| | The Polar Rock Repository (PRR) provides curatorial preservation and lending of geologic samples from polar regions along with associated materials such as field notes, maps, raw analytical data, paleomagnetic cores, thin sections, microfossil mounts, microslides and residues. Additional services include magnetic susceptibility, intensity and specific gravity measurements. The PRR acquires collections through donations from institutions and scientists and then makes these samples available as no-cost loans for research, education and museum exhibits. Rock samples searches and loan requests can be made online through the PRR website. |
