Classification Services Discontinued 3/15/06

Effective immediately, NAU's electron microprobe laboratory will no longer able to offer meteorite 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. We suggest that you contact one of these labs for testing: Cascadia Meteorite Laboratory or Washington University in St. Louis Meteorite Laboratory.

We will continue to perform classification work for established long-term collaborators and attempt to continue to update/improve this web site.
