Which minerals are found in basalt and gabbro?
Basalt contains minerals such as plagioclase feldspar, pyroxene, and olivine. Gabbro also contains plagioclase feldspar and pyroxene, but generally has a coarser texture due to slower cooling rates underground.
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 mineral scratches dolomite and is scratched by olivine?
Quartz scratches dolomite, while olivine scratches pyroxene.
What element is principally responsible for making olivine pyroxene amphibole and biotite dark?
Iron is principally responsible for making olivine, pyroxene, amphibole, and biotite dark in color. Iron impurities in these minerals can give them a dark green, black, or brown coloration.
Which mineral will scratch fluorite galena and pyroxene?
Quartz would be able to scratch fluorite, galena, and pyroxene as it is harder than these minerals on the Mohs scale of hardness.
What type of rock is made of only pyroxene and olivine?

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.
Is peridotite composed primarily of olivine and pyroxene?
yes it is made up of olivine and various pyroxenes
