Abstract：In order to discuss the metallogenic regularity and deep prospecting potential of the Longmendian silver deposit in western Henan Province, on the basis of analyzing metallogenic geological background and ore geological features of the deposit, field geological survey, microthermometric survey of fluid inclusions, and geochemical survey of the deposit have been carried out in this paper. Results show that several metallogenic characteristics, including fracture-controlling, isometric distribution, and obvious side raking of orebodies, and wallrock alteration zoning, have been observed in the Longmendian silver deposit. They are very important indicative factors for the mineral exploration in the Longmendian area. Results of geochemical survey in the K6 orebody show that the primary halo zoning sequence of the indicator elements in axial direction from up to bottom of the K6 orebody is W-Cu-As-Hg-Mo-Au-Bi-Zn-Ag-Pb-Sb. This appears that there are obvious phenomenon of the co-existence of frontal halo and tail halo, and the reverse axial zoning. Combining with the variation regularities of geochemical parameters of trace elements in axial direction it is considered that there could be a quite large blind orebody in depth below the K6 orebody, especially, below the 848 m level. A drilling hole ZK6-01 has been designed to testify the predictive orebody at 620~640 m level.
