[oxytropidoceras at cox.net]

There is a new paper published in the November 2009 issue of Geology 
that argues that the Sudbury Impact in Canada ended the creation of 
Banded Iron Formations during the Precambrian.

The paper is

Slack, J. F. and W. F. Cannon, 2009, Extraterrestrial demise of banded 
iron formations 1.85 billion years  ago. Geology. vol. 37, no. 11, pp. 1011-1014, 
doi:10.1130/G30259A.1
