I both collect meteorites and give talks about them throughout the U.S. I am always looking for good books on meteorites that I can recommend to those who attend my presentations. Norton's books, as well as McSween's, are the best. It's chock full of very interesting information that has been abstracted from research journals and put into language that non-specialists can understand. It's by no means a beginners book, but one that you'd want to read after the more superficial ones.The main theme is, of course, identifying the parent planets and asteroids for the classifications of meteorite. McSween provides his readers with the most up-to-date information, by 1999 standards, and when there is no agreement, he offers us his best opinion.The book is organized by first providing a good overview of meteoronics in general. Then he addresses chondrites in Chapter 2, followed by a chapter related to possible parent bodies for the chondrites discussed. Ch 4 and 5 do the same for achondrites, and Chs 6 and 7 for Irons and Stony-Irons. The final two chapters get into subjects such as the geography of teh asteroidal belt and Kirkwood gaps, resonance, fractionations, and so forth -- this is the discussion that will interest those who have been involved with meteors for awhile.I highly recommend the book and hope that he updates it in the near future. It has a 1999 date -- 8 years ago from this review. I'd love to read a third edition.
