摘　　要：通过大量的钻探、坑(井)探及物化探工作,在河北省涞水县境内的燕山斑岩型铜(钼)矿成矿带内的燕山台褶带燕山期安妥岭花岗闪长斑岩岩体的内、外接触带及太古宇阜平岩群角闪斜长片麻岩中发现了安妥岭钼矿床。钼矿体厚大,ZK2孔见矿30层,最厚13 m,总见矿厚度108 m。ZK3孔见矿10层,厚度55 m,主矿体厚37 m。钼矿化与围岩硅化、钾化的蚀变发育程度密切相关。目前识别出的矿石类型主要有花岗闪长斑岩型、硅化角闪斜长片麻岩型和青盘岩化蚀变岩型,矿化蚀变具斑岩型矿床特征。该矿属于斑岩型中-低温热液矿床。Through much exploration work of drilling, pitting and geophysics and geochemistry in the Yanshanian porphyry copper （molybdenum） metallogenic belt of Laishui Conty, Hebei deposits was found in the internal and external contact zone of Yanshan Province, Antuoling molybdenum ore granodioritic porphyry and hornblende plagioclass gneiss of Archean Fuping Group. Molybdenum ore bodies are thick. More than 30 layers have been seen in borehole ZK2 with the thickest of 13 m and the total thickness of 108 m. 10 layers with the thickness of 55 m have been seen in borehole ZK3, the thickness of the main ore body is 37 m. Molybdenum mineralization is related with the development degree of wall rock＇s silicification and potassic alteration. The type of ore are granodiorite, silicified hornblende plagioclass gneiss and propylite altered rocks. The alteration of mineralization has characteristic of porphyry-type deposit. This deposit is medium-low temperature hydrothermal deposit.
