摘要
对矿床微量元素的研究表明，矿区双桥山群地层和英安斑岩中，主要成矿元素Cu、AU、Pb、Zn等丰度很高，具有明显的富集，可以为矿床的形成提供足够的矿质来源。矿床的铜金矿化与铅锌矿化系不同的成矿阶段形成的，并存在矿化分带现象。在矿体中不同类型矿化伴生的微量元素存在着明显的差异，可以作为相应矿体的近矿指示元素。
tudy on minor elements in deposit indicates that 'main ore-forming elements are high inShuangqiaoshan Group stratum and dacite-potphyry and show enrichment indicating that theycan' provide enough ore materials during mineralizing process. The dePOist is characterized by Cu-Au, Pb^Zn mineralizations and ore zonation. The mineralhations were formed in different stagesand varied in minor elements which can be regarded as markers for the corresP0ndant ore bodies.
