5 Formation

5.1 Formation

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.

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
