| 摘 要： | 以岩浆期后热液交代充填成矿为特征的广东潮安四望坪铜矿床,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。通过对矿区地质环境与矿床成因的深入分析,建立了火山期后热液矿床的控矿模型,为粤东火山岩地区继续寻找该类矿床提供了启示。

| Abstract: | Siwangping copper deposit is a typical magmatic hydrothermal metasomatic-backfilling ore deposit in Chaoan county,eastern Guangdong province,whose most important ore-controlling factors are magmatic rocks,faults or interlayer sliding fracture,and wallrock feature,meanwhile interlayer sliding fracture in rhyolite porphyry and crystal tuff are the most favorable space for mineralization.The comprehensive analyzing of the relationship among magmatic rocks,fault,wall rock condition and ore-body scale or enrichment style are used for explain the genesis of this deposit.Furthermore,metallogenic modal is established,which is useful for the further prospecting for the similar ore deposits in this area. |
