The Kangean and Kediri, Indonesia meteorites

Abstract

Two meteorite falls in Indonesia were described and classified. Kangean has Fe/Si= .73, olivine Fo= 17.5 with 1.7 Percent Mean Deviation, paucity of clinopyroxene, plagioclase, and glass and with weakly undulose olivine, and is classified as H5b. Mineralogically Kediri is unshocked and shows virtually no signs of metamorphic reequilibration although the mineral chemical evidence is ambiguous. Classification of Kediri as L3a is proposed. Kediri contains grains that may have survived chondrule formation without melting, and shows evidence for hot accretion.
