Notes on Australian meteorites
Abstract
A review of Australian meteorites, eliminating paired falls, gives a total of 184, comprising 67 irons, 9 stony-irons, and 108 stones (6 anchondrites and 102 chondrites); 10 of these were observed falls. Olivine and pyroxene compositions have been determined by microprobe analysis for most of the chondrites, and they have been examined microscopically and classified according to the Van Schmus-Wood classification. Additional data on mineral compositions are given for the enstatite achondrite Mt Egerton and the ureilites North Haig and Dingo Pup Donga; a bulk analysis of a small sample of the eucrite Emmaville has been made. Ringwoodite and majorite are recorded from the Coolamon meteorite, the third occurrence of these meteorite minerals. A list of Australian irons and stony-irons, giving Ni and Ge contents, structural type, and Ge-Ga class has been compiled, and the Ni-Ge data presented in a diagram.
