铜矿属于我国重要的战略性矿产.广西铜矿具有分布广泛,矿床规模普遍较小,工作程度低,有较大找矿潜力的特点.在分析广西铜矿以往勘查和科研成果资料的基础上,总结广西铜矿成矿类型、成矿规律以及找矿方向.结果表明:广西铜矿成矿类型划分为岩浆热液型、浅成中—低温热液型、沉积型、接触交代型(矽卡岩型)、斑岩型等五种类型.广西铜矿成矿具有多期的特点,主要形成于四堡期、加里东期、印支期、燕山期及喜山期.提出九万大山—元宝山、德保钦甲、鹿寨—象州—金秀、大明山、海洋山—架桥岭、大吾—木梓、大姚等地区为广西铜矿找矿的主要方向.
The metallogenic types,metallogenic laws,and prospecting directions of copper deposits in Guangxi
Copper mines are an important strategic mineral resource in China.Copper mines in Guangxi are characterized by widespread distribution,generally small-scale deposits,low exploration degree,and signifi-cant potential for ore discovery.Based on the analysis of previous exploration and research results on Guan-gxi copper mines,this study summarizes the types of mineralization,mineralization laws,and prospecting directions for Guangxi copper mines.The results show that the types of Guangxi copper mines are divided in-to five categories:magmatic hydrothermal type,shallow-moderate low-temperature hydrothermal type,sed-imentary type,contact metasomatic type(skarn type),and porphyry type.The mineralization of Guangxi copper mines is characterized by multiple periods,mainly forming during the Sibao,Caledonian,Indosinian,Yanshanian,and Himalayan periods.The main prospecting directions for copper mines in Guangxi are pro-posed to be the Jiuzaoshan-Yuanbaoshan,Debao Qinjia,Luozhai-Xiangzhou-Jinxiu,Daming Mountain,Haiyangshan-Jiabridge Ridge,Dawu-Muzi,and Dayao areas.
