Abstract: Petrological and geothermobarometric data from (garnet)-spinel peridotite and pyroxenite xenoliths in Quaternary alkali-basalts at Mega (Sidamo region, Ethiopia) provide evidence for refertilization and thinning of the lower subcontinental lithospheric mantle (SCLM) during Tertiary rifting events… read more here.

DOI: 10.1016/j.tecto.2018.03.010
Abstract: Abstract We evaluate the frictional strength of seismogenic faults in the Main Ethiopian Rift (MER) by inverting the available, well-constrained earthquake focal mechanisms. The regional stress field is given by − 119.6°/77.2°, 6.2°/7.6°, and 97.5°/10.2°… read more here.

DOI: 10.1016/j.tecto.2018.03.013
Abstract: Abstract Twenty-six paleomagnetic sites in basalt and trachyte flows and ignimbrite deposits sampled in the Dofan magmatic segment, Main Ethiopian Rift (MER). From each site, 6 to 8 core samples were collected. The samples were… read more here.
