  • Basalt Wikipedia

    Basalt is an aphanitic fine grained igneous rock that is relatively low in silica and alkali its total content of quartz feldspar and feldspathoid QAPF less than 10% by volume is feldspathoid and less than 20% is quartz with plagioclase making up at least 65% of its feldspar content This places basalt in the basalt/andesite field of the QAPF diagram
