Lava is the name given to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling and this formation cools and solidifies much quicker than intrusive igneous rocks The quicker cooling forms rocks that are smooth and fine grained and we use these rocks to create STEAKSTONES

The Cornubian Batholith The granites were intruded towards the close of the Variscan Orogeny over a time period extending from 300 275 Ma late Carboniferous Permian Mineralogically they are two mica granites meaning they contain muscovite and biotite plus quartz K feldspar and plagioclase alkali granites On the whole they are coarse grained and in places are pegmatitic

Thus plutons include dikes laccoliths batholiths sills and other forms of intrusions Most plutons are thought to be the result of igneous activity in which a magma is involved the controversial origin of some large granitic bodies however requires that metasomatic processes or granitization be included when discussing many plutons

Igneous rocks are those that form via the process of melting and cooling If they erupt from volcanoes onto the surface as lava they are called extrusive contrast Intrusive rocks are formed from magma that cools underground If the intrusive rock cooled underground but near the surface it is called subvolcanic or hypabyssal and often has visible but tiny mineral grains
