Eagles Nest

Central Australia

Found Summer 1960

Stone. Olivine achondrite (brachinite)

A stone of 154 g was found by a prospector "next to an eagle's nest" in Central Australia. It is an oriented meteorite with a complete fusion crust. The main constituent is cumulate olivine, Fa32. It contains Cr-spinel, Cr/(Cr+Al) 0.82, Mg/(Mg+Fe) 0.18, a Ca-phosphate, sulfides, and high-Ca pyroxene, Wo45En45Fs10 (Kring et al., 1991). Information and research material, W. V. Boynton, University of Arizona, Lunar and Planetary Laboratory, Tucson, Arizona 85721, USA. Although there are mineralogical differences, it is possible that Eagles Nest is another stone of Brachina, which was found in central South Australia (A. W. R. Bevan, Western Australian Museum, Perth, Western Australia, pers. comm.). However, Nehru et al. (1992) maintain that Eagles Nest is not paired with Brachina, because they are different in mineralogy, chemistry and average grain size. The main mass is with Robert Haag, P. O. Box 27527, Tucson, Arizona 85726, USA.
