What type of rock may be formed by fractional crystallization of olivine and pyroxene.?
A mafic rock, such as gabbro or basalt, may be formed through fractional crystallization of olivine and pyroxene. Mafic rocks are characterized by their high content of magnesium and iron, which are common components of olivine and pyroxene minerals.
An igneous rock that contains mostly pyroxene and olivine has .?
an ultramafic composition
What minerals form the rock diorite?

Is basalt an element a mineral or a rock?

What is Earth's mantle made from?
It is made from a rock type known as Peridotite.Peridotite is an ultramafic dense, coarse-grained igneous rock consisting mostly of the minerals olivine and pyroxene containing less than 45% silica.

What are miner rocks?
Rocks are made of minerals. Only a few minerals are rock forming and most rock is made from a combination of the commonest of these such as feldspars, quartz, mica, olivine, calcite, pyroxene and amphiboles.

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.
