An integrated ore-prospecting method and model in search for Shuangshan alkali syenite Nb deposit in Fangcheng County,Henan Province

In this paper,an integrated ore-porspecting method is put forward in search for alkali syenite type"rare metal and REE" ore deposits. The method includes finding prospecting target through stream sediment survey,delineating the mineralized zone by rock sur-vey,the performance of geological mapping of characteristic minerals to find the ore-bearing geological bodies,the control of the surface orebody by trench and the verification of the deep orebody by drilling. The combination of these techniques for ore-prospecting is eco-nomical,rapid and efficient in practice. Based on analysis and study of various prospecting techniques,the authors have built a pros-pecting model,which has guiding significance in search for alkali syenite type Nb-REE polymetallic deposits in China.
