dc.description.abstract | <p> Small shear zones located northwest of the Grenville Front Mylonite Zone exhibit both a brittle and ductile deformation history. Textures reveal that an earlier mylonitic rock has been overprinted by one which demonstrates textures typical of brittle cataclasis.</p> <p> ductile deformation has occurred under greenschist facies conditions, while a later, brittle event has occurred below lower greenschist temperatures. These produce high shear strain values which lie between 14.44 and 10.79.</p> <p> Upper and lower age limits for the initiation of shear zones have been determined as being prior to the emplacement of pegmatite dykes, and up until the formation of brittle-ductile shear zones found locally. Thus, they have developed between 1400 ± 50 Ma and approximately 1100 + ? Ma.</p> | en_US |
