Ebook Download | O. Richard Norton, Lawrence Chitwood, "Field Guide to Meteors and Meteorites" | This is a magnificent book and a must for anyone who is interested in our solar system and its formation. How do you study something that took place 4.6 billion years ago? You look at the unaltered debris that is left over from that period and fortunately for science that debris can be found on Earth in the form of meteorites. Once they are cut open, their extraterrestrial origins are betrayed and they become a history lesson to the scientists who study them. That's why this book is so important - it tells you what to look for, as most meteorites are found by amateurs - and it may as well be you. This is one of the very few areas where a non-scientist can make a real contribution to the scientific understanding of our planet's origins.
The book itself is divided into three parts. The first part is devoted to all the debris floating around the solar system, from interplanetary dust particles (IDPs), to asteroids, to meteoroids which become meteorites once they land on Earth. Meteors are the luminous phenomenon we have all witnessed in the night sky. Next comes the second and main part of the book with its description of the different classes and subclasses of meteorites, replete with color photos of whole specimens, slices, and thin sections. Every category of meteorites tells a different story that relates to the particulars of its formation. While most meteorites are of asteroidal origin, some have come from the Moon and Mars. These latter can send the heart racing if you are lucky enough to stumble upon one.
The final part of the book is about how to find meteorites and `what next?' if you think you have indeed stumbled upon one. Firstly, don't worry as they are neither hot to the touch nor are they radioactive. A gallery of `meteorwrongs' is included to show that a rock can look like a meteorite in some respects and yet sadly be terrestrial. A wonderful segment is included on what meteorites look like in thin section and it is a glorious world indeed. This is where former ugly-ducklings become superstars of science. Not everyone knows this, but you can actually buy these extraterrestrial rocks from space (just Google `meteorites for sale'). If you do, or if you wish to find you own, or if you just wish to learn more about the environment our Earth inhabits, you will want a copy of this outstanding book. The reader should be warned though - meteorites have been found to be highly addictive.
