Na2SO4 and MgSO4 salts during the Holocene period derived by high-resolution depth analysis of a Dome Fuji ice core
We analyzed the profiles of ionic chemical species in three 500mm 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 s...

We analyzed the profiles of ionic chemical species in three 500mm 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 2mm thick slices within each section. At each depth, the primary ionic species were Na+, H+, Cl- and SO4^[2-]. The SO4^[2-], Na+ and Mg2+ levels varied with depth in each section over distances ranging from several millimeters to several centimeters.
