[meteorite-list] Shocked Quartz Found at Upheaval Dome, Utah

[Paul]

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.”
