摘　　要：海南岛金矿资源丰富 ,岛内金矿分布主要受EW和NE向 2组区域性断裂控制 ,形成 2个EW向和 3个NE向成矿带。金矿类型可分为 1)产于深变质岩系中的金矿 ;2 )产于浅变质、强变形岩系中的金矿 ;3)产于碎屑岩中的金矿 ;4 )爆破角砾岩型金矿 ;5 )产于花岗质岩石中的金矿。规模大、经济价值高的金矿均受区内发育的剪切带控制 ,同时成矿具有明显的等距性、对应性 ,矿化在空间上具有明显的侧伏性 ;矿化蚀变强 ,硅化是直接的找矿标志。通过总结成矿规律和找矿标志 ,共划分出 5个成矿远景区 。Many gold deposits had been found in Hainan region. The distribution of gold deposits is controlled by two regional faults whose strikes are East west and Northeast, so there formed two East west and three Northeast metallogenic zones. The type of gold deposits can be divided into 1) gold deposit in deep metamorphic rock series; 2) gold deposit in shallow metamorphic and deep deformed rock series; 3) gold deposit in clastic rock; 4) gold deposit of explosion breccia type; 5) gold deposit in granitic rock. The large scale and high economic value gold deposits are controlled by shear zone, the metallogenesis has obvious equidistant and correspondence, the mineralization has obvious pitch in space, and had strong metallogenic alteration and silicification is the direct symbol of ore finding. By summarized the metallogenic rule and symbol metallization, five long range perspective region were put forward and evaluated tentatively.
