Is granit intusive or extrusive.

Basalt by zureks cc by sa 3 0. The specimen above is about two inches five centimeters across. Extrusive rocks are formed outside of the earth s surface. Notice the large grains of pink white and gray minerals.

Granite is a coarse grained light colored intrusive igneous rock that contains mainly quartz feldspar and mica minerals. 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. Intrusive rocks are made up of enormous crystals whereas extrusive rocks have tiny crystals that can be seen only with a microscope.

I have been in the granite business for many years and have worked my way up from an installer helper to an installer and then a countertop business owner. Its principal minerals are feldspars quartz and mica. The central cores of major mountain ranges consist of intrusive igneous rocks usually granite. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock.

Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock. 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. Granite is an intrusive rock that it is formed deep beneath the earth s surface. The central cores of major mountain ranges consist of intrusive igneous rocks usually granite.

Peridotite is a coarse grained intrusive igneous rock that is composed almost entirely of olivine. Granite is the best example of intrusive rocks whereas the basalt is a fine example of extrusive rocks. If the magma forces its way to the surface it is then called lava which cools and hardens into extrusive rocks. Examples of intrusive rocks include granite gabbro and pegmatite.

Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock.
