摘　　要：拉巴铁多金属矿位于滇西北格咱成矿带。喜马拉雅期安山岩以岩株、岩脉侵入中三叠统北衙组碳酸盐中,矿化及矿体受东、西两侧外缘接触带矽卡岩控制,赋存于构造和岩性有利部位的矽卡岩中。应属热液型矽卡岩铁多金属矿,以磁铁矿为主,伴有铜、金、银、钨、钼。The Laba Fe multimetallic deposit is in the Geza metallogenetie zone in NW Yunnan. The Himalay- an andesite stock and vein intrude into the carbonate rock of Middle Triassic Beiya Formation. And the metallogene- sis and ore body are controlled by the skarn in E, W both sides of outer contact, in the skarn of advantageous part of structure and lithologic character. It must be a skarn Fe multimetallic deposit of hydrothermal type, with the ma- jor ore magnetite and the associated elements Cu, Au, Ag, W and Mo, etc.
