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.
What are intermediate rocks?
are a mixture of both mafic and felsic rocks
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.
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.
Why are mafic rocks denser than felsic rocks?
Mafic rocks have higher concentrations of dense minerals like iron and magnesium compared to felsic rocks, which are rich in lighter minerals like quartz and feldspar. This difference in mineral composition contributes to the higher density of mafic rocks.
Why are felsic rocks melted by mafic magmas but mafic rocks are not melted by felsic magmas?

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.
What minerals are present in felsic rocks and mafic rocks?
Felsic rocks are primarily composed of minerals like quartz, feldspar, and muscovite, while mafic rocks contain minerals such as olivine, pyroxene, and plagioclase. Felsic rocks have lighter-colored minerals and lower density compared to mafic rocks, which have darker-colored minerals and higher density.
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.
What are intermediates?
are a mixture of both mafic and felsic rocks
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.
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 rocks denser than felsic rocks?
Mafic rocks have higher concentrations of dense minerals like iron and magnesium compared to felsic rocks, which are rich in lighter minerals like quartz and feldspar. This difference in mineral composition contributes to the higher density of mafic rocks.
What are the terms felsic and mafic used by geologists to describe?
Geologists use the terms felsic and mafic to describe the compositions of igneous rocks. Felsic rocks are rich in silicon and aluminum, making them lighter in color and less dense. Mafic rocks are richer in magnesium and iron, making them darker in color and denser.
