Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.   
Novaculite forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The formation of Novaculite can be either of chemical or biological origin.
