Abstract:The Jingcun gold deposit located in the Yunkai area, at the conjunction of Guangdong and Guangxi Province of South China and about 5 km away from the Hetai goldfield, is a major breakthrough in the periphery exploration of the Hetai goldfield in recent years, and has a medium size Au reserve. Similar to the deposit in the Hetai gold field, the ore body of the Jingcun gold deposit is strictly confined by ductile shear zones. However, the former is mainly hosted by the mylonitized Yunkai group migmatites, the latter by mylonitized and cataclastic granites. In order to guide the deep exploration, No. V1 orebody is selected for systematic primary halo zonation study. The results of multivariate statistics of 12 elements show that the deposit is likely a mesothermal to epithermal Au deposit, and elements Cu, As and Sb are the significant ore indicator elements showing notable positive correlation with Au. The primary halos axial zonation sequence of No4 exploration line from top to bottom is Pb- Bi- W- Mo- Ag- Cu- Hg- Zn- As- Sb- Ba- Au, showing reverse zonation. Moreover, the variation characteristics of geochemistry index in the deep, and the front and rear halos elements overlap and coexist at the bottom of No1 ore body, indicating a likely hidden ore body below -500 m altitude. According to the indicator elements geochemistry characteristics, the primary halos overlapping ideal model of No. V1 ore body is constructed.
