The Ivuna (CI1) meteorite fell on 16 Dec 1938. A single stone of 704.5 g was recovered of the 2 or 3 which fell. Ivuna is the prototype for the CI (Ivuna-like) Carbonaceous Chondrites. It is one of 5 known CI falls and 4 CI finds. At the present time all 9 CI chondrites are classified as having petrologic type CI1.
Like all carbonaceous chondrite, Ivuna and other CI carbonaceous chondrites have nearly solar Mg/Si ratios and similar oxygen isotope ratios. In addition, Ivuna and other members of the CI chemical group are distinguished by the absence of chondrules and a high degree of hydration.
Because of Ivunaβs very small mass, other more massive CI1 falls (such as Orgueil) are more frequently utilized for research.
