How about a large iron impacting the Northern hemisphere of Mars
creating an impact basin now filled by lava and mud.
The iron impactor disintegrated and spread iron all over the planet in
a fallout cloud and created a layer of iron rich

My knee-jerk reaction to that is to think about the large iron meteorites

Hey List, I got it figured out! The large Iron the disintegrated must have

Interesting points!
I think the temperature on mars might also have something to do with the
existence of iron rich 'red soil', frost thaw frost thaw for billions of
years, would create a fine dust, in its self would it not?
Anyone fancy
Hi, Steve, and all,
When you are talking about a large impactor, the physical properties of the
impactor material become entirely irrelevant. By the time you get up to a
one-kilometer diameter impactor, or a ten-kilometer diameter impactor, it
wouldn't matter whether the impactor was made of
, but they are topographic
cousins in any case.

Nope. I call that, as will any chemist you ask, an
oxidation-reduction reaction. Oxidation is the loss of electrons,
nothing more nothing less.

Hi, Tom,
Every year the Earth receives tens of thousands of tons of
extraterrestial dust. Most of it is ablated from meteorites entering the
atmosphere, but a small amount is cometary, and solar system dust, and even
a smidge of interstellar dust.
The best place to find it is in deep

Maybe not, if you have the right kind of planet, namely one with an
