Dave: From: Isotopic evidence for a single impact melting origin of the Sudbury Igneous Complex, A.P. Dickin it al., "Based on the available isotopic and geochemical data, it is suggested that the SIC resulted from a single impact melting event that gave rise to the whole complex entirely from crustal sources." IE: no bolide material survived the impact.
Hope this helps.
