2015: Brittle-viscous deformation of vein quartz under fluid-rich low greenschist facies conditions. Solid Earth 6, 681-669.Kjoll, H.J., Viola, G., Menegon, L., Sorensen, B.E., 2015. Brittle-viscous deformation of vein quartz under fluid-rich low greenschist facies conditions. Solid ...
Non-uniform distribution of Al between the three symmetrically equivalent Si sites in low quartz is converted to a random distribution by dry or hydrothermal annealing above 400-degrees-C due to Al-Si exchange, as shown previously by EPR measurements. Rate equations for the Al-Si exchange are ...
