Ptask:
Thank-you. That is a good question and can be argued upon. Referring to some articles that I have read that have been written on the origin of the Sudbury basin.
On the advocates that support a meteorite theory, it shows evidence of this, by studying the extreme impact of the contamination and the rapid deposition of the formation, and the original circular shape of the Sudbury structure as evidence.
On the origins of a volcanic occurence argue that features fragments and igneous activity, support that predate and postdate the Sudbury event are evidence that the Sudbury structure is the result of prolonged endogenic process.
From what I have read, and discussed with others, it is the meteorite effect, that I tend to agree with, the disposition of the rock formation was much too rapid for this kind of occurence. This again is my opinion, and very general geology.

Regards
G
