Summary:The main field results of investigations into sublacustrine hydrothermal seeps at Pemba and Cape Banza, and two newly discoverd sites at Luhanga and Mbemvi, are presented. The sites are located along the major N-S border faults of N Tanganyika, the Uvira, and the W and E Ubwari border faults. Thermal fluid circulation is permitted by crack openings following cleavage and fractures within the Precambrian basement, which seem to be related to N 130 degrees normal-dextral faults which locally intersect the N-S major trend. Analyses of hydrothermal fluids and sulphide mineralizations from sites in the area, as well as the identification of fault mechanisms, are presently in progress. They will allow both the origin and the pathways for hydrothermal fluids to be determined and permit the influence of such hydrothermal emissions on the lake water chemistry and hypolimnion structure to be determined.
