Supracrustal rock



Supracrustal rocks are rocks that were deposited on the existing basement rocks of the crust, hence the name. They may be further metamorphosed from both sedimentary and volcanic rocks.

Additional recommended knowledge

The Isua greenstone belt contains the oldest, well preserved, supracrustals, dated at 3.8-3.7 Ga.
