摘要 通过研究前河金矿黄铁矿的热电性和热爆特征,探讨了成矿温度、矿体规模、成矿阶段等方面的信息,并应用矿物学填图法对该区的深部找矿远景进行了预测。研究结果表明,该矿床形成温度为222.3~360.1℃,为一中温矿床,各中段黄铁矿导型均以N型为主,总含量达81.4%,矿体剥蚀程度在空间上存在高—低—高式的韵律特征,表明金矿体在200m中段至520m中段产出稳定,往深部有延续的趋势;黄铁矿的热爆峰主要有3种类型,分别对应早、中、晚3个成矿阶段。 The authors discuss the ore-forming temperatures, orebody size and mineralization stages of the Qianhe gold deposit by using the thermoelectricity and decrepitation temperatures of pyrite fiom the deposit and evaluate the ore prospects at depths in the ore district by using mineralogical mapping. The study results show that the ore-forming temperatures of the deposit range from 222.3 to 360.1℃, indicating that the deposit is a mesothennal one. The thermoelectric properties of pyrite in all the levels are of the N type, with the total content reaching 81.4%. Spatially, the degree of erosion of the orebody shows the rhythinic feature, i.e. being from high to low and again to high, which indicates that the gold orebody is persistent form the 200 to 520 m levels and has a tendency to continue downward. There are mainly three types of decrepitation peak for pyrite, which correspond to the early, middle and late mineralization stages respectively.
