谢家沟金矿是胶东地区新发现的大型金矿床,矿床类型为“焦家式”与“玲珑式”的过渡类型。对矿床3种主要矿石类型、不同中段的22个矿石样品进行了黄铁矿热电性测试,结果表明黄铁矿以N型导电为主,早期形成的黄铁绢英岩中黄铁矿热电系数最大,主成矿阶段形成的黄铁矿—黄铜矿绢英岩次之,晚期的黄铁矿—黄铜矿石英脉最小;从+130m中段到+242m中段,N型黄铁矿的出现率逐渐变小,热电系数也随之下降,认为矿体的浅部已被剥蚀,N型黄铁矿出现率表现较好的连续性说明深部资源潜力很大。
The Xiejiagou gold deposit is a newly discovered large-scale gold deposit in the Jiaodong area. The deposit type is the transitional type of “Jiaojia” and “Delicate”. Pyrite thermodynamic test was carried out on 22 ore samples from 3 major ore types and in different middle stages of the ore deposit. The results show that the pyrite is mainly N-type, the pyroelectric coefficient of pyrite in the early formed pyrites is the largest, Followed by pyrite-chalcopyrite-sericite formed in the main metallogenic stage, while the late pyrite-chalcopyrite vein is the smallest. From the middle of + 130m to the middle of +242m, the occurrence of N-type pyrite gradually Smaller, and the thermoelectric coefficient also decreases. It is considered that the shallow part of the ore body has been denuded and the continuity of the occurrence of N-type pyrite shows the great potential of deep resources.
