Mantle Wavespeed and Discontinuity Structure Below East Africa: Implications for Cenozoic Hotspot Tectonism and the Development of the Turkana Depression

https://doi.org/10.1029/2022GC010775

Boyce, A.; Kounoudis, R.; Bastow, I. D.; Cottaar, S.; Ebinger, C. J.; Ogden, C. S. (August 2023, Geochemistry, Geophysics, Geosystems)

Key Points New seismic data from the Turkana Depression enhances images of East African mantle wavespeed and discontinuity structure Thinnest transition zone in East Africa is below the NW Turkana Depression and is underlain by a mid to lower mantle plume tail Refractory lithosphere in SE Ethiopia governed northern extent of Mesozoic Anza rifting and southeastern limit of flood basaltic magmatism

Active Deformation Constraints on the Nubia‐Somalia Plate Boundary Through Heterogenous Lithosphere of the Turkana Depression

https://doi.org/10.1029/2023GC010982

Musila, M.; Ebinger, C. J.; Bastow, I. D.; Sullivan, G.; Oliva, S. J.; Knappe, E.; Perry, M.; Kounoudis, R.; Ogden, C. S.; Bendick, R.; et al (September 2023, Geochemistry, Geophysics, Geosystems)

Key Points New 1‐D velocity model relocates 1716 earthquakes with local magnitude ranging from 1 to 4.5 and b ‐value of 1.22 ± 0.06 in Turkana Depression Brittle strain localizes in narrow areas overlying uppermost mantle low velocity zones and avoids previously thinned crust of Mesozoic rift We redefine the modern Nubia‐Somalia plate boundary across the Turkana Depression; only a part of the 300‐km‐wide region is active
