Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
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.
Do all silicate minerals contain iron?
silicon, oxygen, iron and magnesium
What igneous rock contains mostly pyroxene and olivine?
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
What mineral crystallizes at the highest temperature?
olivine
Is olivine mafic or felsic?
Olivine is a mafic mineral. It is most abundant in ultramafic rocks.
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.
An igneous rock that contains mostly pyroxene and olivine has .?
an ultramafic composition
What elements combine to form pyrite?
A pyroxenite is an ultramafic rock composed mainly by clinopyroxene, orthopyroxene and in minor amount, olivine (less than 40%). Depending of the modal mineralogy, the can be subclassified as orthopyroxenite (90% or more of opx), clinopyroxenite (90% or more than cpx), websterite (10% or less of olivine) and olivine-websterite (10-40% of olivine). Because the composition of these mineral phases is highly variable, pyroxenites have a broad range of compositions, however, they usually tend to have more SiO2 than peridotites.
Which igneous rock out of granite basalt andesite and peridotite has the lowest silica SiO2 content?
Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.
What igneous rock may be formed by fractional crystallization of olivine and pyroxene?
ultramafic
What igneous rock or magma has the lowest silica content?

Where is peridotite found?
Peridotite is a dense, coarse-grained plutonic rock that contains a large amount of olivine. Spinel-bearing peridotites and plagioclase-bearing peridotites are foliated.
Do all silicate minerals contain iron?
silicon, oxygen, iron and magnesium
What is a silicate mineral--malachite pyrite olivine and diamond?
Olivine is a silicate mineral. Diamond is an elemental mineral. Pyrite is a sulfide mineral. Malachite is a carbonate mineral.
What igneous rock contains mostly pyroxene and olivine?
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
What is the geologic classification of olivine?
The mineral olivine is a magnesium iron silicate.
