    Characteristics of Biotite in the Granite Porphyry and Its Significance for Petrogenesis and Mineralization of Dachang Sn-Polymetallic Ore Deposit, Guangxi

    • 摘要: 广西大厂锡多金属矿床是世界上最大的锡多金属矿床之一,区内花岗斑岩主要分布于铜坑-长坡-巴里-龙头山矿区的东侧,受近SN向张扭性断裂构造控制,并对早期形成的矿体产生了叠加改造作用.为了探讨花岗斑岩的成岩成矿条件,对花岗斑岩中以斑晶、包体以及基质形式产出的黑云母进行了详细的电子探针分析.结果显示:花岗斑岩中的黑云母主要为岩浆成因的铁质黑云母,且指示岩体具有高碱度的特征.与斑晶和包体黑云母相比,基质黑云母相对富铁、锰、锂,贫镁、钛.斑晶和包体黑云母结晶温度为688~715℃,结晶压力为1.7~2.3 kbar,相当于6.3~8.4 km的侵位深度;基质黑云母的结晶温度为630~673℃,结晶压力为1.6~2.0 kbar,相当于6.0~7.4 km的侵位深度.斑晶、包体和基质黑云母的氧逸度分别为-17.0~-16.1、-17.0~-16.6和-19.0~-17.4,指示在侵位的过程中,伴随着岩浆的上涌,氧逸度随之降低,成岩条件由相对氧化向相对还原的方向变化.与花岗斑岩有关的共存流体性质研究显示,斑晶黑云母中的lg(fH2O/fHFFluid、lg(fH2O/fHClFluid和lg(fHF/fHClFluid值分别为3.41~3.82、3.78~4.07和-0.54~-0.17;包体黑云母中的lg(fH2O/fHFFluid、lg(fH2O/fHClFluid和lg(fHF/fHClFluid值分别为3.90~4.11、3.86~4.11和-0.74~-0.43;基质黑云母中的lg(fH2O/fHFFluid、lg(fH2O/fHClFluid和lg(fHF/fHClFluid值分别为3.90~4.39、3.85~4.96和-0.61~0.25.结果显示,在花岗斑岩上侵的过程中,与不同阶段结晶生成的斑晶、包体和基质黑云母共存的流体在成分上有一定的差异性,不是单一的流体.大厂花岗斑岩中黑云母成分的变化指示岩浆结晶过程早期阶段具有高温、高碱度和低氧逸度的特征,有利Sn元素的活化、迁移、富集,进而对大厂锡多金属矿床起到叠加改造作用.
