Slate is classified as a metamorphic rock, and it does not fall into the categories of felsic or mafic, which are terms primarily used for igneous rocks based on their silica content. However, slate is typically derived from shale, which can be made up of both felsic and mafic minerals. The mineral composition of slate can vary, but it generally contains more quartz and clay minerals, leaning toward a felsic composition.
What else can I help you with?
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 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 quartz monzonite mafic or felsic?
Quartz monzonite ranges from intermediate to felsic.
Is mauna kea mafic or felsic?
As a shield volcano, Mauna Kea erupts mafic lava.
Is mauna loa mafic or felsic?
The 1980 eruption of Mount St. Helens produced dacite, which has an intermediate-felsic composition.
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 quartz monzonite mafic or felsic?
Quartz monzonite ranges from intermediate to felsic.
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.
