摘　　要：河北省涞源县木吉村铜(钼)矿床目前已探明为一大型斑岩型铜(钼)-矽卡岩型铁铜-热液脉型铅锌银"三位一体"多金属矿床。作者结合最新勘查成果,对该矿床的成矿地质背景、矿床地质特征进行了总结,探讨了该矿床的成因和成矿模式。研究表明,木吉村铜(钼)矿床位于山西断窿与燕山台褶带的过渡地带,乌龙沟-上黄旗深断裂带中。该矿床的主要控矿构造为F4断裂,成矿母岩闪长玢岩与古火山构造关系密切。该矿床具有典型的面型蚀变分带及矿化分带。其矿床成因主要为斑岩-矽卡岩型高(中)温热液矿床,以"多位一体"和多阶段成矿为特点。The Mujicun copper（molybdenum） deposit in Laiyuan County of Hebei Province is a proved large-size porphyry copper（molybdenum）-skarn iron copper-hydrothermal lead-zinc-silver polymetallic deposit.In combination with the latest survey results of its metallogenic geological background,the authors studied the genesis and metallogenic model of this ore deposit.It is shown that the Mujicun copper（molybdenum） deposit is located in the transitional zone between the Shanxi faulted dome and the Yanshan platform fold belt,within the Wulonggou-Shanghuangqi deep fault.The main ore-controlling structure is F4,and the parent rock diorite porphyrite is closely related to the paleo-volcanic structure.The ore deposit has typical planar alteration zoning and mineralization zoning,and is genetically of porphyry-skarn high（medium）-temperature hydrothermal fluid type,characterized by ＂multi-type integration＂ and multi-stage mineralization.
