Here's an idea about the "silver" blotches on some of the West
meteorites. Could it be pure nickel? I don't know if it's possible
for metallic particles in meteorites to consist of mostly
nickel. Are all iron/nickel blebs a homogeneous mix of the two
metals? The color of this "silver" blotching looks a lot like matte
nickel plating that is often found on firearms and some plumbing fixtures.
Just a thought.
Best,
John

I really don't know what to make of it. In this new piece, its like
its a silver blob that melted and oozed out of the tiny gash in the
stone. I'm disinclined now to a post fall chemical reaction. Do
take note of the oxidation effect the rain had on the stone.
There is another specimen with silver 'blotches' on this page, the
29.5g piece.

Any good theories out there?
