“…The results of the 2007 expedition to Lindi confirm the major features of the geological map presented by Nicholas et al (2007), but also suggest the need for a number of modifications (Figs. 2 and 3).…”

“…A major transgression during the Late Cretaceous caused widespread deposition of mudstones in offshore environments of the Mandawa and Rovuma basins that persisted into the Paleogene. A modern review of the tectonic history of coastal Tanzania can be obtained from Nicholas et al (2007), with reference to deposition during the Late Cretaceous-Neogene. Also, Key et al (2008) recently revised the lithostratigraphy of the Mesozoic and Cenozoic successions of the Rovuma basin in northern coastal Mozambique.…”

“…Based on scarce sediment exposures and TDP cores, Nicholas et al (2006Nicholas et al ( , 2007 indicated that Upper Cretaceous and younger rocks strike NNW-SSE across Lindi bay, with younger sediments outcropping to the NE. The area is dominated by Kitulo Hill, a strike ridge that follows Maastrichtian-Paleocene sediments along its crest.…”

“…It has already been established that the stratigraphical development of the Rovuma Basin is directly related to the 'progressive' break-up of south-western Gondwana and Cenozoic intracontinental tectonism associated with the East Africa Rift System (Salman and Abdulah, 1995;Nicholas et al 2006Nicholas et al , 2007.

They note that a passive margin developed along coastal Kenya and Tanzania in mid-Cretaceous times (to coincide with the split of Madagascar from India and the opening of the Mascarene Basin at about 93 Ma) and persisted until the early Miocene (Kent et al, 1971;Collins, 2003;Nicholas et al, 2006).…”

The offshore East African Rift System: Structural framework at the toe of a juvenile rift

et al. 2015

The Cenozoic East African Rift System (EARS) extends from the Red Sea to Mozambique. Here we use seismic reflection and bathymetric data to investigate the tectonic evolution of the offshore branch of the EARS. The data indicate multiple and time transgressive neotectonic deformations along~800 km of the continental margin of northern Mozambique. We observe a transition from a mature rift basin in the north to a juvenile fault zone in the south. The respective timing of deformation is derived from detailed seismic stratigraphy. In the north, a~30 km wide and more than 150 km long, N-S striking symmetric graben initiated as half-graben in the late Miocene. Extension accelerated in the Pliocene, causing a continuous conjugate border fault and symmetric rift graben. Coevally, the rift started to propagate southward, which resulted in a present-day~30 km wide half-graben, approximately 200 km farther south. Since the Pleistocene, the rift has continued to propagate another~300 km, where the incipient rift is reflected by subrecent small-scale normal faulting. Estimates of the overall brittle extension of the matured rift range between 5 and 12 km, with an along-strike southward decrease of the extension rate. The offshore portion of the EARS evolves magma poor, similar to the onshore western branch. The structural evolution of the offshore EARS is suggested to be related to and controlled by differing inherited lithospheric fabrics. Preexisting fabrics may not only guide and focus extension but also control rift architecture.
