Petrology and Geochemistry of Early Cretaceous Bimodal Continental Flood Volcanism of the NW Etendeka, Namibia. Part 2: Characteristics and Petrogenesis of the

As a result of their relative concentration towards the respective Atlantic margins, the silicic eruptives of the Parana (Brazil)---Etendeka large igneous province are disproportionately abun-dant in the Etendeka of Namibia. The NW Etendeka silicic units, dated at 132Ma, occupy the upper stratigraphic levels of the volcanic sequences, restricted to the coastal zone, and comprise three latites and five quartz latites (QL). The large-volume Fria QL is the only low-Ti type. Its trace element and isotopic signatures indicate massive crustal input. The remaining NW Etendeka silicic units are enigmatic high-Ti types, geochemically different from low-Ti types. They exhibit chemical affinities with the temporally overlapping Khumib high-Ti basalt (see Ewart et al. Part 1) and high crystal-lization temperatures (980 to 1120C) inferred from augite and pigeonite phenocrysts, both consistent with their evolutio
