摘要
燕山期火山-次火山-浅成斑岩金矿成矿系列构成了赣北地区一个重要的金矿成矿系列.根据其金矿成矿物质来源、成矿作用及产出的围岩条件可划分为火山热液型、次火山-浅成斑岩热液型和隐爆角砾岩型金矿床.对上述3种主要金矿床地质特征、找矿标志进行了较为详细的描述,同时对赣北地区该金矿成矿系列进一步找矿方向进行了论述,旨在加强和推动赣北地区金矿地质勘查工作.
The gold deposits, related to volcanic-subvolcanic-porphyry metallogenic series of Yanshan epoch in Northern Jiangxi Province, belong to one of the most important gold metallogenic series. Based on the derivation of metallogenic matters, mineralization and wallrock conditions, the gold deposits are subdivided into three main types： volcanic thermal type, subvolcanic rock-shallow to ultra-shallow porphyry thermal type, and concealed explosive breccia type of gold deposits. In order to promote and guide the prospecting of gold in Northern Jiangxi Province, the authors discuss the geological features, criteria and directions for ore-prospecting.
