Kivesvaara C2 chondrite: silicate petrography and chemical composition
Fragments of the Kivesvaara meteorite were said to have been found in Paltamo, northern Finland in 1968. The chemical and mineral composition and the textural features show that this meteorite is a rare C2 carbonaceous chondrite. The research material consists of two fragments with traces of fusion...
