Intermediate is a composition between felsic and mafic.

The igneous rock granite silica rich.

Under ideal conditions rock can melt and yield a granite composition at temperatures as low as. Are igneous rocks that are silica deficient but high in iron and magnesium. Derived from the words feldspar and silica to describe an igneous rock having abundant light colored minerals such as quartz feldspars or muscovite. Rhyolite is similar in composition and appearance to granite but it forms through a.

Alkali feldspar granite a granitoid in which at least 90 of the total feldspar is alkali feldspar. Granite is an igneous intrusive rock crystallized at depth with felsic composition rich in silica and predominately quartz plus potassium rich feldspar plus sodium rich plagioclase and phaneritic subeuhedral texture minerals are visible to the unaided eye and commonly some of them retain original crystallographic shapes. Igneous rocks typically consist of approximately 12 major oxides totaling over 99 percent of the rock of the oxides silica sio 2 is usually the most abundant. Magmas richest in sio 2 such as alkali granite granite and tonalite are generally deficient in mgo we term such magmas silicic si rich or felsic contraction of feldspar and silica light colored minerals dominate felsic rocks so many geologists use the term felsic to refer to any light colored igneous rock even if the chemical composition is unknown.

Felsic aphantic igneous rock thus light colored and silica rich with very small grains diorite intermediate phaneritic rock thus small grain texture with a variety of light dark and silica magnesium and iron. Rhyolite is a silica rich igneous rock found throughout the world. Felsic and mafic rocks division of igneous rocks on the basis of their silica content. Igneous rocks are formed from the solidification of magma which is a hot 600 to 1 300 c or 1 100 to 2 400 f molten or partially molten rock material.

Derived from the words magnesium and ferric fe is the chemical symbol for iron to describe an igneous rock having abundant dark colored magnesium or iron rich minerals such as biotite pyroxene or olivine. The rock received its name from german geologist ferdinand von richthofen better known as the red baron a world war i flying ace the word rhyolite comes from the greek word rhýax a stream of lava with the suffix ite given to rocks. Felsic igneous rocks are rich in silica in the 65 75 range meaning the rock would be 65 75 weight percent sio 2 and poor in iron and magnesium. Chemical analyses of the most abundant components in rocks usually are presented as oxides of the elements.

Andesite an intermediate volcanic rock. Aplite a fine grained intrusive igneous rock. Igneous rock any of various crystalline or glassy rocks formed by the cooling and solidification of molten earth material igneous rocks constitute one of the three principal classes of rocks the others being metamorphic and sedimentary.
