Well it gives me a hint on the valence state of the iron.-Not (III)

An interesting compound that scoured the early Earth: > > http://wattsupwiththat.com/2012/06/27/green-rust-in-earths-early-ocean-history/#more-66... - with your last postI understand sort of what is happening here. We have a hydrated iron (II)/(III) hydroxide that is a 'biological' precursor to magnetite (Fe3O4). This precursor compound is particularly good at scavenging everything fromm solution (albeit likely at trace levels). Almost certainly magnetite will be thermodynamically more stable. -We can make magnetite hydrometallurgically (abiotically) and there are patents for the scavenging properties of said magnetite (and no doubt its intermediates) from an environmental point of view. I am having trouble of getting excited about this.-You have stepped into my world David. Welcome.-rom

I can offer no more. My background is biochemistry. And that was years ago.
