Scientific paper
Deformation lamellae are found in quartz grains throughout the Rooiberg Group, Transvaal Sequence of the Bushveld Complex, a proposed impact structure. Occurrence of these lamellae in the Rooiberg felsites indicates formation after crystallization of this unit and precludes generation at the same time as a hypothesized impact melt represented by the Rooiberg Group. These features are similar to deformation lamellae in quartzites adjacent to a shear zone in the Kuopio-Kinahmi area, Finland and are significantly different from planar deformation features (PDFs) in quartz associated with hypervelocity impact. These features are the result of localized tectonic processes that were active throughout the region and are not indicative of meteorite impact.
