摘要
滇西北衙金多金属矿田是金沙江-红河富碱斑岩成矿带的重要组成部分,矿田内成矿元素以金、铁、铜为主,伴生大量的铅、锌、银等。该矿田内生矿化以斑岩体为中心,向外环状依次分布斑岩型、矽卡岩型及热液型三种不同类型的矿化,三类矿化成矿时代集中出现于37~32Ma之间。三种类型的矿化属同一岩浆热液成矿系列中不同矿化阶段的产物。
Beiya multimetallic orefield in NW Yunnan is an important member of Jinshajiang-Honghe alkali-rich porphyry metallogenesis zone.The main metallogenesis elements in orefield are Au,Fe and Cu,with a large amount of associate Pb,Zn and Ag,etc.There are 3 different types of metallogenesis from the endogenetic metallogenesis porphyry body centre of this orefield are successively outwards porphyry,skarn and hydrothermal type metallogenesis.The ages of them are between 37-32Ma,which belong to the different stage of a same magmatic hydrothermal metallogenesis series.
