Basalt, on the other hand, gets its name from the Latin word “basanites,” which means very hard stone. It is composed mainly of plagioclase feldspar, pyroxene, and sometimes olivine or amphibole.

· Olivine is another critical mineral in basalt classification. In alkali basalt, it is commonly present instead of Ca-poor pyroxene. In olivine tholeiites, it is present in company with Ca-poor pyroxene. By adding olivine, our basalt model has grown to four minerals: plagioclase, two pyroxenes, and olivine.
