COVER: Oblique view of crudely folded sandstone injectite breccia overlying the Clachtoll fault (northwest Scotland) located just above the yellow meter ruler. The breccia formed as an ~250 kt megaclast of Archaean Lewisian basement gneisses fell onto, and overpressured, wet sediments of the Mesoproterozoic Stoer Group, possibly following an earthquake at ca. 1.2 Ga. The local shortening represented by the Clachtoll fault and overlying fold likely occurred immediately following impact, as the megacalst slid sideways to the left prior to its passive burial below younger sandstones of the basal Stoer Group, which are visible in the background. See “A bigger splat: The catastrophic geology of a 1.2-b.y.-old terrestrial megaclast, northwest Scotland” by Killingback et al., p. 180–184.Photo by: Richard Walker
