Orgueil is a CI1 carbonaceous chondrite meteorite that fell near Orgueil in southern France on 14 May 1864. CI chondrites are chemically primitive, fine-grained rocks rich in hydrated minerals and organic compounds, and their nonvolatile elemental abundances closely resemble those measured in the so...
Ivuna is a CI1 carbonaceous chondrite that fell near Ivuna, Tanzania, in 1938. CI meteorites are rare, chemically primitive materials whose nonvolatile elemental abundances closely resemble those measured in the Sun, although their minerals have been extensively altered by water on their parent body...
Alais is a CI1 carbonaceous chondrite that fell near Alais, now called Ales, in southern France in 1806. CI meteorites are chemically primitive, rich in hydrated minerals, and notable for elemental compositions that closely resemble the nonvolatile composition of the Sun, although their original tex...
Revelstoke is a CI1 carbonaceous chondrite that fell near Revelstoke, British Columbia, Canada, in 1965. Only about one gram of material was recovered, leaving exceptionally little material available for scientific analysis or collecting. As a witnessed CI fall, it represents a rare class of chemica...
