Classification Services Discontinued 3/15/06

Effective immediately, NAU's electron microprobe laboratory will no longer able to offer meteorite identification/classification services to the general public. We are sorry that this is the case, but we are unable to meet the increased demand for this service. See here for some initial information about meteorite identification. If after carfully condifering this informaiton, you still think you may have a meteorite, we suggest that you contact Cascadia Meteorite Laboratory for testing.
