摘　　要：滇东北铅锌(银)矿集区,是云南省重要的铅锌(银)产地,含6个矿带,总计上表(截止2008年底)Pb+Zn 766.9 180万t(Pb 291.0723万t、Zn 475.8475万t),占全省上表Pb+Zn储量的19.36%。其主体地质特征与MVT型相似,但也存在差异,可称为MVT型含氟、钡的新亚类———滇东北型。The Pb-Zn(Ag)deposit concentration area in NE Yunnan is the important Pb-Zn(Ag)production area of Yunnan,including 6 metallogenetic zones and the Pb+Zn sum total 7669.180 thousand t(Pb 2910.732;Zn 4758.475)in BS(by the End of 2008),which accounts for 19.36% of whole Pb+ZN reserves in BS of Yunnan.The main geological characteristics of them are similar to those of MVT type,with a little differences,which can be called the F-bearing,Ba-bearing new sub-type—NE Yunnan type of MVT type.
