Add ⊕

Definition

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

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

History

Formation

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

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