| dc.description.abstract | The Wabigoon subprovince is a 900 km long by 150 km wide Archean-aged granite
greenstone belt. Large, synvolcanic batholiths with smaller late to post-tectonic stocks cut the
numerous greenstone belts of the subprovince. One of the post-tectonic stocks is the Taylor Lake
Stock, located within the western Wabigoon subprovince with a late Archean crystallization age
that has been interpreted to infer the cessation of regional tectonics in the area. However, granitoids
are highly competent and dry rocks that are difficult to deform, leading them to appear
undeformed/unmetamorphosed in the field even though they may have undergone ductile
deformation, brittle deformation and associated hydrothermal/metasomatic alteration. In this
study, field mapping and sampling, petrographic analysis, mineralogical compositional analysis,
stable isotope geochemistry and cathodoluminescence imaging of twelve granitoid plutons
(including the Taylor Lake Stock) across the subprovince are used to constrain the relationship
between the brittle deformation, ductile deformation and alteration of the plutons to provide insight
into the tectonic history of the Wabigoon subprovince. [...] | en_US |
