Chemical composition of iron-manganese ores from Swedish lakes

The chemical composition of iron-manganese were analysed for three sediment cores from Swedish lakes. From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals...针对瑞典湖泊的3根沉积物岩芯，分析了其铁-锰化学成分。1983年至1989年，美国国家海洋和大气管理局国家环境信息中心（NOAA-NCEI）编制了NOAA-MMS海洋矿物相关内容。
