摘　　要：质疑了张志斌等(2010)一文关于东升庙—三贵口锌多金属硫铁矿矿床锌矿体和硫矿体的分类及其各类矿体形态、矿石结构构造和稀土配分模式等方面的依据以及一些论证过程,否定了其在此基础上提出的锌矿体为沉积形成矿源层,后期改造成矿的观点和其得出的下一步找矿方向。锌矿体主要有9号、2号、11号等6个矿体,硫矿体主要有1号、3号、4号等4个矿体。呈层状整合分布于石墨片岩中且和后者具有一致的稀土配分模式的9号和其他矿体一样都是沉积喷流过程的产物,其矿石结构也支持这一点。在东升庙—三贵口地区下一步的找矿方向应该是寻找下部的根部矿体。Such the ideas on genesis and ore prospecting of the Dongshengmiao deposit proposed by Zhang et al.（2010） are questioned in this paper as the classification of orebodies（i.e.,sulfur orebodies and zinc orebodies）,shapes,structure and texture,REE pattern of both sulfur and zinc ore.It was negated in this paper that,in Dongshengmiao deposit,sulfur orebodies were resulted from SEDEX process and zinc orebodies were caused by hydrothermal reworking after sulfur orebodies forming,and the further exploration be here.In Dongshengmiao-Sanguikou area,there are mainly six zinc orebodies（i.e.,orebodies 9,2,11,3,10 and 4） and four sulfur ones（i.e.,orebodies 1,3,4,and 2）.Orebody 9,occurring comfortably in schist and having the same REE pattern model with the wall rock,should be resulted from the SEDEX mineralization process,similar to the mineralization of other orebodies.It is proposed that further ore exploration should be concentrated upon the deeper boot orebody of SEDEX deposit.
