通过矿物地球化学研究 ,认为陕西二台子铜金矿床属钠长石碳酸角砾岩型矿床 ,是大陆热点成矿系统中幔源碱性热流体成岩成矿作用多期叠加所形成。砷黝铜矿富Fe、As,低Sb、Ag ;黄铁矿中富As、Se,白云石 (内核 )有显著的锰铁白云石 (外部环带 )增生环带 ;长石类矿物出现富Mg铁长石 ;这些特征是陕西二台子铜金矿床属钠长石碳酸角砾岩型矿床的典型矿物地球化学特征。矿物地球化学组合类型指标可判断不同矿化类型及分散矿化 ,矿区外围半仓沟有较大的找矿前景。
Based on mineralogical and geochemical studies, it is believed that the Ertaizi gold-gold deposit in Shaanxi is a breccia-type breccia-type albite deposit formed by multi-stage superposition of diagenetic and mineralizing processes of the mantle source alkaline hydrothermal fluids in the continental hot metallogenic system. The arsenic-tetrahedrite is rich in Fe, As, low Sb and Ag. The As, Se and dolomite (pyrite) in pyrite have significant Mn-Fe dolomite (outer annulus) These features are typical mineralogical and geochemical characteristics of the albitite carbonate breccia deposits in the Ertaizi copper-gold deposit in Shaanxi Province. Mineral geochemical combination of type indicators can determine the different types of mineralization and decentralized mineralization, semi-trench outside the mining area has a larger prospecting prospect.
