Volcanic tuff in Colac
Volcanic tuff rock has been used in construction since ancient times. Tuff is compacted volcanic material, formed during an eruption when ash and other sedimentary materials settle around the rim and sides of the volcano. These deposits mix with surface conditions, including air, water and lava as it travels and cools, and are compacted into solid rock.
‘Wombat‘ is a local name used for volcanic tuff rock found within Colac and district, and is famous throughout the region. Coragulac Quarries sources wombat by digging up the rim of an extinct volcano.
There is a history of volcanic activity in Colac, and older tuffs have been cemented together by pressure over time. Each new explosion deposited additional materials, leading to the formation of tuff rings and tuff cones.
Volcanic tuff rock is composed of many different materials, depending on the nature of the eruption and the minerals contained in the explosions, as well as natural elements of the surrounding area.
Softer than the scoria our quarry sources in Colac, volcanic tuff rock is ideal to use as an alternative to driveway gravel. It’s also easy to shape into stones for building purposes, like outdoor walls or landscape sculptures.
