What minerals form the rock diorite?
the minerals are olivine and pyroxene ..you're welcome
Are olivine and pyroxene most likely to be found in felsic rock?
No. They are generally found inf mafic 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.

What is an example of a mafic rock?
Mafic rock is an example of igneous rock which is dominated by olivine, silicates pyroxene, mica, and amphibole. Common mafic rock samples are basalt and gabbro.
