The Eastern Branch of the East African Rift System diverges from a single, c. 50 km wide rift in southern Kenya to a c. 200 km wide zone in northern Tanzania, where it is comprised of three distinct rifts with different orientations. The western part of this zone contains two rift branches: the Natron-Man yara-Balangida and Eyasi-Wembere rifts. Each rift contains individual basins that are defined here on the basis of structural and geophysical interpretations. These basins are shallow (<3km…

Precambrian lithospheric controls on the development of the East African rift system
We propose a new kinematic framework for the East African rift system linking the development of the Eastern and Western rifts via stress transmission across the Archean Tanzania craton. The proposal
Lithospheric Controls on the Rifting of the Tanzanian Craton at the Eyasi Basin, Eastern Branch of the East African Rift System
Continental rifts most often nucleate within orogenic belts. However, some studies in the East African rift system have shown that continental rifts can also develop within cratons. This work
1 The East African Rift System : Tectonics , climate and biodiversity
The East African Rift System (EARS) is one of the most prominent rift systems on Earth and transects the high-elevation East African Plateau. The EARS is famous for its tectonics and geology and has
Lithospheric low-velocity zones associated with a magmatic segment of the Tanzanian Rift, East Africa
Rifting in a cratonic lithosphere is strongly controlled by several interacting processes including crust/mantle rheology, magmatism, inherited structure and stress regime. In order to better
The offshore East African Rift System: Structural framework at the toe of a juvenile rift
The Cenozoic East African Rift System (EARS) extends from the Red Sea to Mozambique. Here we use seismic reflection and bathymetric data to investigate the tectonic evolution of the offshore branch
Neogene-Holocene rift propagation in central Tanzania: Morphostructural and aeromagnetic evidence from the Kilombero area
Based on field studies supplemented by remote sensing and aeromagnetic data from central Tanzania, a Phanerozoic structural history for the region can be developed and placed in a broader rift
A 300 Million Years History of Rift Lakes in Central and East Africa: An Updated Broad Review
Over the past 300 Ma, the complex geological history of the African continental plate has been marked by an important development of lacustrine domains of various size. We present in this paper an


Age of Fault Movements in Tanzanian Sector of East African Rift System
THE Neogene volcanic province of northern Tanzania is a southerly extension of the more extensive volcanic areas of Ethiopia and Kenya. It stands astride the Eastern Rift Valley and represents a
Lithospheric thinning associated with rifting in East Africa
A fundamental mechanism of some continental rifting processes appears to be the transmission of thermal energy into the lithosphere by asthenospheric upwelling (the ‘active’ mechanism of Sengör and
Variations in the along‐axis segmentation of the Afar Rift system
Both oceanic and continental rifts show regular along-axis segmentation, but the relationship, if any, between the two is poorly understood. The tectonically active East African Rift system
Crustal heterogeneity and basement influence on the development of the Kenya Rift, East Africa
Structural and metamorphic studies within the exposed Precambrian basement in Kenya indicate that a number of heterogeneities exist within the lithosphere beneath the line of the Kenya Rift. Of
Along-axis segmentation and isostasy in the Western rift, East
Structural variations along the southern sectors of the Western rift, East Africa, have previously been described, but subsurface structures in the northern sector (Uganda, Zaire) are virtually
Seismic images illustrate the deep roots of the Chyulu Hills Volcanic Area, Kenya
A recent delay time tomography experiment has revealed the still ongoing processes that formed the East African Rift, the world's largest continental rift system. These new data have been used to
The Somalia plate and the East African Rift System: present-day kinematics
SUMMARY The motion of the Somalia plate relative to the Nubia (Africa), Arabia and Antarctica platcs is re-evaluated using a new inversion method based on a Monte Carlo technique and a least absolute
