Volcanic Rock
Volcanic rock (also called extrusive rock) is one type of magmatic rock (igneous rocks) and is the condensated product of extrusive magma after diagenesis and compaction, which differ greatly from sedimentary rocks in forming conditions, environments, and distribution. From: Unconventional Petroleum Geology, 2013.

New Zealand has three 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: Basalt magma often forms shield volcanoes. Andesite magma often forms cone volcanoes. Rhyolite magma often forms calderas. Depending on how much gas the magma contains, it can also ...

Volcanic and Extrusive Igneous Rocks
Updated on March 07, 2019. Igneous rocks — those which originate from magma — fall into two categories: extrusive and intrusive. Extrusive rocks erupt from volcanoes or seafloor fissures, or they freeze at shallow depths. This means that they cool relatively quickly and under low pressures. Therefore, they are typically fine-grained and gassy.
