Basalt Igneous rock Composition Mafic: plagioclase, amphibole, and pyroxene, sometimes feldspathoids, or olivine. Basalt is a mafic extrusive igneous rock formed from the rapid cooling of lava rich in magnesium and iron exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt, and the eruption of basalt lava is observed by ...

01-02-1986· Abstract. A chemical classification of common basalts and andesites is proposed which utilizes CIPW normative plagioclase compositions (100 an/(ab + an) = AN), differing levels of silica saturation (with respect to CIPW qz, hy, ol or ne), and whole rock Al 2 O 3 abundances and K 2 O/Na 2 O ratios (weight per cent). Extrusives belonging to the basalt-andesite spectrum are divided into ...
