The Cho Don (including the Na Bop, Na Tum, Pu Sap, Ba Bo and Lung Vang deposits) and Cho Dien (including the Phia Khao, Lung Hoai, La Poanh, Bo Pen, Binh Chai, Deo An, Bo Luong deposits) mining areas are characterized by the large reserve and high grade of Pb-Zn ore and indium in Cho Dien district, Bac Kan Province, northeast Vietnam (Fig. 1). Total ore reserves in these mining areas reach up to 20.1 Mt of ores, in which there are 0.99 Mt of metals (Pb+Zn) (Dovzhikov et al., 1965; Tran et al., 2012, Nguyen et al., 2000). Some earlier studies classified ore deposits in the Cho Don and Cho Dien mining areas into Mississippi Valley type deposits (MVTs). Some of the later studies assign them to Pb-Zn hydrothermal deposits classified into magmatic hydrothermal system based on the mineral assemblage and trace elements characteristics. The aim of this study is to clarify the type of the Na Bop deposit in the Cho Don mining area and the Lung Hoai deposit in the Cho Dien mining area based on the characteristics of mineralogy, geochemistry and formation environment.
