The Primary Halo and Deep Prospection of Liumei Gold Deposit in Guigang,Guangxi

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.
