Basalt - definition of basalt by The Free Dictionary
Basalt is an igneous rock that forms from the relatively rapid solidification of basaltic lavas; that is, those magmas that are relatively high in iron and magnesium, and low in silica and aluminum. These features give basalt its dark color and higher relative density when compared to silicate igneous rocks.
