摘　　要：阿尔金碳酸盐岩系具有较好的锰矿成矿条件,青砂沟大型锰矿的发现,为我们提供了该地区锰矿找矿的方向。该地区含锰岩系的Fe/Mn比值、V/(V+Ni)比值显示,含锰物质是在氧化-次氧化环境沉积富集的;Al/(Al+Fe+Mn)比值显示,具有热水沉积的特征;SiO_(2)/Al_(2)O_(3)比值显示,其物源可能来自洋壳深部。在此基础上建立矿床成矿模型,总结找矿方向。The Altun carbonate rock system has good manganese ore mineralization conditions.The discovery of Qingshagou large manganese deposit provides us with the direction of manganese ore prospecting in this area.The ratios of Fe/Mn and V/(V+Ni)of the manganese-bearing rock series in this area indicate that the manganese-bearing materials were deposited and enriched in oxidization-sub-oxidation environment.The Al/(Al+Fe+Mn)ratio shows that it is characterized by hydrothermal deposition.The SiO_(2)/Al_(2)O_(3) ratio indicates that the provenance may come from the deep ocean crust.On this basis,the ore-forming model of the deposit is established,and the prospecting direction is summarized.
