Australia: The Land Where Time Began

A biography of the Australian continent 

This is a large composite scoria cone overlying lava flows. The summit is dome-shaped with no major crater. At the summit there is an 8 m deep spatter vent, 1 m wide at the entrance, on the summit, a rare feature of Victorian eruption points. 2 prominent parasitic vents are present, the large one near the base on the southerstern side, the smaller one being on the northeastern flank. On the western slope are outcrops of alternating layers of lava and scoria, with country rocks from the Ordovician imbedded in the ejecta. In the volcanic ash perfect augite crystals up to 1 cm long have been found. A radial network of gullies have been established on the slopes. The deeper and broader ones are believed to have been formed by avalanches on oversteepened sides of scoria during eruption. On the southeastern slope there is a small scoria pit that produces small amounts, operates intermittently.

It is one of the largest eruptions of the Victorian Central Highlands
