Scientific paper

The lower crust around the Kenya Rift is generally reflective in wide-angle seismic sections. Remarkably, high amplitude reflections of low frequency originate from underneath the rift, whereas weaker reflections of high frequency prevail from outside the rift. This indicates thicker layering and larger reflection coefficients in the lower crust beneath the rift than outside it. Petrologically, magmatic intrusions are compatible with the thick layering beneath the rift axis, and the associated large reflection coefficients are indicative of their cumulate layering and fractionation. Hence, the observed thinning of the crust below the rift may be substantially less than the real mechanical thinning due to the addition of intrusive or underplated material.
