Exempel på overprint

• Most of the island consists of pervasively overprinted, greenschist-facies sequences.

• Two generations of folds can be distinguished by overprinting relations.

• 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.
