1 Definition

1.1 Definition

Oolite is a sedimentary rock formed from ooids, spherical grains which are composed of concentric layers of calcite

Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

5 Formation

5.1 Formation

Oolites form when layers of calcite are deposited around a sand grain or fossil piece and are rolled around in calm water, which makes them round.

Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
