Crustal structure and seismic anisotropy of rift basins in Somaliland.

ABSTRACT: Rift margins provide insights into the processes governing the rupture of the continental lithosphere and the subsequence formation of sedimentary basins. The Proterozoic basement underlying Somaliland has been affected by multiple rifting; however, the crustal structure of these rifted basins remains unknown. This study utilized teleseismic receiver function analysis, Bayesian inversion, common conversion point imaging and 2D forward gravity modelling to examine the crust and upper mantle of Somaliland. The results indicate 36.8-38.2 km of crust in southern Somaliland, while the central and northern regions feature thinned crust (~ 21 km) with 5-6 km thick sediments. The joint analysis of radial and transverse components of receiver functions and shear wave splitting revealed fast axis di
