Story: Rock, limestone and clay

Quarries (1st of 2)

Quarries

Auckland’s largest quarry, on Mt Wellington, has mined the lava flows of this volcanic mountain’s cone. More than 30 million tonnes of basalt have been blasted, dug up and crushed to form aggregate. Basalt has been used in the construction of many Auckland buildings and roads, but has resulted in the destruction of this and other volcanic cones.
