Mount Wellington

Mount Wellington ( Māori: Maungarei ) is a volcano of Aucklandfeldes in the same suburb of the city of Auckland on the North Island of New Zealand. It is located about 10 kilometers southeast of the city center.

The 135 -meter-high Vulkanist the youngest volcano of Aucklandfeldes on the mainland and second youngest of Aucklandfeldes. He is the greatest volume of cinder cones in Auckland, but lower than the Mount Eden ..

Its activity phase was about 9000 years ago. Since the volcanoes of the Aucklandfeldes tend to not break again by the end -time activity, it is assumed that also the Mt Wellington is probably extinct.

The mountain consists of a base of tuff of previous eruptions, which was covered by slag and lava. The main cone was formed by three main vents, chimneys further brought forth lava flows that nearly 6 km long, extending towards Manukau Harbour.

The volcano has expelled 160 million cubic meters of lava and 9.2 million cubic meters of ash and tuff.

The mountain was by early settlers after Arthur Wellesley, 1st Duke of Wellington named. The Māori use the mountain for several centuries for a Pā ( fortified village ). They called him Maunga -a- Reipae ( 'Watchful mountain " or " mountain of Reipae "an ancestor of the Tainui ).

Much of the lava flows around the mountain was mined for the production of industrial granules. The Lunn Ave quarry north- west of the summit was the largest gravel quarry supplied in 1988, nearly 7 % of New Zealand aggregates in road construction. The quarry was closed and is opened up for residential development.

Leachate of the volcano is collected in Penrose, 5 km away as process water for industrial purposes.
