Abstract

Intense sublacustrine hydrothermal activity has been investigated by scuba diving during the TANGANYDRO project along the Zaire side of the north Tanganyika trough (East African Rift). At the Pemba site, the vents are characterized by fluids with a temperature between 53 and 88-degrees-C, associated with iron sulfide veins. At Cape Banza site, the activity is characterized by aragonite chimneys and fluids with a temperature varying between 66 and 103-degrees-C. These hydrothermal vents are located at the intersection of N135 or N180 Precambrian cleavage, and N45 to N90 transverse fractures recently reactivated.
