Basalt Rock Formation, Properties, Composition, Uses

Apr 10, 2018 Basalt is rich in iron and magnesium and is mainly composed of olivine, pyroxene, and plagioclase. Most specimens are compact, fine-grained, and glassy. They can also be porphyritic, with phenocrysts of olivine, augite, or plagioclase. Holes left by gas bubbles can give basalt a

Basalt Wikipedia

Geologists classify igneous rock by its mineral content whenever possible, with the relative volume percentages of quartz, alkali feldspar, plagioclase, and feldspathoid (QAPF) being particularly important. An aphanitic(fine-grained) igneous rock is classified as basalt when its QAPF fraction is composed of less than 10% feldspathoid and less than 20% quartz, with plagioclase making up at least 65% of its feldspar content. This places basalt in the basalt/andesite field of the QAPF diagram. Basalt is further distinguis
