Abstract
The continental margins of Namibia and Argentina belong to the Large ligneous Provinces (LIPs) of the earth (Hinz et al. 1994). These volcanic types of continental margins are<br>characterized by volcanic structures that are 5 to 10 km thick and approximately 100 km wide and lower crustal seismic Vp-velocities of 7,2 - 7,6 km/s. The hitherto known very large volcanic units of the south Atlantic continental margins were possibly formed within a relatively short time span of only a few million years.
