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.
classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
What igneous compositions has the lowest silica content mafic ultra mafic intermediate or felsic?
Ultra mafic rocks have the least amount of silica.
Coal felsic or mafic?
Neither. The terms mafic and felsic apply to silicate igenous rocks. Coal is neither igneous nor is it composed of silicates. Coal is an organic sedimentary rock.
What minerals are common in both felsic and marfic igneous rocks?
Biotite and muscovite micas, quartz, magnetite, olivine, amphiboles, and feldspars.
What minerals are present in felsic rocks and mafic rocks?
Felsic refers to igneous rocks that are relatively high in silica and aluminum. Mafic refers to igneous rocks that are higher in magnesium and iron than felsic rocks.
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.
Is rock salt felsic or mafic?
Neither. The terms mafic and felsic refer to the composition of igneous rocks, which are dominated by silicate minerals. Rock salt is a sedimentary halide rock. Such terms do not apply to it.
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 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 coal mafic or felsic?
It is neither mafic or felsic, as these terms refer to the composition of igneous rocks, whereas coal is a sedimentary rock.
What is a Precambrian's shield?
How are mafic and felsic igneous rocks different
classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
Are all rocks either mafic or felsic?
No. First of all, the terms mafic and felsic generally only apply to igneous rock. even among igneous rocks, mafic and felsic are just ranges on a "spectrum" of composition. Other classifications and examples include ultramafic (peridotite), intermediate (andesite), and intermediate-felsic (dacite).
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.
What two methods are used to group igneous rocks?
Igneous rocks can be either intrusive or extrusive, based on their location upon solidification from magma. Igneous rocks can also be grouped by chemistry and mineral content as felsic, intermediate, or mafic, mainly on the abundance of silicate minerals that are present.
Is pumice in a example of a mafic igneous rock?
No. Pumice is usually intermediate or felsic. The mafic equivalent of pumice is scoria.
