Abstract

The diatom stratigraphy of a 23-m sediment core from Lake Tilo, a maar lake in the Ethiopan Rift Valley, provides a 10,000-yr record of lake salinity and trophic status. The results show that the lake remained relatively fresh throughout the early Holocene arid intervals, due to high rates of geothermal groundwater discharge. Palaeoclimatic interpretation of palaeosalinity proxies from the sediments of volcanic crater lakes should be approached with caution
