Ordinary chondrite (H6; S3; W2-3)
Fell, 17 July 1902; 11.3 kg

Just after an explosion had been heard, a whizzing sound followed as a meteoritic stone struck the ground. Picked up while still warm, the somewhat friable stone — largely covered by its fusion crust — revealed a light grey, fine-grained interior. Olivine [Fa-18.1], pryoxene, troilite, and Fe-Ni metal were identified as its major components. Lesser amounts of chromite, copper, phosphate, and other minor sulfides have also been reported. The meteorite has been classified has an H chondrite and an Ar-Ar formational age of ~4.4 Ga reported. Phosphates have been especially studied as parts of various solar system chronology studies which suggest that many ordinary chondrites may have been subject to several disruptive heating events, esp. during the solar system's first billion years or so.

The H chondrites (relatively high in total iron) are the second largest group of ordinary chondrite falls and represent ~40% of classified witnessed falls with the H6 petrologic type representing ~25 % of all H chondrites. As of late November 2016, exactly 94 meteorites had been classified as an 'H6' ordinary chondrite by the Meteoritical Society. The main mass has been kept at the Australian Museum in Sydney.
