本文分析了南极洲富士冰穹冰芯3个500 mm剖面的离子化学组分剖面，并与表层雪中的离子化学组分剖面进行了比较。3.0和8.9 kyr的部分来自全新世，13.3 kyr的部分略早于全新世。在每个切片内的2 mm厚切片上进行分析。在每一深度，主要的离子种类是Na+，H+，Cl-和SO 42 A。SO 42，Na+和Mg 2+的水平随深度的变化，在每个部分从几毫米到几厘米的距离。此外，Na+和SO 4之间的相关系数和Mg 2+和SO 4 2之间的每个深度为0.90或更大，在地面雪（定义为0-3.4米从表面）的值为0.59或更小的对比。这些结果表明，几乎所有的Na+和Mg 2+在全新世冰中存在的Na 2SO 4和MgSO 4盐，这些盐的形成不仅发生在大气中的传输过程中，而且在积雪层。
Abstract We analyzed the profiles of ionic chemical species in three 500 mm sections of an ice core from Dome Fuji, Antarctica, dated 3.0, 8.9 and 13.3 kyr BP (before present), and compared the profiles to those in the surface snow. The 3.0 and 8.9 kyr sections are from the Holocene and the 13.3 kyr section slightly predates the Holocene. The analyses were done on 2 mm thick slices within each section. At each depth, the primary ionic species were Na+, H+, Cl– and SO4 2 A The SO4 2, Na+ and Mg2+ levels varied with depth in each section over distances ranging from several millimeters to several centimeters. Also, the correlation coefficients between Na+ and SO4 and between Mg2+ and SO4 2 for each depth were 0.90 or greater, in contrast to the value of 0.59 or less in the surface snow (defined here as 0–3.4 m from the surface). These results suggest that almost all Na+ and Mg2+ in the Holocene ice exists as Na2SO4 and MgSO4 salts, and the formation of these salts occurs not only in the atmosphere during transport, but also in the firn layer.
