1.1 Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
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
1.2 History
1.2.1 Origin

1.3 Etymology
From late Middle English (denoting slag from molten metal), from Greek skōria refuse, from skōr dung
From its mineral and compound content and its relation with Basalt and Andesite rock

5.1 Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
