| 摘 要： | 广西铜矿床成矿与岩浆活动关系密切。根据矿床成因主要有岩浆热液型、沉积-热液改造型及沉积型等。根据物质来源及囤岩特征可分为矽卡岩型、斑岩型、云英岩型及铁镁岩型等四种矿床模型。通过对广西主要铜矿床地质特征及成矿条件研究，指出大明山地区、岑溪-博白拗陷带、丹池地区等7处是寻找铜及多金属矿产有利地区。

| Abstract: | The ore-forming process for copper deposits in Guangxi is closely related to magma movements. According to genesis of deposits, there are different mineralization types in this area with the major ones of magmatic-hydrothermal deposits, sedimentary-hydrothermal alteration deposits, sedimentary deposits and so on; whereas based on the matters sources and characteristics of wall rocks, there are four types of deposits would be found here, including skarn-host deposits, porphyry-host deposits, greisen-host deposits and mafic rocks-host deposits etc. After studying the geological characteristics and ore-forming conditions of major copper deposits in Guangxi, it has pointed out 7 areas including Damingshan domain, Cenxi-Bobai depression zone and Danchi area etc. as favorable areas for detecting copper and polymetallic deposits. |
