Here is an adaptation of wonderful flowchart devised by Debora Rios and colleagues at the Nacional/UFRJ in Brazil. Although deliberately simple, we suspect that most experienced meteorite hunters would have little criticism with the logic.
Please, study this chart before contacting me. If you do contact me, tell me why, on the basis of this chart, you think your rock might be a meteorite. In particular, look at these photos of meteorite fusion crusts: fusion crust | fusion crust 1 | fusion crust 2 If your rock does not have a fusion crust, then I am not going to tell you that it might be a meteorite.
If your rock “passes the test” please do not conclude that you rock IS a meteorite. Passing just means that the rock is worth further evaluation, perhaps a chemical test.
