Re: [meteorite-list] Serious question?

Thanks Mark,

I guess my point was it a big planet. Mars and the moon aren't puny either. Lots of different mineralogies if you could get a closer look.

 

So lets go...

When I go into Yosemite the cliffs are grey. When I am in Zion they are red. Go figure?

On a similar note ... why is the Lunar surface Grey and Mars red if
they are both resurfaced by meteorites, likewise wouldn't we expect
other rocky bodies/planets to be red too especially those with a thin
atmosphere? Surley the only process that would turn meteorite dust into
red soil is oxygen or WATER ??

Any thoughts?

Hello List, Scientists are now thinking that mars is red from meteorite
dust, right? They also say tons of meteorite dust are landing on earth,
right?
I was wondering if the black iron stuff we get on our magnets when we
drag them through the dirt could me meteorite related?
Thanks, Tom
