Abstract: Xionger Mountain area is an important gold, silver, lead, zinc and molybdenum polymetallic mineral deposit area in Henan Province.121 deposits have been identified.It is found that the formation of polymetallic minerals in this area is closely related to the intrusion of Mesozoic intermediate-acid magma.There are concealed rock bodies in the deep part of the area where the existing ore deposits are concentrated.Based on the analysis of the characteristics of gravity and magnetic fields in Xionger mountain area, the intrusion model of concealed rock mass in Xionger Mountain area is established.There are mainly Zhaiwa concealed rock mass in Xionger Mountain Western section, with an area of about 310 km² and three stepped depths:0~0.8 km, 0.8~2 km, 2~4 km; Tieluping-Huashan concealed rock mass in the middle part of Xionger Mountain is located between Zhaiwa concealed rock mass and Huashan rock mass, with an area of 184 km² and a depth of 3~5 km; The Jiuxian-Huashan concealed rock mass in the east part of Xionger Mountain has an area of 338 km², a depth of 0~1.5 km in the north, and gradually deepening to 1.5~3 km in the south.According to the distribution and zoning characteristics of regional minerals and the intrusion model of concealed rock mass, the deep metallogenic model is predicted.Research shows:there is potential to search for large porphyry molybdenum tungsten copper deposits and large gold deposits in the western Xionger Mountain; The concealed rock mass in the middle section is deep and Mainly searches for low-and medium-temperature minerals; The geological exploration in the eastern section is relatively high, and porphyry-type molybdenum-gold-copper deposits still have potential in the deep part of the deposit.
