摘　　要：朱家庄锰银矿床位于河北省涞源县朱家庄一带,大地构造位置上位于华北克拉通北缘,燕辽-太行山裂陷槽的西部边缘,沉积有巨厚的中元古界长城系高于庄组白云岩。高于庄组为主要含锰层位,为该区锰银矿的形成提供了成矿物质来源。燕山期构造-岩浆岩发育,构造呈近东西向、北西向,岩浆岩主要为花岗斑岩,岩浆上升侵位过程中,活化萃取长城系高于庄组含锰灰岩,使其沿着有利的构造部位迁移、富集,在不同的构造空间沉淀成矿。因此,朱家庄锰银矿床成因类型为次火山热液型。The Zhujiazhuang manganese silver deposit is located in the Zhujiazhuang area of Laiyuan County,Hebei Province.It is structurally located on the northern edge of the North China Craton and the western edge of the Yanliao-T'ai-hang Mountain rift.It is deposited with thick middle Proterozoic Changcheng System Gaogaozhuang formation dolomite.The Gaogaozhuang formation is the main manganese bearing layer,it provide a source of ore-forming materials for the formation of manganese silver deposits in this area.During the Yanshan period,the tectonic magmatic rocks developed in a nearly east-west and northwest direction.The magmatic rocks were mainly granite porphyry.During the process of magma upwelling and emplacement,the manganese bearing limestone of the Gaoyuzhuang Formation of the Changcheng System was activated and extracted,causing it to migrate and enrich along favorable structural positions,and precipitate and form mineralization in different structural spaces.Therefore,the genetic type of the Zhujiazhuang manganese silver deposit is a sub volcanic hydrothermal type.
