| 摘 要： | 新疆玛尔坎苏一带锰矿赋存于上石炭统喀拉阿特河组地层中，锰矿层呈层状、似层状产出，顶底板均为泥灰岩、泥晶灰岩。矿层产状与地层产状一致，明显受层位控制，延伸较为稳定。锰矿品位比较高，局部富集品位高达50%以上，通过X衍射、电子探针等实验方法对锰矿石矿物成分分析，推测矿床为海相沉积成因，且经后期热液多次改造用作影响。

| Abstract: | The manganese deposits in the Maerkansu region, Akto county, Xinjiang are hosted in the Upper Carboniferous Galaatehe Formation. Their occurrence is featured by layered and quasi-stratified forms with top and bottom layers all of marls and mudstones. The occurrence of seams is consistent with the strata, obviously controlled by horizons with relatively stable extension. The manganese ore grade is relatively high, locally the enrichment grade is as high as more than 50%. Through the analysis of the mineral composition of manganese ore by X-ray diffraction, electron probe and other experimental methods, it is inferred that the ore deposit formed in marine sediments, and has experienced many times of reformation by the later hydrothermal fluids. |
