Metallogenic rules and directions for prospecting gold deposit in Hainan

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.
