1 Definition
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
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

1.3 Etymology
From its mineral and compound content and its relation with Basalt and Andesite rock
From the Old English term col, which has meant mineral of fossilized carbon since the 13th century

5 Formation
5.1 Formation
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
