Definition

Mugearite is a type of oligoclase bearing basalt, also comprising of olivine, apatite, and opaque oxides

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

Formation

Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

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.
