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.
