[meteorite-list] Did Giant Salt Lakes Cause Permian Mass Extinction ???

[Paul]

New Theory On Largest Known Mass Extinction In Earth's 
History: The largest mass extinction in the history of 
the earth could have been triggered off by giant salt 
lakes, whose emissions of halogenated gases changed the 
atmospheric composition so dramatically that vegetation 
was irretrievably damaged, Science Daily, March 31, 2009,

New theory on largest known mass extinction in the history 
of the earth. Did volatile halogenated gases from giant 
salt lakes at the end of the Permian Age lead to a mass 
extinction of species?
