The formation of fine grained, well mixed
(ultra)mylonitic layers in the upper mantle is still an open question. Here, microfabrics
displaying porphyroclast mixed assemblage transitions were analyzed regarding
their phase assemblage, grain size and shape, mixing patterns and
crystallographic orientations for insights into the interplay of phase mixing
and recrystallization.
