Is Granit Intusive Or Extrusive

The central cores of major mountain ranges consist of intrusive igneous rocks usually granite.

Is granit intusive or extrusive.

Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Br br as a result you won t be able to see them as individual. Granite is a coarse grained light colored intrusive igneous rock that contains mainly quartz feldspar and mica minerals. Granite is the best example of intrusive rocks whereas the basalt is a fine example of extrusive rocks.

Examples of intrusive rocks include granite gabbro and pegmatite. Granite is an intrusive rock that it is formed deep beneath the earth s surface. The lava cools much faster on the surface so the minerals either form crystals that are too small to see easily or else it forms a volcanic glass with no crystals at all. It contains more than 68 weight of silica in composition and is granular and coarse grained in texture.

Its principal minerals are feldspars quartz and mica. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock. Notice the large grains of pink white and gray minerals. Extrusive rocks are formed outside of the earth s surface.

Granite is a coarse grained light colored intrusive igneous rock that contains mainly quartz feldspar and mica minerals. The central cores of major mountain ranges consist of intrusive igneous rocks usually granite. Granite is an intrusive type of igneous rock also since it is intrusive it cools very slowly and forms large crystals and coarse large grained igneous rock. The specimen above is about two inches five centimeters across.

Basalt by zureks cc by sa 3 0. If the magma forces its way to the surface it is then called lava which cools and hardens into extrusive rocks. Granite is a common intrusive rock. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock.

It s advisable to be keen when purchasing granite granite is used in different industries ranging from antiquities to engineering. Intrusive rocks are made up of enormous crystals whereas extrusive rocks have tiny crystals that can be seen only with a microscope.
