Intrusive Granite Extrusive Equivalent

Gabbro is a mafic rock and has the same chemistry and mineralogy as basalt.

Intrusive granite extrusive equivalent.

Granite is an intrusive felsic silicic plutonic rock. Granites are light colored with coarse grains. 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. And granite is a felsic rock equivalent to rhyolite. Scoria is a dark colored extrusive volcanic rock with abundant large vesicles. Diorite is an intermediate rock equivalent to andesite.

A felsic coarse grained intrusive igneous rock composed of quartz orthoclase feldspar sodium rich plagioclase feldspar and micas. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. It contains more than 68 weight of silica in composition and is granular and coarse grained in texture. They are primarily formed from continental crust.

Granite is a coarse grained light colored intrusive igneous rock that contains mainly quartz feldspar and mica minerals. What rock has the same composition as granite. Granite the equivalent of its extrusive volcanic rock type rhyolite is a very common type of intrusive igneous rock. Intrusive rocks are classified the same way extrusive rocks are according to the relative amounts of feldspars quartz and ferromagnesian minerals.

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. No granite is the most common intrusive igneous rock. It is the intrusive equivalent of the extrusive rhyolite. Intrusive igneous rocks crystallize below earth s surface and the slow cooling that occurs there allows large crystals to form.

Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite. Granite is classified as a felsic rock high in silica content. Intrusive equivalent of rhyolite. The central cores of major mountain ranges consist of intrusive igneous rocks usually granite.

Very light and will float on water.
