5.1 Formation

Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

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.
