Impact or no impact the geology of the Sudbury Basin is consistent with a felsic phreatomagmatic subaqeous volcanigenic depositions like the numerous copper zinc depostits of the Archean. I hold that the low temperature nickel formation and remarkable confinement of the nickel to one contact or layer indicates that it extruded as an aqueous solution and precipitated when it hit seawater, sometimes mixing with overlying volanics and tuffs.

This theory was advanced by some graduate theses in the mid sixties.
