[meteorite-list] Shocked Quartz Found at Upheaval Dome, Utah
Buchner, E., and T. Kenkmann, 2008, Upheaval Dome, Utah, USA: Impact origin confirmed. Geology. vol.36, no. 3, pp. 227-230. In part, this abstract stated: “In this study, we document, for the first time, shocked quartz grains from this crater in sandstones of the Jurassic Kayenta Formation. The investigated grains contain multiple sets of decorated planar deformation features. ... The shocked quartz grains were found in the periphery of the central uplift in the northeastern sector of the crater, which most likely represents the cross range crater sector.” http://www.gsajournals.org/perlserv/?request=get-abstract&doi=10.1130%2FG24287A.1 Yours, Paul H.

really makes me wonder how much shocked quartz could be found as "background". I am not saying that about this study, but from a curiosity.

Matt - In a study we did several years ago, we found one shocked quartz grain per 7000-12000 grains in various sedimentary rocks and glacial tillites.
