Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).

Rocks are categorized into three distinct types based on their method of formation. The three types are igneous, sedimentary, and metamorphic. Early in Earth's history, all rock was igneous, having formed from the cooling of melt on the surface.

An igneous rock is simply a rock that has solidified from magma or lava upon cooling. Igneous rocks can be intrusive (solidified from magma underground) or extrusive (solidified from lava at or near the surface). The bulk of Earth's crust is formed from igneous rock. Examples of igneous rock include basalt, obsidian, rhyolite, granite, diorite, gabbro, and pumice.

A sedimentary rock is one that is formed by the accumulation of small to large sediment particles derived from all three types of rock and in some cases organic material, and undergoes compaction, cementation, or evaporation from/precipitation from a saturated mineral solution. Sedimentary rock is classified as organic, (derived from organisms), clastic (formed from any size particle of preexisting rock), or non-clastic (also referred to as chemical), where the sedimentary rock is formed from the evaporation of a solution that is saturated with mineral compounds. Examples of organic sedimentary rocks are coal and limestone. Examples of clastic sedimentary rocks are conglomerate and shale. Examples of non-clastic or chemical sedimentary rocks are rock gypsum and rock salt.

A metamorphic rock is an igneous, sedimentary, or another metamorphic rock that has either been squeezed by incredible pressures deep underground and/or has been exposed to very high temperatures, altering its structure, mineral alignment, or chemical composition. Metamorphic rocks are classified as contact (from proximity to a magmatic intrusion) or regional (resulting from deep burial and pressures from plate collisions Metamorphic rock is also classified as foliated or non-foliated, foliation being the parallel alignment of the constituent minerals in bands that are perpendicular to the applied pressure. Metamorphic rocks can also be described by the grade of metamorphism which has taken place from low to high, high being the closest to the next stage in the rock cycle, melting. Examples of metamorphic rock are slate, quartzite, marble, phyllite, schist, and gneiss..

The three major types of rocks are sedimentary, metamorphic, and igneous.

Because they are so hard, Igneous rocks make useful road building materials. When sheets of igneous rock are cut and polished, they are used inside buildings such as banks and offices, and are also used as gravestones. There are different types of igneous rock, therefore each type has its own uses, such as: Granite: Used for long lasting monuments, for trim and decoration on buildings. Pumice: Because they are so light, it is used quite often as a decorative landscape stone. If grounded to a powder, it is used as an abrasive in polish compounds and in Lava soap. Crystalline Igneous rocks can be used for jewelery and other similar things. Countertops and building stone. Lava soap, building materials, landscaping

There are several types of cutting methods and apparatus depending on what type of cut you need. Diamond tip blades are usually used for cutting sections of a granite countertop. There is also a method called "Waterjet" which involves a high pressure jet of water travelling across the stone and effectively slicing through the surface. Very intricate shapes can be cut through this process , but it can be a slow and expensive way. Jason MD Mistermarble www.mistermarble.co.uk

If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.

Igneous rock can be found on the surface in areas of current or past volcanism or in uplifted and eroded areas of past plutonic intrusions, deep underground nearly anywhere, or in areas of past or present glaciation, where igneous rock has been eroded and deposited.

Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
