1.1 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

Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava
