摘　　要：麦兹晚古生代火山盆地位于西伯利亚板块阿尔泰陆缘活动带东段,盆地中赋存有丰富的铅锌、铜铁等多金属矿产,其中可可塔勒大型铅锌矿、蒙库大型铁矿床、阿克哈仁铅锌矿、大桥铅锌矿等具有代表性,各类矿床表现出海底火山喷气沉积成矿的特征。麦兹盆地多金属矿床具有明显的规律性,铁矿主要分布于盆地北侧下泥盆统康布铁堡组下亚组,铅锌矿主要分布于盆地南侧下泥盆统康布铁堡组上亚组。今后应注意在蒙库铁矿区及外围寻找铜矿,在盆地中部的阿尔泰镇组沉积岩区寻找红墩式(沉积)铅锌矿,同时加强可可塔勒铅锌矿带西段和深部的勘查工作。The Maizi Paleozoic volcanic-sedimentary basin is located in eastern mobile belt of Altay continental margin of Siberian plate. A large number of lead, zinc, and iron deposits, such as Keketale, Mengku, Akeharen and Daqiao deposit, were formed in the Maizi basin. These deposits are characterized by volcano-sedimentary exhalation mineralization. The iron and lead-zinc deposits occur mainly in north- ern and southern part of the Maizi basin, respectively. The paper presents further exploring directions for metal deposits： copper ore in the Mengku iron district and its surroundings, Sedex-type lead-zinc deposits in sedimentary rocks of Altay Town Formation, and more exploration should be done in the west section and depth of the Keketale lead-zinc ore belt.
