在秦岭取茶岭金矿床中发现了含金富砷黄铁矿增生环带。其产状、结构构造和成分恃征共同显示了，金成矿主期全与砷有密切的地球化学相关性，在富砷增生环带发育时，金与砷共沉淀．并可能在其中发育了不可见金。这种环带包含有重要的成矿作用信息，至少在矿区范围内可用于判别是否有主期矿化发育。
Gold-bearing arsenic-rich pyrite accretionary annulus was found in the Qindaling gold deposit in Qinling. Its occurrence, structure and composition indicate that the main gold mineralization was closely related to arsenic and geochemically, and gold and arsenic co-precipitated during the development of arsenic-rich hyperplastic zone. And may develop invisible gold among them. This zone contains important information on mineralization that can be used to determine if there is any major mineralization at least in the mining area.
