Felsic magma is very viscous, meaning it resists flowing. Because of this it is difficult for it to be channeled through the crust to erupt from a volcano, so instead it usually cools underground.

∙ 9y agoIn the 1800s, when scientists were becoming more aware and more formal about geology, names of Greek gods were often used to name things.
Hence, volcanic rock that pushed up underground, and had a rounded top was named after Pluto. Therefore, it is referred to as plutonic rock.
A different process was named after the Greek God Neptune, and items meeting this requirement are called neptunic. And so on.

Are felsic rocks usually intrusive or extrusive?
Most felsic rocks, though not all, are intrusive.
Is pegmatite felsic or mafic?
It is felsic because it is lightly colored. Most rocks that are light are also felsic. The exception is obsidian which is dark and felsic.
What are the names of a plutonic solid?
Solid plutonic rocks are intrusive igneous rocks such as granite and gabbro.
Large plutonic rocks called?
the large plutonic rocks formed by the hardening of magma into the earths crust is called the ignius rocks
What are plutonic features?
Plutonic rocks are intrusive rocks that feature magma that has cooled underground in chambers, or plutons. Plutonic has large crystals that are well formed. Gabbro and granite are included in the coarse-grained plutonic.
How was rock created?
By solidification of felsic plutonic bodies underground.

Are plutonic rocks igneous rocks that hardened on top of volcanoes?
No. Plutonic rocks are igneous rocks that hardened underground. Rocks that form on volcanoes are volcanic rocks.

What rocks are felsic?
Felsic rock are igneous rocks that are rich of quartz, orthoclase and plagioclase minerals. Here is the list of felsic rocks: granites, rhyolites, aplites, and pegmatites.
What minerals are present in felsic rocks and mafic rocks?
Felsic refers to igneous rocks that are relatively high in silica and aluminum. Mafic refers to igneous rocks that are higher in magnesium and iron than felsic rocks.
