Normal>The Hainan Island lies in the circum-Pacific tectonomagmatic metallogenic belt. Petrographic and isotopic studies indicate that the Hercynian-Indochinese granitoids in the Hainan Island may be divided into S-type and I-type. The granitoids in the Yenshan epoch is I-type. Multiple emplacement of granitic magma resulted in various ore fluids and ore matters. The ore-forming perspective regions related to the granitoids in the Hainan Island are divided by the DPIS metallogenic prognosis system.
