Mark,

If you look hard you will find dozens of decent sites that will help one =
understand meteorites alot better. Also, Nortons new book goes alot =
further than Rocks From Space, and it is filled with colored pictures =
demonstrating the differences in their appearance. It is called The =
Cambridge Encylcopedia of Meteorites, and is highly recommended. Another =
very in depth book is Meteorites and Their Parent Planets by Harry =
McSween, Jr. To read it and understand (most of) it takes great patience =
and focus...good luck. Another interesting (online) source of =
information and pictures is the Dweir Studies. The link to it is below. =
There are other books, sites that others may refer you to that are =
helpful.

http://www.geocities.com/~dweir/

Have fun...it takes awhile to get the full depth. I've studied it quite =
a bit and I still get turned around on ideas and concepts.

  Subject: [meteorite-list] Beginner Questions on Meteorite =
Classification

  I am a beginning collector and have read Norton's Rocks from space. I =
am wondering if there is any online definition of the currently used =
classification system as it differs from the system described by Norton. =
Specifically when a meteor is classified as a H, L or LL of 3.X with a =
weathering of Y and a shock rating of Z. Where would one find the =
definition of X, Y and Z?
  =20
  =20
  Second question, are there any online photographs that show the =
comparision of 4, 5, and 6. I am a big fan of unclassified NWA's and =
would like to get some feel for what these meteors are?
  =20
  Last question if I wanted to learn more about the technical side of =
the hobby, what would be good reading material on or off line. I am =
looking to go alot deeper than Norton.
  =20
  Thanks All
