 I think the list has taken this thread well and answered a lot of the =
questions. It is interesting how terminology can be misunderstood, such =
as oxidation, its just not only rust!
But,I think the most perplexing question has that of classifications. =
Since the researchers are somewhat divided as of yet on some classes as =
to where they should be placed or categorized, it makes for a lively =
topic. And I'm sure as equipment becomes more refined and techniques to =
define minerals become larger in numbers, those classes will become even =
more a subject of debate. Right now we have isotopes on one side and =
physical mineralogy on the other and often they clash, or so it appears =
to me, and one is usually favored over the other for a definitive ruling =
on where a meteorite falls within a class. The other measure used is =
metal content. And this puzzles me somewhat as metals are a later =
forming element ( even though I've heard that some physicists consider =
any element other than Hydrogen or Helium a metal). And require some =
fractionation to occur before they are evolved out of solution. That it =
takes a sun to form before the heavier elements are even formed. This =
brings up the Aluminum isotopes used for initial heat of early =
planitismals. When is it formed and how is it formed so early on? And =
why is only the Aluminum isotopes ( Al26 I think) a source of internal =
heat mentioned. This is one of the things I haven't read about ( having =
only read Dodd, Wasson, Sears and one other that I just can't remember =
how his name is spelled but its like Ramdhor or something about opaque =
minerals in meteorites) and maybe that's what I need to read, so if =
someone on list knows of a book which covers the formation of basic =
elements a little better in how and when they formed early on, I catch =
up on the big picture.=20

Have enjoyed these topics very much and thanks to all for contributing
Mark

  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.=20

  So lets go...

they are red. Go figure?=20

        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?
