MAIN MINEROGENETIC SERIES AND METALLOGENIC CHARACTERISTICS ON HAINAN ISLAND

摘要: 海南岛蕴藏着丰富的矿产资源,其成矿规律、成矿系列与我国华南或南岭地区既有很多相似之处,也有自己的特色,如印支期与花岗岩浆活动有关的矿床成矿系列及其成矿强度明显高于燕山期同类型矿床成矿系列,就是一个最好的例证.本文按照成矿系列的学术思想,将海南岛的矿床(点)归并为9个矿床成矿系列,成矿时代从新元古代开始,一直到新生代第四纪.成矿作用方面,岩浆活动和风化-沉积作用对工业矿床的形成贡献最为有利.Abstract: 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.
