摘　　要：盘龙山银多金属矿赋存于隐爆角砾岩体内,矿体平面上总体呈北西走向,为形状不规则的纺锤形、椭圆形,剖面上矿体呈柱状、筒状。金属矿物主要有黄铁矿、赤铁矿+褐铁矿、银金矿、碲银矿、硫碲银矿、方铅矿+白铅矿,成矿元素为Ag,共伴生元素为Au、Pb,矿石中还含有Cu、Zn、Mo等元素。在角砾岩体旁侧有小型正长岩体的存在,在角砾岩体西北部有构造带,燕山期构造岩浆活动为成矿提供了富含活化剂的热液及热运力条件,结合本区地质条件及矿物组成,认为本区银多金属矿床成因类型属中低温热液角砾岩型矿床,J_(I)角砾岩体的深边部是扩大矿体规模的有利地段。Panlongshan silver polymetallic deposit occurs in cryptoexplosive Breccia Body.The ore body is generally nw-trending in plane,with irregular shape of spindle and ellipse,and columnar and cylindrical in section.The main metallic minerals are pyrite,hematite+limonite,silver-gold,tellurite,silver-tellurite,GALENA+white lead.The ore-forming elements are Ag and associated elements are Au and Pb.The ore also contains Cu,Zn and Mo.There is a small syenite body beside the BRECCIA body and a tectonic belt in the northwest of the Breccia body.The tectono-magmatic activity of the Yan Mountains period provided the conditions of hydrothermal and thermal transportation rich in activators for the mineralization,according to the geological conditions and mineral composition,the silver-polymetallic deposit belongs to mesothermal-epithermal Breccia type.The deep edge of J_(I) BRECCIA body is favorable for enlarging the scale of ore body.
