Tectonic, climatic and hydrothermal control on sedimentation and water chemistry of northern Lake Malawi (Nyasa), Tanzania

Physico-chemistry and isotopic data of epi- and metalimnetic waters document the importance of the various water sources but also of evaporation and mixing processes linked to the thermo-haline stratification. Even if hydrothernal discharges have not been observed in the lake, they contribute to the lake chemistry at least through riverine inputs (Kiwira River).
