摘要
赣东北地区位于扬子、华夏两大构造单元复合部位,中、新生代受到北北东向滨西太平洋构造--成矿域强烈叠加作用,成矿地质条件优越、成矿期次多、成矿强度大、矿床类型多样。近年来区内找矿工作有了新突破,对内生金属矿床区域成矿规律的认识也有了新的进展。对照其大地构造单元笔者将赣东北地区划分成2个成矿带,7个成矿亚带,总结了4个主要成矿期,归纳出4大主要成矿系列,构建了区域矿床成矿谱系。
The northeastern Jiangxi is located in the composite part between the Yangtze and Cathaysia tectonic belts,and strongly overprinted by the Mesozoic and lenozoic NNE-stretching circum-Pacific tectonic metallogenic domain,which favored this area,in ore-forming condition,including multi-stages and high-intensity ore-forming with various types of deposit.Recently,a number of promising ores were discovered in this area and the regional metallogenic regularity has been achieved in recognization,particularly in the endogenous metallic deposit.According to the tectonic framework,the authors divided the northeastern Jiangxi area into 2 metallogenic zones and 7 metallogenic sub-zones,and summarized 4 main metallogenic events with 4 main metallogenic series.The regional mineralizing pedigree of ore deposits is recognized also.
