Early Proterozoic activity on Archean faults in the western Superior province - evidence from pseudotachylite Early Proterozoic activity on Archean faults in the western Superior province - evidence from pseudotachylite
Late Archean granitic plutons (∼2700 to 2665 Ma; U-Pb zircon) of the Superior structural province are cut by a variety of brittle discontinuities, including joints, fractures, and faults, the latter of which show evidence of cataclasis and meter to tens of meters displacements. Fluid circulation, alteration of wall rocks, and neomineralization of epidote, actinolite, and chlorite...
