Japan’s Antarctic Meteorite Collection earns global recognition as IUGS Geo-collection

Research Organization of Information and Systems
Grant and Award Announcement

The Antarctic Meteorite Collection at the National Institute of Polar Research (NIPR) in Japan has been recognized as a Geo-collection by the International Union of Geological Sciences (IUGS). An IUGS Geo-collection is a museum collection of global importance because of its particularly high scientific, historical, or educational relevance for geological sciences. With over 17,400 meteorites, the Antarctic Meteorite Collection offers invaluable insights into the early solar system, planetary bodies, the Moon, and Mars. Carefully classified and stored, these samples complement space mission findings, advancing global research on planetary evolution and solar system history.
