摘要
湘黔川鄂边境早震旦世的锰矿称为民乐式锰矿。锰矿床(点)的分布大部分受扬子准地台东南边缘之武陵台陷的控制,锰矿主要生成于滨海相的半局限海湾含锰页岩亚相中,应属于暖温带—亚热带气侯,化石藻类发育的地段,菱锰矿颗粒密集,锰品位增高。分析此类矿床的成矿物质来源、锰质搬运方式、锰质沉积作用,探讨此类矿床成因及成矿模式,对缺锰地区寻找类似锰矿床具有重要意义。
Hunan,Guizhou,Sichuan,Hubei and the border is called the Early Sinian in folk style of manganese ore.Manganese ore deposits(spots)are along the distribution of most of southeastern edge of the quasi-Wuling platform of Yangtze.Manganese generated in the Gulf littoral of manganese shale of semi-confined sub-phase belongs to warm temperate-subtropical climate,and lots of fossil algae growth,rhodochrosite particles intensive,and higher grade is manganese resource.Analysis of minerals is requined into the source of manganese removal methods,manganese deposition,the causes of such deposits and metallogenic model,similar to Mn deficiency manganese deposit areas in search of great significance.
