Abstract

Chemical studies indicate that during the first half of the history of Lake Zeribar, since about 14,800 years ago, the outlet ran very intermittently, thus resulting in a carbonate deposition and a moderate chloride content of the water. The later sediments are largely littoral and cannot easily be interpreted. A fall in exchangeable potassium at the top is probably correlated with the development of extensive beds of aquatic macrophytes. The data appear to be in harmony with those derived from pollen analysis.
