Abstract: In order to evaluate W-Mo resources objectively and comprehensively in Luanchuan，which is known as the molybdenum capital of China，this study re-delineated the W-Mo ore bodies by using the previous exploration data and the data of deep boreholes constructed in the area in recent years in Lengshui-Chitudian area，which located in the core area of Luanchuan ore concentration area.Meanwhile，the buried depth of the top interface of the ore-forming rocks inferred based on the high-precision gravity and magnetic data is corrected according to the holes.Based on the correction，the distribution characteristics and prospecting criteria of the main tungsten molybdenum ore bodies are constructed，and the distribution range of the tungsten molybdenum ore bodies at the top interface of the rock body in the mineralization period is calculated. Based on the corrected top interface of the rock body related to the Mo-W mineralization，combined with the metallogenic model of the molybdenum polymetallic depsoits in the area，the three-dimensional quantitative prediction is carried out.The study results show that molybdenum polymetallic ore in this area belongs to magmatic hydrothermal metallogenic system.The Mo （W） orebodies distributed in the inner and outer contact zone of the ore-forming rock body are controlled by intrusive interface.The ore-forming geological body is connected at a depth of 2 000 m.The molybdenum resources in Luanchuan mining area are predicted to be 14.48 million tons and WO3 4.25 million tons.According to the above prediction results，the further deep exploration rang of the area is further discussed.
