Is felsic porphyritic extrusive?
Some felsic rocks are and some are not. The term felsic is a description of an ingeous rock's composition, not its texture or where it occurs.
What rocks are felsic?
Felsic rock are igneous rocks that are rich of quartz, orthoclase and plagioclase minerals. Here is the list of felsic rocks: granites, rhyolites, aplites, and pegmatites.
What has a more felsic composition rhyolite or basalt?
Rhyolite has a more felsic composition than basalt.
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.
What does the word felsic?
The word felsic is used to describe igneous rocks that are rich in silica and alkali feldspar. Such rocks tend to be light in color and have a lower density than other igneous rocks.
Is pegmatite felsic or mafic?
It is felsic because it is lightly colored. Most rocks that are light are also felsic. The exception is obsidian which is dark and felsic.
Does Krakatoa have felsic magma or mafic?
felsic
Where did felsic lava get its name?
The term felsic des derived from feldspar and silica, which are the primary components of felsic rock.
Is Felsic a Intrusive or Extrusive Rock?
It can be either. The term felsic describes the composition of the rock, not where it forms. The general category for intrusive felsic rock is granite while extrusive felsic rock is rhyolite.
Is felsic porphyritic extrusive?
Some felsic rocks are and some are not. The term felsic is a description of an ingeous rock's composition, not its texture or where it occurs.
Is felsic magma viscous?
Yes. Felsic magma is very viscous.
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 quartz monzonite mafic or felsic?
Quartz monzonite ranges from intermediate to felsic.
What are two examples of felsic rock?
Granite and rhyolite are examples of felsic rock.
Is felsic magma eruptive?
Not usually. Because it is so viscous, felsic magma does not erupt as easily as mafic magma. While eruptions of felsic magma do occur, most felsic rocks are intrusive, meaning they solidify underground.
Is felsic lava thick?
Felsic lava is a slower moving lava, with high silica content. Most felsic lava deposits as granite, granite, muscovite, and orthoclase.
