Abstract: Through 1 ∶50 000 stream sediment survey in Getiaoping area in Luanchuan County,Henan Province,the distribution pattern,enrichment and dispersion of main ore-forming elements were summarized. It was found that there were local enrichment phenomena of Mo,W,Au,Ag,Cu,Pb,Zn and other ore-forming elements,especially the enrichment coefficient (K) of Mo element was the highest (1. 53) in the whole area. On the basis of comprehensive analysis of regional metallogenic geological conditions,1 ∶10 000 soil geochemical survey was deployed to the optimal AS-33 comprehensive anomaly. The Mo anomaly has good recurrence,and is associated with W,Cu and other elements combination,showing horizontal zonation phenomenon,and has the characteristics of hydrothermal Mo anomaly. Through trough exploration,12 molybdenum ore bodies,1 tungsten ore body and 4 tungsten mineralized bodies have been ringed,and good prospecting results have been obtained. Based on the above analysis results,the comprehensive prospecting model of molybdenum ore is established,and five prospecting targets of tungsten,molybdenum,lead and zinc polymetallic ore are delineated. It has certain reference value for the prospecting of molybdenum and tungsten ore in Luanchuan area.
