What else can I help you with?
Is quartz monzonite mafic or felsic?
Quartz monzonite ranges from intermediate to felsic.
What minerals are common in both felsic and marfic igneous rocks?
Biotite and muscovite micas, quartz, magnetite, olivine, amphiboles, and feldspars.
Which igneous rock is composed of coarse grained crystals of quartz feldspar and mica?
Felsic igneous rocks (the lightest in color) are comprised mostly of quartz and potassium feldspar. Intermediate igneous rocks (somewhat darker than felsic) are made up of some quartz and potassium feldspar, but mostly plagioclase feldspar.
What mineral composition is most characteristic of felsic rocks?
Felsic rocks are typically composed of minerals such as quartz, potassium feldspar, plagioclase feldspar, and muscovite mica. These minerals are light in color and have lower densities compared to mafic rocks.
Is pegmatite felsic or mafic?
Pegmatite is classified as felsic due to its composition which is rich in silica and aluminum, containing minerals such as quartz, feldspar, and muscovite. Mafic rocks, on the other hand, have a higher content of iron and magnesium-rich minerals like pyroxene and olivine.
Is quartz monzonite mafic or felsic?
Quartz monzonite ranges from intermediate to felsic.
What minerals are common in both felsic and marfic igneous rocks?
Biotite and muscovite micas, quartz, magnetite, olivine, amphiboles, and feldspars.
Is quartz mafic?
No, quartz is not mafic. Mafic minerals are rich in magnesium and iron, while quartz is a silicate mineral composed of silicon and oxygen. Quartz is classified as a felsic mineral due to its composition and low mafic content.
Which igneous rock is composed of coarse grained crystals of quartz feldspar and mica?
Felsic igneous rocks (the lightest in color) are comprised mostly of quartz and potassium feldspar. Intermediate igneous rocks (somewhat darker than felsic) are made up of some quartz and potassium feldspar, but mostly plagioclase feldspar.
What rocks are felsic?
Granite, rhyolite, and pegmatite are examples of felsic rocks. These rocks are light in color and have high silica content, making them rich in minerals like quartz and feldspar. Felsic rocks are associated with continental crust and are often found in areas with volcanic activity.
Which pair of minerals is most likely to be found in felsic rock?
Quartz and feldspar are the most likely pair of minerals found in felsic rock. Felsic rocks are rich in silica, which forms minerals like quartz, and feldspar is another common mineral found in these rocks.
What mineral composition is most characteristic of felsic rocks?
Felsic rocks are typically composed of minerals such as quartz, potassium feldspar, plagioclase feldspar, and muscovite mica. These minerals are light in color and have lower densities compared to mafic rocks.
What is the density of felsic rocks?
Felsic refers to igneous rocks that are rich in elements that form feldspar and quartz. Their densities vary, depending on the rock, but they generally have low density.
Is pegmatite felsic or mafic?
Pegmatite is classified as felsic due to its composition which is rich in silica and aluminum, containing minerals such as quartz, feldspar, and muscovite. Mafic rocks, on the other hand, have a higher content of iron and magnesium-rich minerals like pyroxene and olivine.
What are two examples of felsic rock?
Granite and rhyolite are examples of felsic rocks. These rocks are generally light in color and rich in minerals like quartz, feldspar, and mica. They are formed from the crystallization of magma with high silica content.
Quartz and potassium feldspar grains are the main constituents of which rock?
Granite is the rock composed mainly of quartz and potassium feldspar grains.
Do felsic rocks crystallize at lower temperatures?
Yes, felsic rocks crystallize at lower temperatures compared to mafic rocks. This is because felsic rocks have higher silica content, leading to the formation of minerals like quartz and potassium feldspar that require lower temperatures to crystallize.
