Gold and Uranium and that some of the Ir concentrations may be attributable
to microbes as well.<


Rob Van der Voo suggested several years ago that an Ir anomaly found in 
algal laminates deposited near the F/F from the Canning Basin was the result
of concentration of Ir by microbes.  I don't have the specific reference 
handy, but I believe it appeared in Geology.
