Mount Warrnambool
Encyclopedia
Mount Warrnambool is a single large scoria cone volcano
that is 216 metres (709 ft) high. Mount Warrnambool is 16 kilometres (10 mi) south west of Terang
, Victoria, Australia. It is visible from the Princes Highway
on the way to Warrnambool.
The last eruption was over 5,000 years ago.
Lava and tuff
also form layers in the area. The tuff forms a partial ring that wraps around the east and north side of the volcano. The ring of tuff could be on other sides of the volcano too, except that it is covered in lava. The tuff has been quarried on the north side of the Princes Highway. The tuff here is hardened, but was formed due to volcanic ash
falling from the air. Structures visible in the quarry include a base surge, and volcanic bomb
sag.
The basalt below the tuff has been dated at 2.2 Ma. A basalt layer on top of the tuff was dated at 0.57 Ma.

Lava and tuff
Tuff
Tuff is a type of rock consisting of consolidated volcanic ash ejected from vents during a volcanic eruption. Tuff is sometimes called tufa, particularly when used as construction material, although tufa also refers to a quite different rock. Rock that contains greater than 50% tuff is considered...

Volcanic ash
Volcanic ash consists of small tephra, which are bits of pulverized rock and glass created by volcanic eruptions, less than in diameter. There are three mechanisms of volcanic ash formation: gas release under decompression causing magmatic eruptions; thermal contraction from chilling on contact...

Volcanic bomb
A volcanic bomb is a mass of molten rock larger than 65 mm in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. They cool into solid fragments before they reach the ground. Because volcanic bombs cool after they leave the volcano, they do not have grains...
