Contribution of transverse structures, magma, and crustal fluids to continental rift evolution: the East African rift in southern Kenya
Kattenhorn, S A; Muirhead, J; Dindi, E; Fischer, T P; Lee, H (2013-12-13)The Magadi rift in southern Kenya formed at ~7 Ma within Proterozoic rocks of the Mozambique orogenic belt, parallel to its contact with the Archean Tanzania craton. The rift is bounded to the west by the ~1600-m-high ... -
Fault-controlled fluid migration during early-stage continental rifting in the Magadi Basin, Kenya
Muirhead, J; Lee, H; Fischer, T; Kattenhorn, SA; Ebinger, C; Kianji, G; Maqway, M; Thomas, N; Onguso, B. (University of Nairobi, 2014)The mechanisms controlling the migration of mantle-derived, CO2-rich fluids in early-stage continental rifts are poorly constrained, yet have important implications for processes occurring during the initiation of continental ... -
Fault-related Soil Efflux of Mantle-derived CO2 in the Magadi and Natron Basins, East African Rift
Lee, H; Muirhead, J; Fischer, T P; Kattenhorn, SA; Ebinger, C J; Thomas, N.; Kianji, G; Onguso, B; Maqway, MD (University of Nairobi, 2014)The Magadi (Kenya) and Natron (Tanzania) basins of the East African Rift are in an early stage (< 7 Ma) of continental rifting. The many normal faults observed in these areas create sediment-filled basins and a large number ... -
Gas geochemistry of volcanic and geothermal areas in the Kenya Rift: implications for the role of fluids in continental Rifting
Lee, H; Fischer, T. P; Ranka, L S; Onguso, B; Kanda, I; Opiyo-Akech, N; Sharp, ZD; Hilton, D R; Kattenhorn, S A; Muirhead, J (University of Nairobi, 2013-12-26)The East African Rift (EAR) is an active continental rift and ideal to investigate the processes of rift initiation and the breaking apart of continental lithosphere. Mantle and crust-derived fluids may play a pivotal role ...
