Origin of magnesium and potassium ions in Lake Vanda, Antarctica


THE Dry Valley area of southern Victoria Land is one of the greatest ice-free areas, in Antarctica and contains lakes and soils which are noted for their saline character. Particular attention has been focused on the origin of these salts, first because it contributes to an understanding of Antarctic weathering and soil formation, second because it is related closely to the glacial history of the Dry Valley area, and third because it is connected with marine invasion and the Pecten gravels1 in Wright Valley.
