The synformal geometry of the 1.85 Ga Sudbury Igneous Complex (SIC), an impact melt sheet resulting from largemagnitude meteorite impact, attests to post-impact deformation. However, in contrast to the overlying Onaping Formation, a heterolithic impact melt breccia, the SIC shows little evidence for pervasive ductile strain. This pertains in particular to its NE-lobe characterized by a curvature of about 100° in plain view. This curvature has been interpreted either as a fold or as a primary… CONTINUE READING
