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.
3 main groups of igneous rocks?
Felsic, mafic, and intermediate (by chemistry). Also intrusive, extrusive, and porphyritic (by method of formation and visible texture).
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
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.

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.

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.

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.
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.
What is the difference between felid and mafic?
Felsic rocks have 0-15% mafic crystals, while mafic rocks have 46-85% mafic crystals.
Is a limestone mafic?
No. The terms mafic and felsic apply to igneous rocks. Limestone is a sedimentary/biochemical rock and so cannot be said to be mafic, felsic, or intermediate.
