摘要
凤凰山Ag－Pb-Zn多金属矿床产在寒武系类复理石建造中，赋矿围岩为砂岩和页岩，矿体受北西西向的构造破碎带控制。含矿热液流体沿构造破碎带充填，形成规模较大的多金属矿床，矿床的形成具有多期多阶段的特征。银主要以银的独立矿物形式存在，和方铝矿、硫锰矿、闪锌矿、菱锰矿及黄铁矿的关系较为密切。主要的银矿物有辉锑铅银矿、深红银矿、杂辉锑银铅矿、捷辉锑银铅矿、柱硫锑铅银矿、脆银矿、辉锑银矿和银黝铜矿等。银矿物主要形成于石英-硫化物阶段和石英-碳酸盐、硫盐阶段。
The Fenghuangshan silver-lead-zinc polymetallic deposit occurs in the Cambrian fly-schoid sandstones and shales, controlled by NWW-trending structural shatter zones. Ore-bearinghydrothermal solutions filled aIong the structural zones, forming large-scale polymetallic orebod-ies. The ore-forming process shows multiphase and polystage features. Silver mainly occurs as sil-ver minerals, associated closely with galena, alabandite, sphalerite and rhodochrosite. The majorsilver minerals include diaphorite, pyrargyrite, fizelyite, teremkovite, freieslebenite, stephanite,miargyrite and freibergite. Silver minerals were mainly formed during the quartz-sulfide stage andthe quartz-carbonate, sulfosalt stage.
