ORE-CONTROLLING FACTORS AND GENESIS OF THE GOLD DEPOSITS IN THE ERJIA-BUMO GOLD BELT OF WESTERN HAINAN ISLAND
Abstract:The Erijia-Bumo gold belt is located in Changjiang and Dongfang Counties of western Hainan Island and is structurally situated on the Baoban rise of the Qiongzhong geosynclinal folded area. The gold belt stretched along the nor-east direction is composed of Tuwaishan, Baoban, Beiniu, Erjia and Bumo gold deposits. All of the gold deposits occur in favourable structural locations. They are long-term evolutional products of different geological functions under specified structual conditions.
