中文摘要：

龙头山金矿是一个赋存于燕山晚期流纹斑岩间角砾岩带中的热液交代型矿床。研究了各微量元素和烃汞类组分在该矿床不同中段、地质体的含量变化特征以及在轴向上的展布特征,总结出龙头山金矿原生晕分带序列:烃类、Sb(矿前缘)→As(矿头)→Hg、Au、Ag、Pb(矿头至矿中上)→Cu、W、Mo、Zn(矿中下)→Mn、Ni、Ti、Co、V(矿尾)。该区成矿组分复杂,具有多期次脉动成矿的特征;根据成矿元素的分带规律,认为深部还存在金矿化体;建立了该矿床地球化学异常分带的理想模型,并总结出该区的找矿预测标志。

英文摘要：

Longtoushan gold deposit,a hydrothermal-metasomatic deposit,occurs at a breccia zone in rhyolitic porphyry of late Yanshanian.Based on the study of variety of axial distribution features of trace elements,hy-drocarbon and mercury gas in different levels and geological bodies,the zoning of primary halo has been summed up.It shows the exhibition feature of hydrocarbons,Sb (the longer forward part of ore body)→ As (the head part of ore body)→Hg,Au,Ag,Pb (the center to the upper part of ore body)→Cu,W,Mo, Zn (The lower part of ore body)→Mn,Ni,Ti,Co,V (the tail part of ore body).The ore-forming composi-tion is complex in this area.There are multi-stages of pulsation in metallogenesis.According to the zoning of ore-forming elements,it is possibleto find existence of gold ore bodies in depth at this area.An ideal mode for geochemical anomaly zoning is established,and the prospecting indications for exploration are summarized in Longtoushan gold deposit.
