| 摘 要： | 广东潮安四望坪铜矿以岩浆期后热液交代充填成矿为特征,在其三位一体（岩浆岩、断裂/层间滑动破碎带、围岩）的控矿组合中,以流纹斑岩、晶屑凝灰岩的层间滑动破碎带为最佳。本文从矿区资料的综合研究入手,深入剖析了岩浆岩、断裂、围岩圈闭条件与矿体规模、富集程度的关系;旨在通过对矿区地质环境与矿床成因的深入分析,建立火山期后热液矿床的断裂控矿模式,为粤东火山岩地区该类矿床的发现提供理论上的启示。

| Abstract: | Siwangping copper deposit in Chaoan county, Guangdong province, is characterized by post-magmatic hydrothermal metasomatism-filling mineralization. In the trinity orecontrolling assemblage （magmatic rocks, fracture/interlayer sliding fracture belts and surrounding rocks） of the deposit, the interlayer sliding fracture belts in rhyolite porphyries and crystal tuffs are the best ore-controlling factor. Starting with comprehensively studying the data of the deposit, the paper thoroughly analyzed magmatic rocks, fracture belts and trapping condition of surrounding rocks in relation to scale and enrichment degree of ore veins, being aimed to establish an ore-controlling fracture model of the post-volcanic hydrothermal deposit and to offer a theoretical guidance for prospecting deposits of this type in the volcanic rock areas of east Guangdong province basing on the thorough analysis on geological environment and genesis of the deposit. |
