Intrusive Granite Extrusive Equivalent

What rock has the same composition as granite.

Intrusive granite extrusive equivalent.

Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock. Some cool so quickly that they form an amorphous glass. Its principal minerals are feldspars quartz and mica. Gabbro is a mafic rock and has the same chemistry and mineralogy as basalt.

No granite is the most common intrusive igneous rock. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. And granite is a felsic rock equivalent to rhyolite. The high silica and low iron and magnesium contents result in crystallization of mostly non ferromagnesium silicate minerals k feldspar na plagioclase and quartz.

Granite is an intrusive felsic silicic plutonic rock. For example a magma that would form rhyolite if it vented at the surface would crystallize into a granite in a subterranean chamber kilometers below the surface. It commonly forms as a bubble rich upper surface on many basalt and andesite lavas. Diorite is an intermediate rock equivalent to andesite.

Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Granite is a coarse grained light colored intrusive igneous rock that contains mainly quartz feldspar and mica minerals. They are primarily formed from continental crust. Very light and will float on water.

Intrusive rocks are classified the same way extrusive rocks are according to the relative amounts of feldspars quartz and ferromagnesian minerals. It is the intrusive equivalent of the extrusive rhyolite. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form.

Rhyolite is the extrusive equivalent in chemistry and density of granite. Granite is classified as a felsic rock high in silica content. The central cores of major mountain ranges consist of intrusive igneous rocks usually granite. Granites are light colored with coarse grains.

Scoria is a dark colored extrusive volcanic rock with abundant large vesicles.
