摘要
六梅金矿床位于广西贵港市龙山矿田福六岭金矿区,属于卡林型金矿床,矿体呈脉状分布。对矿山已开采中段系统采样,进行原生晕研究。矿床元素的空间分布规律显示六梅金矿床中Au、As为正相关关系,含量等值线在空间上吻合性良好,As可作为Au找矿的主要指示元素。原生晕轴向垂直分带序列自上而下为:Cu-Zn-Pb-Hg-Mo-W-Au-As-Ag-Bi-Sb,为"反分带"序列,显示出该金矿床具有多期次多阶段叠加成矿成晕的特点。根据矿床原生晕地球化学特征预测深部矿化的存在。
Liumei gold deposit is located in Fuliuling gold mining district of Longshan mine field in Guigang,Guangxi,which belongs to carlin type gold deposit occurring as veins.In order to illuminate the primary halo,samples of the exploited section in the deposit have been collected systematically.The distribution of element in space indicate that Au is closely related to As,and the contour shapes of Au and As are very similar.The element As can be seen as the main Au indicator.The axial zoning sequence of the primary halo is Cu-Zn-Pb-Hg-Mo-W-Au-As-Ag-Bi-Sb,as an ＂anti-sub belt＂ sequence,which reveals the characteristic of ore-forming and halo-forming processes of the gold deposit with several metallogenic stages.According to the geochemical characteristics of primary halo of Liumei gold deposit,the existence of deep mineralization have been predicted.
