture and structure, wall rock alteration, genesis etc., it is concluded that the mineral composition and chemical composition of the deposit are complex, it indicated that the deposit has experienced superimposed effect of multi-stages hydrothermal activities. Mineralized hydrothermal filled along and replaced the surrounding rock along the tectonic fissures,which resulted in hydrothermal alteration. In all, the genesis of Maoshan gold deposit belongs to the mesothermal filling and replacement type deposit. |
