摘要
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。
It is found that there occur varlous gold-bearing and arsenic-richy pyrite growth-bands.Their textures and structures, together with their occurrences and compositions, indicate that,during the main phase of ore deposition, gold has intimate geochemical relationship with arsenic and, in the developing process of arsenic-rich growth-bands, with the gold and arsenic depos it siWallaneously. which has possibly given the birth to invisible gold. This kind of growth-hands bears important minerogenic information. And therefore. it can be used to distinguish whether there occurred main-phase mineralization, at least, in the ore district.
