This growth of pargasite and oligoclase indicates further retrogression to upper amphibolite facies conditions following the high-pressure granulite facies overprint.
Minor structural development may be evaluated in terms of regional strain profiles and overprinting relationships.
Both sets cross-cut the entire nappe pile and overprint all previous structures.
This relationship suggests that overprinting deformations were consistently focused into the hangingwall of the fault zone.
Occasionally, old ripple faces with symmetrical oscillation ripples are overprinted by plentiful traces.
Part of the pervasive silicification was then brecciated and overprinted by advanced-argillic alteration.
The diorites exhibit primary igneous features (including local orbicular structures) and show no penetrative deformational overprint.
Our studied samples were most likely affected by several metamorphic overprints, such as burial, regional and/or contact metamorphism.
