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.
no its the least silica rich of granitic and andesitic magma.
Ultramafic igneous rock contains the least silica.
Yes. Gabbro, an igneous rock, has iron-bearing hornblende and augite.
Felsic igneous rock contains the highest proportion of silica. Granites are felsic igneous rocks.

Bytownite is a form of feldspar, found in lime-rich igneous rock.
rich
No, rhyolite is a silica-rich volcanic or igneous rock.
no its the least silica rich of granitic and andesitic magma.
Ultramafic igneous rock contains the least silica.
An igneous rock with a high level of silica will have a light color.
Yes. Gabbro, an igneous rock, has iron-bearing hornblende and augite.
Felsic igneous rock contains the highest proportion of silica. Granites are felsic igneous rocks.
False. Basalt would be an example of an igneous rock with a low silica content.
Granite
Granite is composed of feldspar, quartz, biotite and muscovite mica. It has a high amount of silica. Granite is an igneous rock.
