What else can I help you with?
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 granite mafic?
No, granite is not considered mafic. It is an igneous rock that is classified as felsic due to its high silica content and lower concentration of iron and magnesium minerals compared to mafic rocks like basalt.
What are the terms felsic and mafic used by geologists to describe?
They are descriptive terms as to the relative silica content of igneous rocks. Igneous rock which is high in silica is referred to as felsic. Igneous rock which is relatively low in silica is referred to as mafic.
Is quartz monzonite mafic or felsic?
Quartz monzonite ranges from intermediate to felsic.
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 amphibolite mineral a felsic mafic or intermidate?
Is mineral amphibolite a felsic, mafic or intermidiate in term of color
Is the oceanic crust felsic or mafic?
Oceanic crust is mafic.
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.
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.
Between mafic lava and felsic lava which flowsfaster?
Mafic lava is hotter than felsic lava and therefore flows faster.
What is the comaprison of felsic and mafic?
Felsic minerals are Silicon-rich; whereas Mafic ones are low in Silicon, but contain Iron and Magnesium.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
Does the mantle have mafic or felsic in it?
The mantle is ultramafic.
What are the 2 kinds of rock?
Mafic and felsic.
