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.

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
