Karoo-Etendeka Unconformities in NW Namibia and their Tectonic Implications
… crustal doming associated with Etendeka flood volcanism. The enhanced tectonism during the Early Cretaceous controlled accommodation space for the alluvial-fluvial and aeolian deposits of the lower Etendeka Group. Disconformities within those deposits and the overlying lava succession …

The Origin and Petrogenesis of the Ethiopian Flood Basalts
… plume source responsible for a major continental flood basalt event and the manner in which it interacted with the lithosphere over the course of continental separation. The flood basalts of the Ethiopian Plateau constitute the larger part of this province and are associated with melting in the …

Application of platinum-group element (PGE) geochemistry to select geological problems
… Earth, and (ii) the products of Siberian Traps flood volcanism. The Ir concentrations and Re/Ir in sediments are a sensitive indicators of the presence or absence of an extra-terrestrial component. Analyses of multiple end-Permian sediment samples from four locations in China and Japan for …

Detektion eines mesozoischen Gangschwarmes in NW Namibia und Rekonstruktion regionaler Spannungszustände während der Südatlantiköffnung
Gangschwärme nehmen eine bedeutende Stellung im Verständnis zur kontinentalen Fragmentierung ein. Einerseits markieren sie das Paläo-Spannungsfeld und helfen bei der Rekonstruktion der strukturellen Entwicklung der gedehnten Lithosphäre, andererseits gibt ihre petrologische Beschaffenheit Aufschluß …
