(Table 2) Geochemistry of biotite and ilmenite at DSDP Sample 66-493-59-1A

Total iron expressed as FeO for biotites and distributed between Fe2O3 and FeO following Carmichael's (1967) method for ilmenites. Empty cells mean no data.

本数据集针对黑云母样品，其总铁含量以氧化亚铁（FeO）形式表示；并按照Carmichael（1967）提出的钛铁矿分析方法，将总铁分配至三氧化二铁（Fe₂O₃）与氧化亚铁（FeO）两种价态的铁组分中。空白单元格代表无数据。
