HT-HS Microfabric Evolution

First transient stage (g < 2):
As in the HT-LS experiments, changes in interference colors result from highly active rotational mechanisms which orient grains´ crystallography more favourably for intracrystalline gliding.

Second transient stage (2<g<8):
Yellow grains grow at the expense of all other grain orientations via grain boundary migration. This results in the formation of a domainal microfabric consisting of yellow and magenta grains.

Steady state (g > 8, not reported in the animation):
A steady state microfabric is maintained in the same manner as in the HT-LS experiments.

Analogy:
The microfabric shows a high analogy to natural quartz mylonites deformed under upper greenschist to amphibolite facies conditions.
