| 摘 要： | 内蒙古新地沟金矿是中型绿岩型金矿床,但已属于严重资源危机的矿山,急待寻找接替资源,因此对新地沟金矿床进行深部远景预测具有十分重要的意义。本文根据找矿矿物学和成因矿物学理论,利用显微镜、电子探针及热电仪系统分析新地沟金矿床不同标高和矿段中黄铁矿的热电型标型特征,研究结果表明:新地沟金矿床中黄铁矿的晶型以立方体、五角十二面体及聚形为主;热电系数变化主要集中在-331.10~340.20μV·°C~(-1)范围内,导电型多以N型为主,约占总含量的80%;成矿温度主要集中于250~340℃,属于中温矿床。黄铁矿热电性参数XNP变化范围较大,估算矿体剥蚀率为67.96%~74.31%。通过对黄铁矿导型的空间分布规律和矿体剥蚀分析表明:油篓沟矿段位于矿体中底部,向深部可能有小规模延伸,小西沟矿段钻孔ZK106在深部有较大规模的延伸,其矿化前景最好;小西沟矿段钻孔ZK102深部矿化前景次之;大汗青矿段钻孔ZK_2802其深部矿化前景较差。综合分析认为,该矿床深部具有较好的找矿潜力。
