Is peridotite felsic mafic intermediate or ultramafic?
Ultramafic
3 main groups of igneous rocks?
Felsic, mafic, and intermediate (by chemistry). Also intrusive, extrusive, and porphyritic (by method of formation and visible texture).
classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
This type of magma has low silica content?
There are three types of magma that contains silica. Basaltic Magma has 50 percent silica, Andesitic Magma has 60 percent silica, and Granitic Magma has 70 percent silica.
How are igneous rocks classified acording to their..?
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
What is ultamafic?
Ultramafic is a term used to describe igneous rocks made solely of mafic minerals.
Is peridotite felsic mafic intermediate or ultramafic?
Ultramafic
Does the mantle have mafic or felsic in it?
The mantle is ultramafic.
What has the author F P Lesnov written?
F. P. Lesnov has written: 'Rare earth elements in ultramafic and mafic rocks and their minerals' -- subject(s): Ultrabasic Rocks, Rare earth metals 'Plagioklazy poligennykh bazit-giperbazitovykh plutonov' -- subject(s): Alkalic igneous rocks, Plagioclase, Ultrabasic Rocks 'Rare earth elements in ultramafic and mafic rocks and their minerals' -- subject(s): Ultrabasic rocks, Rare earth metals
What is the difference in ultramafic rocks and mafic rocks?
Ultramafic rocks like peridotite and dunite, are igneous rocks that have a very low silica content and very high levels of iron and magnesium. They are therefore more dense than most igneous rock and are found at great depth but appearing on the surface due to volcanic eruption.
What is the igneous rocks that cool quickly on the surface?
Extrusive igenous rocks. The main types are: Komatite/picrite (ultramafic) Basalt (mafic) Andesite (intermediate) Rhyolite (felsic/silicic)
Is peridot a igneous rock or is it something else?
Peridot is gem quality olivine. Olivine is a mineral, not a rock. It is found in mafic and ultramafic igneous rocks.
Is a marble rock ultramafic?
No. Mafic, felsic, and related terms apply to silicate igneous rocks. Marble is composed of carbonates, so such terms do not apply.

classificatio of igneous rock?
felsic, intermediate, mafic, and ultramafic.
Minerals in igneous rock?
Felsic rocks mostly contain silicates such as feldspars and quartz, mafic rocks are ferrromagnesian, containing mostly pyroxene and olivine, ultramafic rocks only contain pyroxene and olivine, and rocks neither felsic nor mafic mostly contain plagioclase feldspar, biotite mica, and amphibole.
