| 摘 要： | 河北丰宁银多金属矿床赋存于隐爆角砾岩体中,发育一组典型低温热液矿物组合的围岩蚀变,矿化为典型低温热液成因的黄铁矿-闪锌矿-方铅矿-黄铜矿硫化物组合;控矿隐爆角砾岩划分为震裂花岗岩相、震碎花岗岩相、熔浆角砾岩相和气爆角砾岩相4类;宏观、微观研究认为其中的硅质角砾由4次喷发作用形成;气爆形成的萤石化可确定赋矿空间的分布规律.

| Abstract: | The Fengning silver-polymetal deposit occurs in cryptoexplosive breccia body with a set of epithermal minerals in altered host rock.Mineralization exhibits epithermal sulfide assemblage of pyrite-sphalerite-galenite-chalcopyrite.The cryptoexplosive breccia could be devided into cracking granite,broken granite,magmatic melt and gas explosive facies.The macro-and micro researches demostrate that four eruptions lead to the silicon talus debris in the crytoexplosive breccia.The gas explosive fluoritization can determinate the spatial regulaion of ore-body occurrence. |

| Keywords: | cryptoexplosive breccia facies silicon talus debris Fengning silver-polymetal deposit Hebei province |
