Is peridotite composed primarily of olivine and pyroxene?
yes it is made up of olivine and various pyroxenes
What are three main rocks found on this planet?
The three main rocks found on this planet are sedimentary, igneous, and metamorphic.
How does silica from molten material affect the color of igneous rock?
The majority of minerals associated with igneous rocks are silicates. It is the proportion of certain silicate minerals that affects the color of igneous rocks. Igneous rocks that are high in orthoclase feldspar, quartz, and muscovite mica will be lighter in color than igneous rocks that are higher in olivine, pyroxene, amphibole, and biotite mica.
Does basalt have sodium in it?
No. Calcite is not an igneous mineral. Basalt primarily consists of pyroxines and plagioclase with some olivine.
What is Ultrabasic Igneous Rock?
Ultrabasic is a general term, probably first used by J.W. Judd in 1881, applied to igneous rocks containing little or no feldspar and characterized essentially by the abundance of one or more common mafic minerals such as olivine, pyroxene, and amphibole. Chemically, the rocks contain
What type of rock may be formed by fractional crystallization of olivine and pyroxene.?
Peridotite.
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.
Which minerals are found in the igneous rocks gabbro and basalt?
Olivine and Pyroxene

Which minerals crystallize early in Bowen's reaction series?
Amphibole, plagioclase feldspars, olivine, pyroxene, and biotite mica have the highest crystallization temperatures.
What type of rock is made of only pyroxene and olivine?
Peridotite is made only of olivine and pyroxene
Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?
Minerals which contain much magnesium and iron, like olivine and pyroxene.
Which igneous rock is dark colored cooled rapidly on earths surface and is composed mainly of plagioclase feldspar olivine and pyroxene?
scoria
What is the composition of the Earth lower mantle?

What does dolerite mean?
A dolerite occurs in dikes and sills. These are dark, medium-grained igneous rocks that are typically containing olivine, plagioclase, and pyroxene.
Which is a coarse-grained igneous rock composed of mainly pyroxene plagioclase feldspar and olivine?
Gabbro.
