A View on the Formation of Saline Waters in the Dry Valleys
The previous report by TORII et al. (Nankyoku Shiryo, 58,116,1977) on the salt balance in the Don Juan basin pointed out the presence of calcium in excess when the total salt deposits in the basin are assumed to have resulted simply from the evaporation of sea water.

| Summary: | The previous report by TORII et al. (Nankyoku Shiryo, 58,116,1977) on the salt balance in the Don Juan basin pointed out the presence of calcium in excess when the total salt deposits in the basin are assumed to have resulted simply from the evaporation of sea water. Concerning the evolutionary processes of saline waters in the Dry Valleys, sources of the salts other than trapped sea water were not necessarily excluded, and sea spray, ion exchange and rock weathering theories have been suggested by many investigators. This paper presents the results obtained by further examination of the processes of saline water formation, on the basis of the analytical results of the DVDP cores from the Wright Valley, the information on the chemical characteristics of the water systems in the Dry Valleys, and a recent reconnaissance in the Labyrinth and the Pearse Valley. It is more likely that the chemical composition of waters in these saline lakes is mainly due to the atmospheric salt rather than the modification of trapped sea salt. |
