Abstract: The Shikou gold deposit, a newly discovered gold deposit with prospect potential, is tectonically located in Qinzhou-Hangzhou metallogenic belt. In order to further expand the prospecting results, this paper analysis the primary halo characteristics of orebody No.Ⅲ-②, and discusses the prospecting potential of the Shikou gold deposit in combination of the results of soil geochemical measurement,. The research results show that:(1) As, Ag and Sb are strongly related to Au which is the main metallogenic element. F is a typical indicator element in this region; (2) the mineralization of orebody No.Ⅲ-② might have experienced multiple-stage superposition, and the rear halo elements appears in the front of axial zoning sequence of the primary dispersion halo, which indicate certain metallogenic potential in deep area. The authors hold that there might be a further ore-prospecting space along the strike of the ore section Ⅲ and in the deep of orebody No.Ⅲ-②.
