… We observed a major network of late Cenozoic canyons and channels on both the East
African and Madagascan margins and in the Western Somali Basin. Accumulations of sediment
on the Madagascan and East African margins total 5+ and 8+ km, respectively, for Middle
Jurassic to Holocene time. … development of the continental margins bordering the Western
Somali and Comoros Basins have become available in the past 15 years; the aim of this study
is to synthesize these new data with previous results and document the geologic evolution of …

The geologic evolution of the conjugate sedimentary basins and margins produced during
the early breakup of Gondwanaland by the relative motion between Madagascar and Africa
is reconstructed utilizing interpretations drawn from outcrop, industrial onshore drilling, Deep
Sea Drilling Project (DSDP) offshore drilling, Lamont-Doherty multichannel seismic (MCS)
data, and single-channel seismic data. Herein we present (1) maps displaying lithological
columnar sections for Karroo (Permo-Carboniferous through Early Jurassic) to Quaternary …
