This service is the best choice for most suspected Ordinary Chondrites. It includes the following:
Sample Prep - Making of one 25mm probe mount required for microprobe analysis, and one petrographic thin section when needed. These remain with the Institute of Meteoritics for archival and future use.
Type Donation Processing & Management - According to the rules set forth by the Meteoritical Society, 20 grams or 20% of the total known weight of the specimens (TKW), whichever is less, must be donated to an approved repository in order to receive an official name, and have it published in the Meteoritical Bulletin. NMMS will verify, approve, and transfer the Type Donation to the UNM Institute of Meteoritics' Meteoritical Society approved repository.

Microprobe Analysis - Specimen specific analysis determined by the classifying researcher and the microprobe lab manager.
Classification, Write-up & Submission - Synthesis of the microprobe data into an accurate, well formed, and defensible classification for inclusion and submission to the Nomenclature Committee for approval, official name, and publication in the Meteoritical Bulletin.
- Report - A customized comprehensive paper and digital report with USB archive of all assets associated with the sample, analysis, and classification.
There are times when it may be necessary to perform oxygen isotopic analysis, or additional microprobe analysis, in addition to the standard minimum electron microprobe analysis. This is almost never true for ordinary chondrites, unless the initial evaluation was in error. All submissions slated for classification and submission to Nomenclature Committee for official name and publication in the Meteoritical Bulletin, require a minimum of at least the Standard Analysis and Classification service. In most cases this is sufficient.
