Abstract: The Kafang Molybdenum mining area is located in the joint part of the North Qinling tectonic belt and the southern margin of the North China continental block and belongs to the polymetallic metallogenic belt of the East Qinling-Dabei Metallogenic Province.Based on the geological， mineral， geophysical and geochemical data in the mining area， the geological characteristics and prospecting potential of the mining area are studied.The results show that there is an anomalous combination of high-temperature elements （W， Mo， Bi） - medium and low temperature elements （Cu， Pb， Zn） - low temperature elements （Au， As， Ag） in the vicinity of the Laojunshan rock mass in the Kafang area.The high magnetic outliers in the mining area ranged from -300 to 120 nT， and there is a gradient zone with positive and negative anomalies in the south of the mining area.The resistivity logarithm of the surface in Luogou area of the mining area is measured as 0.8 ~ 1.2 at a depth of 500 m by magnetotelluric sounding （EH4）， which is inferred to be caused by mineralization， and the ore-bearing rock mass is found through the verification of drilling.Through systematic geological and mineral work， five molybdenum ore bodies in marble and quartz schist are found in the mining area.On this basis， two tungsten and molybdenum prospecting target areas are delineated in the Karfang area and metallogenic prediction is carried out.It is considered that the target areas have great prospecting potential and are worth further work.The above analysis results can provide certain reference for studying the metallogenic of Laojunshan rock mass and molybdenum deposit.
