ALKALI METAL CONSTRAINTS ON THE ORIGIN OF SALTS IN LAKES AND PONDS FROM THE McMURDO DRY VALLEYS, ANTARCTICA
Alkali metals in lake, pond, and ice samples of the McMurdo Dry Valleys in southern Victoria Land, Antarctica were studied to clarify the origins of dissolved salts and to estimate their evolutional history. The contents of Li, Rb and Cs largely varied ranging from 0.30ppb to 390ppm, 0.06ppb to 514p...
