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
