Extractable Fe

Soils from various drained thaw lake basins near Barrow, AK were extracted with various solvents reflecting different Fe (iron) pools. Values are presented in micromoles per g and micromoles per cm^3 (the latter being more appropriate for comparing light organic and dense mineral layers). See Lipson et al. (2013) Global Biogeochemical Cycles 27:1-11, doi:10.1002/gbc.20038, and Lipson et al. (2010) J Geophys Res-Biogeosci (G) 115, G00I06, doi:10.1029/2009JG001147. The mineral types generally associated with each solvent are indicated.

采自美国阿拉斯加州巴罗周边各类疏干融湖盆地的土壤样本，采用多种溶剂进行萃取，以表征不同形态的铁库。数据以微摩尔每克及微摩尔每立方厘米为单位给出，后者更适用于对比轻质有机层与致密矿质层的相关数据。相关研究细节参见Lipson等人2013年发表于《全球生物地球化学循环》（Global Biogeochemical Cycles）第27卷第1-11页的论文，DOI：10.1002/gbc.20038；以及Lipson等人2010年发表于《地球物理学研究杂志：生物地球科学》（原缩写J Geophys Res-Biogeosci (G)）第115卷G00I06号的论文，DOI：10.1029/2009JG001147。每种溶剂所对应的典型矿物类型均已标注。
