Ordinary chondrite (L6)
Fell, 8 April 1928, 17:15 hrs; 367.5 g

A small stone fell and was recovered. Olivine (Fa25.3) and low Ca-orthopyroxene (Fs21.4) compositions are characteristic of the L-chondrite geochemical group. Mineralogically the meteorite consists primarily of olivine and orthopyroxene accompanied by minor albitic plagioclase, troilite, and Fe-Ni metal. Accessory chromite and other minor opaques (copper, ilmenite and isocubanite) have also been reported. Chemical analysis suggests that other mineral phases may also be present. However, in the mid 20th century such phases would not always have been readily detected — even with larger meteorites — using the destructive wet-chemical techniques used in decades following the meteorite's fall. Chromite aggregates appear to be the product of pre-terrestrial shock. A Pb,Th:He gas release age of 3.21 Ga is probably another indication of at least one major post-formational collision.

The L-group of ordinary chondrites (relatively low in total iron) are the largest group of classified witnessed meteorite falls and account for ~45% of all well-classified meteorite falls. The L6 petrologic type account for ~ 70% of the group. 272 meteorite falls are currently classified exactly as 'L6' chondrites [June 2017].

189 g, approximately half of the original mass, has been kept at the Australian Museum in Sydney.
