general term for dark-colored mafic igneous rock, usually extrusive, containing less than 52 weight percent silica
Basalt is a type of black rock that is produced by volcanoes. a type of dark green-black rock (basaltes, from basanos , from bhnw). Dark igneous rock that is low in silica content and comparatively rich in iron and magnesium. Some basalts are glassy (have no visible crystals), and many are very fine-grained and compact. Basaltic lavas may be spongy or pumice-like. Olivine and augite are the most common minerals in basalts; plagioclase is also present. Basalts may be broadly classified into two main groups. Calc-alkali basalts predominate among the lavas of mountain belts; the active volcanoes of Mauna Loa and Kilauea in Hawaii erupt calc-alkali lavas. Alkali basalts predominate among the lavas of the ocean basins and are also common in mountain belts
A dark, heavy, fine-grained, extrusive igneous rock consisting almost equally of plagioclase feldspars and ferro-magnesium minerals; most common variety of volcanic rock

the commonest type of solidified lava; a dense dark gray fine-grained igneous rock composed chiefly of calcium-rich plagioclase feldspar and pyroxene

    [ b&-'solt, 'bA-" ] (noun.) 1601. Late Latin basaltes, a misspelling of Latin basanites, from Ancient Greek βασανίτης (basanitēs), from βάσανος (basanos, “touchstone”), from Egyptian bauhan 'slate'.
