Latest Neoproterozoic basin inversion of the Beardmore Group, central Transantarctic Mountains, Antarctica

Article Abstract:

The latest Neoproterozoic basin inversion of the Beardmore Group located at the central transantartic Mountains in Antarctica was examined. The formation of the structure proves that the area has undergone single deformation during the proterozoic to early paleozoic time. The examination reveals the occurrence of Beardmore shortening as a result of the tectonic inversion of East Antarctic marginal-basin strata. The latest Neoproterozoic history affirms that the Ross orogeny is an old postrifting tectonic process in the region.

Synlithification deformation processes of the Cretaceous sediments of the Ivory Coast-Ghana transform margin: a way to detail the margin history

Article Abstract:

Research into the deformation processes that arose during lithification in the Cretaceous sediments of the Ivory Coast-Ghana transform margin is presented. It is concluded that the deformational style is tightly controlled by the extent of lithification of the sediment, with most of the structures seen having developed within a nonlithified sediment.
