Talk:Helium diffusion

Help.

I can't think why the sic should be in the phrase "This helium seeps out of (sic) zircons quickly over a wide range of temperatures." I can't think how it can be correct for a multiple editor situation to need a sic. I could not quickly determine who put it in, and so I can't ask if there is something I did not understand. I removed it but would certainly be willing to see it returned if I do not understand the usage correctly. --John Baab 02:16, 26 February 2009 (UTC)
