Is sandstone felsic or mafic?
Neither. The terms mafic and felsic refer to the composition of igneous rocks, which are dominated by silicate minerals. Marble is a metamorphic rock composed of carbonate minerals. The terms mafic and felsic do no apply to it.
Why are mafic minerals dark in color?
No. Felsic rocks are light-colored and high in silica. Mafic rocks are generally dark-colored and low in silica.
Is rock salt felsic or mafic?
Neither. The terms mafic and felsic refer to the composition of igneous rocks, which are dominated by silicate minerals. Rock salt is a sedimentary halide rock. Such terms do not apply to it.
What is the mafic mineral and felsic mineral?
First of all there is no such thing as a mafic or a felsic "mineral". There can be mafic and felsic rocks.Mafic rocks have a high magnesium and iron content.Felsic rocks enriched with lighter elements such as oxygen and silicon.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Minerals which contain much magnesium and iron, like olivine and pyroxene.
Why are mafic rocks denser than felsic rocks?
Mafic rocks are denser than felsic rocks because they contain heavier compounds, minerals and other materials, they are ferromagnesian in composition.
Is sandstone felsic or mafic?
Neither. The terms mafic and felsic refer to the composition of igneous rocks, which are dominated by silicate minerals. Marble is a metamorphic rock composed of carbonate minerals. The terms mafic and felsic do no apply to it.
Why are mafic minerals dark in color?
No. Felsic rocks are light-colored and high in silica. Mafic rocks are generally dark-colored and low in silica.
Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
Is rock salt felsic or mafic?
Neither. The terms mafic and felsic refer to the composition of igneous rocks, which are dominated by silicate minerals. Rock salt is a sedimentary halide rock. Such terms do not apply to it.

Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
What are some examples of felsic and mafic rocks?
Granite and grandiorite are two felsic rocks but I'm seeing that some people cosider granite mafic.
What are intermediate rocks?
are a mixture of both mafic and felsic rocks
What is the difference in density in mafic rocks in relation to felsic rocks?
Mafic rocks, such as those found in the oceanic crust, are more dense than the felsic rocks found in the continental crust.
Minerals in igneous rock?
Felsic rocks mostly contain silicates such as feldspars and quartz, mafic rocks are ferrromagnesian, containing mostly pyroxene and olivine, ultramafic rocks only contain pyroxene and olivine, and rocks neither felsic nor mafic mostly contain plagioclase feldspar, biotite mica, and amphibole.
