Trachyandesite and Coal

1 Definition
1.1 Definition
Trachyandesite is an extrusive igneous rock.
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

5 Formation
5.1 Formation
Trachyandesite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.
