The Department of Mineral Sciences maintains a world-class research collection of rocks, minerals and meteorites. Specimens from the research collection are available for loan to researchers, in most cases free of charge.
The research collection includes over 600,000 specimens. Highlights include:
- Historically significant collections, including the Antarctic Meteorite Collection and many former USGS collections
- Samples from difficult- or impossible-to-access locations and events, including historic eruptions, closed mines, and the seafloor
- Rare or unusual rocks and minerals, including many mineral type specimens
