广东揭西金坑铜锡铅锌矿床构造控矿特征与找矿意义
|
摘要
广东揭西金坑铜锡铅锌矿床位于惠阳—梅县新华夏构造带之莲花山深大断裂带内。为探讨该矿床的构造控矿特征,通过综合分析野外地质现象及原始资料,认为该矿床具有矿化范围广、规模大、矿脉发育、金属矿物品位变化大的特征;具有断层控矿及动力变质带控矿的构造控矿特征,马山区段北北东—北东向断层及崆角区段产于岩体中的北西向小断层是研究区的容矿构造,北东向动力变质带为该区主要的控矿构造。莲花山深断裂带内其他矿床(点)均具有"金坑式"矿床的找矿潜力。
The Jinkeng copper-tin-lead-zinc deposit in Jiexi County of Guangdong Province is located in the deep Lianhuashan fracture zone of the Huiyang-Meixian County Neochathaysian structural belt. In order to investigate the characteristic of ore-controlling structures of the deposit,this work conducted a comprehensive analysis of various field geological phenomena and first-hand data. It is found that this deposit is featured by its wide mineralization range and large scale,well-developed ore veins,and greatly varied grades of metal minerals. It has the characteristic of fault ore-controlling structures and dynamic metamorphic belt. The NNE-NE-trending faults in the Mashan section and the NW-trending small fault occurred in rock bodies in the Kongjiao block are ore-hosting structures in the study area,and the NE-trending dynamic metamorphic belt is the main ore-controlling structure. Other ore deposits or spots along the deep Lianhuashan fault belt all have a potential for prospecting ″Jinkeng-type″ deposits.
