Read my Introductory Meteoritics series each month in the
Meteorite Times (at www.meteorite.com). I am explaining
the fundamentals in small doses. Also, you may want to see the
U.C.L.A. website on how to identify a meteorite at: http://www.ess.ucla.edu/research/cosmochemistry/meteorite_howto.html;
also, go to http://www.saharamet.com/ to see the
absolutely outstanding website designed by the Pellisons. Look at the
photo gallery and particularly the reference cards that show many meteorites
(both "in situ" and close-ups, and magnified sections of the many
individuals they have found.)
(Careful: AD following :=) I also have available some
excellent books on the subject on my website (or you can buy them elsewhere,
usually at higher prices!)
