Three dimensional gravity modeling of southern Africa
More LessVariations in crustal thickness make a
significant contribution to the Bouguer
gravity field that is largely counterbalanced
by compositionally dominated seismic
velocity variations in the upper mantle.

IGCP Project 474: Images of the Earth’s Crust & Upper Mantle
Authors B. Goleby, L. Brown, R. Stephenson, T. Fomin and D. FinlaysonIGCP Project 474, is jointly funded by UNESCO and IUGS. IGCP Project 474
achieves its objective through its website http://www.earthscrust.org, where
images are available of the interior of the Earth's crust and upper mantle across a
variety of representative structural provinces from all parts of the globe.

The Agulhas-Karoo Transect Seismic Reflection Profile: Revealing Secrets Under the Southern Karoo Basin of South Africa
Authors A.S. Lindeque, T. Ryberg, J. Stankiewicz, M.H. Weber and M.J. de WitOur understanding of the tectonic evolution of the Cape Fold Belt, southern Karoo Basin and associated geophysical
Beattie Magnetic Anomaly (BMA), may be challenged by the new ~ 100 km Near Vertical Reflection (NVR) seismic
image which reveals ~42 to 45 km of complex crust and a sharp crust-mantle transition. The 5 to 10 km upper crust
consists of dipping reflectors interpreted as the folded sequences of the Karoo Basin, underlain by continuous flat-lying
reflectors that represent the Cape Supergroup (CSG) which may contain thrusts.
