Formation

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.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.
