What minerals are common in both felsic and marfic igneous rocks?
Biotite and muscovite micas, quartz, magnetite, olivine, amphiboles, and feldspars.
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.
Does Krakatoa have felsic magma or mafic?
felsic
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.

How are the minerals biotite mica and the Muscovite mica different?
Biotite mica contains iron and/or magnesium, but muscovite mica does not.
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.
Does Krakatoa have felsic magma or mafic?
felsic
What is muscovite mica's dominant type of breakage?
Muscovite mica is primarily broken by fracturing.
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.
Does rhyolite have a more mafic composition than basalt?
Rhyolite is not a mafic rock, but a felsic rock, high in silicates, and similar to granite in composition.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Is amphibolite mineral a felsic mafic or intermidate?
Is mineral amphibolite a felsic, mafic or intermidiate in term of color
Is granite mafic?
NO it is felsic
Is the oceanic crust felsic or mafic?
