Geological characteristics and ore-search prospect of the Weijia tungsten deposit in Nanling region

The Weijia tungsten deposit is another large-size tungsten deposit discovered recently during the new round of prospective survey for mineral resources on the northern margin of the Nanling Mountains.Based on a discussion on the metallogenic geological background,the authors studied the geological characteristics of the ore deposit.The spatial distribution of the ore body is controlled by the basement structure,lithologic character,Xianglinpu anticline,Xianglinpu granite porphyry and the concealed rock body resulting from the NE-trending intrusion of the Tongshanling granite porphyry.The secondary emplacement of the magma caused the secondary mineralization.The ore deposit is of porphyry-skarn type.In this paper,ore-prospecting criteria are pointed out,and oresearch prospects as well as direction for further work are analyzed,which is of some guiding significance for ore-prospecting work in the future.
