| 摘 要： | 河南萑香洼金矿床作为典型的构造蚀变岩型金矿床,通过研究分析该矿床F985矿化带的Ⅰ号矿体各类元素组分在不同地质体的含量变化特征,原生晕异常分带特征和地球化学轴向分带特征,建立了该矿床完整的地球化学异常分带理想模型,得出矿床地球化学异常轴向分带序列确定为:烃类、Sb(前缘晕)→As、Hg(矿头)→(矿中晕)Au、Ag、Cu、Pb、Zn、W、Mn→(矿尾晕)Mo、Co、Ni、Sn,并总结出了找矿预测标志,为该矿区深部找矿提供了一定的科学理论依据。

Study on the geochemical zoning model of Huanxiangwa gold deposit in Henan |

| Abstract: | Huanxiangwa gold deposit in Henan Province is a typical tectonic altered rock type gold deposit.By studying the content variation characteristics of various elements in different geological body,the characteris-tics of primary halo anomaly zoning and geochemical axial zonation of trace elements and hydrocarbon to No.Ⅰorebody of 985 mineralizing zone,an ideal model for the geochemical anomaly of the deposit has been es-tablished.Its axial zoning sequence of geochemical anomalies is classified as follows:hydrocarbons and Sb show as geochemical front halo,As and Hg occur in geochemical head halo ,Au、Ag、Cu、Pb、Zn、W、Mn are middle halo and Mo、Co、Ni、Sn are enriched in trail halo.At the same time,the prospecting indicators of the deposit have been concluded.It will provide a scientific theoretical basis for the deep exploration of the mine in the future. |
