摘　　要：安妥岭矿区位于河北省涞水县北部,地处华北地台北缘、燕辽钼(铜)成矿带西南端。该成矿带受区域NNE向上黄旗—乌龙沟深大断裂和紫荆关—灵山断裂的联合控制。在总结区域地质背景、矿区地质特征的基础上,分析区内岩石地球化学特征、构造特征、岩体侵入位置与矿体分布之间的关系,初步探讨安妥岭钼矿床的控矿因素和矿床成因,认为安妥岭钼矿床属于中—低温热液型矿床。提出NNW、NW向断裂活动促进矿体的进一步富集,在岩体西部存在着大量与成矿有关的断裂,是下一步找矿重点;矿区东部岩体与地层接触部位的隐爆角砾岩也是矿体富集的有利部位。本研究为矿区深部及外围探矿提供了新的找矿方向。Antuoling mining area is located in the northern of Laishui County,Hebei Province,which is located in the north of North China Platform and southwest end of Yan-Liao molybdenum（copper）metallogenic belt.The metallogenic belt is controlled by regional NNE upward Huangqi-Wulonggou deep fault and Zijingguan-Lingshan fault.Based on the summary of regional geological background and geological characteristics of mining area,this paper analyzes the relationship among rock geochemical characteristics,structural features,rock mass intrusion location and ore body distribution.The ore-controlling factors and genesis of Antuoling molybdenum deposit are preliminarily discussed,and it is believed that Antuoling molybdenum deposit belongs to the medium-low temperature hydrothermal deposit,and proposed that NNW,NW tectonic activity promote the further enrichment of orebody.There are a large number of ore-related fault structures in the west of rock mass,which is the next step of prospecting.The crypoexplosive breccia occurred in the contact area between rock mass and stratum in the eastern of mining area is also a favorable part for orebody enrichment.This research provides a new prospecting direction for deep and peripheral prospecting in mining area.
