What is lava rock composed of? Lava is made up of crystals, volcanic glass, and bubbles (volcanic gases). As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases. When lava erupts it is made up of a slush of crystals, liquid, and bubbles.
Does lava rock have minerals? Because of their chemical composition, lava rocks classify as basalts. They are not only rich in magnesium and iron but also calcium.
