Examples of overprintoverprint Most of the island consists of pervasively overprinted, greenschist-facies sequences. Several brittle extensional micro-faults bear a ductile overprint expressed in the folding of both foliation and fault surfaces. In highly sheared regions of the phyllonite, the only evidence preserved is for extension, with any strike-slip fabrics having been entirely re-worked and overprinted. This is mainly due to the penetrative last overprint under greenschist-facies conditions, which erased all relic features of foregoing events. Exact metamorphic conditions during the last overprint are difficult to constrain, due to the lack of suitable petrological tools for greenschist-facies mineral assemblages. Such anomalously low values can be attributed to overprinting by isotopically light cements precipitated during diagenesis of the organic-rich intervals. Our studied samples were most likely affected by several metamorphic overprints, such as burial, regional and/or contact metamorphism. The diorites exhibit primary igneous features (including local orbicular structures) and show no penetrative deformational overprint. Part of the pervasive silicification was then brecciated and overprinted by advanced-argillic alteration. Occasionally, old ripple faces with symmetrical oscillation ripples are overprinted by plentiful traces. This relationship suggests that overprinting deformations were consistently focused into the hangingwall of the fault zone. Both sets cross-cut the entire nappe pile and overprint all previous structures. Minor structural development may be evaluated in terms of regional strain profiles and overprinting relationships. This growth of pargasite and oligoclase indicates further retrogression to upper amphibolite facies conditions following the high-pressure granulite facies overprint. Apparently, minerals oriented favourably, that is, subparallel with shear surfaces, were most easily overprinted by shearing. These examples are from corpora and from sources on the web.
