马来西亚吉兰丹SOKOR金矿地质特征及成因浅析
|
摘要
马来半岛金矿主要分布在半岛中央金矿带北部,该成矿带地处特提斯成矿带与环太平洋成矿带交汇处,成矿条件优越。含矿岩石主要是千枚岩及石英斑岩,矿物以黄铁矿为主,矿体产状与接触带产状基本一致,金矿化类型主要有含金块状硫化物型、含金石英脉型及褐铁矿型3种,品位变化较大。矿床地质特征、矿体产状及矿化蚀变信息表明成矿与热液活动紧密相关,应属于浅成低温热液型金矿。
The Malay Pennisula gold mines are mainly distributed in the north of the central gold belt of the peninsula,and the metallogenic belt is located at the junction of the Tethys metallogenic belt and the Pacific Rim metallogenic belt,and the metallogenic conditions are superior. The main ore bearing rocks are phyllite and quartz porphyry,the main ore minerals are pyrite,orebody occurrences are consistent with formation occurrences of contact zones. Gold mineralization types are mainly massive sulfide type,quartz vein type and limonite type,and ore grade changes greatly. Geological characteristics,ore occurrences and alteration information show that mineralization is closely related with hydrothermal activity,and it belongs to the epithermal gold deposit.
