Article Abstract:
The new data presented by Prave regarding sedimentology in northwestern Namibia particularly the Neoproterozoic Otavi and Mulden groups is not adequate to conclude an early continental collision resulting in foreland orogeny. There is a need to integrate petrographic and geochemical data as well as structural correlations to accurately interpret the data presented by Prave. At any rate, there is no convincing evidence regarding foreland orogeny in the region.

Revised age of the Rockland tephra, northern California: implications for climate and stratigraphic reconstructions in the western United States
Article Abstract:
The Rockland tephra, located in the western US, is a result of a volcanic eruption whose ashflow and pyroclastic material has formed a mass that spans 80 cubic kilometers. This tephra serves as an important marker for climate and stratigraphic constructions. Recent studies have indicated that the recorded age of the tephra has remained largely incorrect. The correct age of the tephra must be recomputed so that other related calculations can be readjusted.
