A trishear model for the deformation of the Sudbury Igneous Complex, Canada

Structural controls on the localization of the mineralized Copper Cliff embayment and the Copper Cliff Offset dyke, Sudbury Igneous Complex, Canada

“…Post-cratering events include metamorphism, folding and faulting related to the 1.7-1.6 Yavapai-Mazatzal, the 1.5-1.4 Ga Chieflakian-Pinwarian and the 1.2-1.0 Ga Grenville orogenies (Bailey et al, 2004;Papapavlou et al, 2018Papapavlou et al, , 2017Tschirhart and Morris, 2012). In the study area, the metamorphic facies reaches upper to mid-greenschist (Card, 1978;Fleet et al, 1987) and the crater floor has been tilted from sub-horizontal to 77°NW−45°NW (Dreuse et al, 2010;Grieve et al, 2008) during the folding and thrusting of the SIC (Clendenen et al, 1988;Cowan and Schwerdtner, 1994;Lenauer and Riller, 2017, 2012a, 2012bMilkereit and Green, 1992;Santimano and Riller, 2012).…”
