摘　　要：福建省平和县壶嗣矿区为银铅锌多金属的矿,控矿岩体为燕山早期的花岗岩,岩体与围岩(流纹质晶屑凝灰熔岩)进行了强烈的热液蚀变作用,形成了不规则椭圆形的隐爆角砾岩筒和带孔裂隙的发育,使含矿热液充填于隐爆角砾岩的裂隙中,形成银铅锌多金属矿富集的场所。本文从区域成矿地质背景、矿体地质特征等方面介绍了该矿的形成,并对矿体成因、隐爆角砾岩体(筒)的形成及找矿标志进行了分析。Husi mining area,Pinghe County,Fujian Province is a Ag-Pb-Zn polymetallic deposit,and the ore-controlling rock mass is granite in early Yanshan period.The rock mass and surrounding rock(rhyolitic crystal debris tuff lava)have undergone strong hydrothermal alteration,forming irregular oval cryptoexplosive breccia tube and perforated fractures,which make ore-bearing hydrothermal solution fill in the fractures of cryptoexplosive breccia,forming a place where Ag-Pb-Zn polymetallic deposits are enriched.This paper introduces the formation of this mine from the aspects of regional metallogenic geological background,geological characteristics of ore bodies,etc.,and analyzes the genesis of ore bodies,the formation of cryptoexplosive breccia bodies(tubes)and prospecting criteria.
