河南省嵩县九仗沟金矿床地质特征
|
摘要
九丈沟金矿区地处华北地台南缘、华熊台隆之外方山断隆区的西北部,属于熊耳山多金属成矿带的一部分。熊耳山成矿带是我国主要的黄金生产基地之一,该成矿带内生金矿床类型丰富,主要有构造蚀变岩型、石英脉型、爆破角砾岩型,其中以构造蚀变岩型为主,并伴生较强的铅锌矿化。
九仗沟金矿区内断裂构造发育,岩浆活动强烈,矿体呈脉状产出。九仗沟金矿具有明显的构造控矿特征,属构造蚀变岩型中低温热液矿床。主要控矿断裂为NNE向深大断裂F1。F1断裂是区域近东西向的马超营大断裂的次级构造,F1断裂集导矿、容矿构造于一体。构造活动主要分为三期:成矿前(形成热液运移通道)、成矿期(形成容矿场所)、成矿期后(形成破矿构造)。在空间上,金矿体受构造控制明显向NNW方向侧伏,侧伏角约60o。
矿床地球化学研究表明,成矿物质来源是多源的,岩浆热液-构造事件与矿床成因相关,在上述研究成果的基础上建立了矿源层-构造-岩浆“三位一体”的成矿模式。以控矿规律作指导,综合找矿标志和矿床地球化学特征,对矿体进行了定位预测。
Jiuzhanggou gold deposit is located in the Southern Margin of North China Platform and the northwest of Waifang mountain dislocated upwaringre ion of the huaxiong promontory, which is part of Xionger moutain polymetallic mineralization belt . Xionger moutain mineralization belt is one of the maior gold production bases in china, there are many types of endogenetic gold deposit,the main types are fractrue-altered rock type, quartz vein type, explosion breccia–type, the most important type is fractrue-altered rock type, associated strongly Pb-Zn mineralization.
Jiu Zhanggou gold deposit ,where fault construction develops, magma actives strongly. The orebodies occurs as veins.Jiu Zhanggou gold deposit has an obvious structural ore-controlling feature, which is a medium-low temprature hydrothermal ore deposit of fractrue-altered rock type.The most important ore-controlling fracture is the deep F1, F1 is NNE and is a sub-structure of Machaoying fault, which is nealy east-westward. F1 is not only ore-guided but also ore-containing. There are three active tectonics: Preminerlization (developing aise for hyrothmal fluid migrating), Mineralization (developing room for hosting ore), Miner- alition later (developing destroyed structure). In the space, gold ore-body controled by tectonic trends lateral to NE, the trending angle is 60°.
Mineralizing material source is multi-source,magmatic hydrothermal-tectonic events related to the genesis of deposit, based on the above-motioned researth result, building the“triplicity”metallogenic model of beds source-tectonic-magma. Under the guidance of the ore-controling rule,intergrating ore indicator and geochemical characteristic of deposit, forcasting the ore-body’s location prediction.
