摘要
铜坑嶂钼矿床是目前南岭东段正在进行普查评价并取得重要进展的钼矿,它以独特的辉钼矿-萤石组合、特征的矿体内部结构变化趋势、辉钼矿颗粒大与品位富等宏观特征,有别于赣南已知的低品位斑岩型、与钨共(伴)生的石英脉型钼矿床。鉴于其产出的特定区域背景,通过Re-Os同位素研究,了解其成矿时代(134Ma),对研究其成矿机理及其在赣南燕山期区域性大规模成矿过程中的特殊性具有重要意义。
Tongkengzhang molybdenum deposit is located in East Nanling area. We have gotten lots of important progresses after primarily exploring. It has molybdenite-fluorite combination, special interior structure, big grain, and high grade. These characters are different from those low-grade molybdenum deposits, including porphyry and quartz-vein types. Through Re-Os dating, we know the mineralogenetic epoch （134Ma） that is significant to know how this deposit formed and how the large-scale mineralogenesis evolved at Yanshanian in South Jiangxi province.
