Abstract

The Tudiling large-sized Ta-Nb deposit was recently discovered in the South Qinling orogenic belt by the Hubei Geological Survey Institute. This paper introduces the methods used during the exploration process, and proposes a comprehensive prospecting method suitable for volcanic type "rare" deposits, that is, to find the target area by 1:50,000 stream sediment survey, to delineate the mineralized zone by large-scale rock profiling, to identify the ore-bearing geological bodies by mapping of volcanic lithofacies and rock combination characteristics, to constrain the surface orebodies by trenching engineering, and to verify the deep orebodies by drilling. Practice has proved that the combination of prospecting methods is economical, fast, and effective. Based on the analysis of various prospecting methods, a prospecting model is established, which is of great significance for prospecting of volcanic Ta-Nb deposits in China.

Key words： volcanic type Nb-Ta deposit integrated ore-prospecting method ore-prospecting model
