山东招远大伊格庄金矿烃类组分特征与异常模型研究

本论文以最新的烃汞综合气体测量集成技术结合部分传统有效的微量元素测量技术,依据已有的地质资料,以该矿床Ⅱ号矿体为研究对象,通过研究烃类组分和微量元素异常在矿床不同部位的展布规律、各指标异常在空间上与金矿体之间的对应关系,建立了矿床的地质地球化学综合找矿模型:烃类组分、As(前缘晕)→Cu、W(矿中晕)→Sb、Hg、Au、Bi、Pb、Zn、Ag、Mo(矿尾晕),并且总结了本研究区的找矿标志,为本区今后开展深部盲矿找矿预测提供了技术支撑.

Study on characteristics of hydrocarbon components and geochemical prospecting model for Dayin'gezhuang gold deposit in Zhaoyuanof Shangdong Province

In this paper,on base of analysis to the existing geological data,and using the hydrocarbon and mer-cury synthesis measurement and combined some parts of traditional effective trace elements measuring as the technique to study the distribution regularity of hydrocarbon and some trace elements anomalies in different part of the No.Ⅱorebody of DayinGezhuang ore deposit and the space corresponding relationship between different component anomaly and the gold body,the geochemical prospecting model of the deposit is estab-lished.That is:hydrocarbon components and As show as geochemical front halo-Cu,W show as the middle halo,and Sb,Hg,Au,Bi,Pb,Zn,Ag,Mo are in the trail halo.At the same time,the prospecting indications for study area are also summarized,and they will provide a scientific theoretical basis for the deep exploration of the mine in the future.
