We discuss detrital particles in the modern samples and their relation to source areas and sedimentation dynamics authigenic minerals in relation to physico-chemical conditions of the modern basin and grain size distribution in relation to sedimentation agents, climate and sedimentary environments. Our results are based in part on field observations and in part on laboratory analysis executed at Laboratoire de Géologie du Quaternaire, Luminy in Marseille. Similar to other closed basins (see also Eugster and Kelts, 1983 Yuretich, 1979, 1982), a good understanding of sedimentation in the modern environment where the complex physico-chemical components can be observed and studied directly, is of great importance to the interpretation of the ancient lake's environmental dynamics. Map of Lake Magadi, Kenya indicating the South East Lagoon. The basic goal of this type of studies is to establish a relationship between sedimentation dynamics and physico-chemical nature of the modern environment. alcalicus from lake Natron, and DNA fingerprint similarity indices were. In this paper, we report of results from analytical studies carried out on modern sediments from Lake Natron in Tanzania.
