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

Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

Formation

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

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
