Geoarchive, Geochronology, Geochemistry

MBMG’s Geoarchive database contains records of rock and sediment specimens collected and archived for geologic investigations, including field mapping and economic geology research. Geochronology and geochemistry datasets linked to a specific sample are provided if available. The specimens are stored in a repository on the MBMG campus and are readily accessible.


These materials represent the contents of the Geoarchive database at the time and date of retrieval. These data are considered unpublished and are subject to correction and review. If citing unpublished data please refer to date of download.
