The Huanglongpu molybdenum ore field,situated in the western region of the East Qinling metallo-genic belt on the southern margin of the North China block,represents the only concentration area of carbonatite-type molybdenum deposits worldwide,and spatially controlled by the Lushi-Machaoying fault.On the basis of previous research results,This study presents a systematic sorting and comprehensive analysis of the regional geological setting,metallogenic characteristics and typical deposits of the Huanglongpu ore field.The formation of carbonate vein-type molybdenum deposits is closely related to the magmatic activities during the Indosinian period,with the favorable structural framework providing ore-bearing spaces and the surrounding rocks con-tributing trace ore-forming materials.The study delineates two primary ore-forming belts,namely the NW-ori-ented Yuantou-Nianziping rhenium-molybdenum polymetallic ore(mineralization)belt and the NE-oriented Xiping-Qinlinggou molybdenum-copper ore(mineralization)belt,comprising two third-level ore-forming zones and two fourth-level ore-forming zones.The Re and Mo contents generally exhibit a positive correlation.The ore-forming fluid is mainly characterized as magmatic water from the medium-high temperature silicate-carbon-ate-sulfate system,with ore-forming materials predominantly derived from mantle-derived igneous magma dur-ing the late Indosinian period,and it has roughly gone through three main mineralization stages.This study con-ducts prospecting predictions from multiple perspectives,there are promising prospects for molybdenum prospecting in the northeastern end of the ore field extending toward Henan and on both sides of the Lushi-MaChaoying fault at the southwest end.Additionally,the Huayangchuan-Taiziping mineralization belt and the lower part of the rock mass in the northwest of the ore field hold potential for large and medium-sized molybde-num polymetallic deposits.
