Lava solidifies to rock. New Zealand has 3 main types of volcanoes, and each has been formed from a different type of magma. Once the lava has erupted, it cools and solidifies into rock: 1  Basalt magma often forms shield volcanoes. 2  Andesite magma often forms cone volcanoes.asalt is associated with great rock columns that are found in many places around the Earth, for example, the Organ Pipes in Dunedin or the Giantâs Causeway in Ireland. Basalt magma is formed at high temperatures (around 1,200ÂºC). When it comes out of the volcano, it is hot and liquid.
