Hainan Island contains abundant mineral resources and the metallogeny and mineralogenetic series on the island display many similarities to those in South China or the Nanling region but also have their own features.The best example is that the mineralization intensity of the Indosinian mineralogenetic series related to granitic magmatism is notably higher than that of the Yanshanian mineralogenetic series of the same type.In this paper,in light of the concept of the mineralogenetic series,the mineral deposits(occurrences) on Hainan Island are grouped into nine mineralogenetic series.The mineralization there occurred from the Neoproterozoic through Quaternary,and magmatism and weathering-sedimentation contributed most greatly to the formation of mineral deposits of commercial value.
