To List: I have been collecting for a couple of years, but I still do not understand how you identify a meteorite with reasonable confidence. There are a lot of NWAs for sale that are not particularly valuable, I suppose, so they are not sent to the lab for definitive identification. How can you tell this is a meteorite? Assume it is slightly magnetic, dark, but without classic fusion crust. I am trying to educate myself about rocks, but photos of the inside of olivine basalts look very much like meteorites that I have seen. How would I tell the difference? Basically, for the experts and dealers, how do you know? When is the evidence enough to send for analysis? A tougher question is when do you suspect a lunar or martian sample? I have researched the books (except the new Norton which I do not have yet); I have searched the internet, but I just can't find a satisfying answer. Aren't terrestrial rocks sometimes slightly magnetic, also? I really would appreciate any help anybody can give me on the subject.
