accumulation of organic matter, compression into peat, compression into coal
Plant and animal remains sandstone and shale from my grandad(a miner deputy manager) mainly trees very rare for animals, always lowerlifeforms
Rotting vegetation is overlaid by more rotting vegetation or other material. This is compressed by the mass above and form peat. Compression of the peat continues and form lignite (brown coal) Compression continues on the lignite to form coal (clack shiny rock) Compression may continue to form anthracite , the hardest form of coal . NB with each compression watert/moisture is expelled, so coal and anthracite are very dry.
Coals are formed by plants, after millions of years they become coal.

Coal
coal. coal is formed.
Coals are formed by plants, after millions of years they become coal.
Coal was formed when massive amounts of vegetation died and fell into the swamps they grew in. This happened in the Carboniferous Period. Huge mats of waterlogged plant material were formed that resisted decay because there was very little oxygen there. Over millions of years, as the climatic and geologic conditions changed, these plant sediments were covered and compacted by other sediments, resulting in their conversion to coal.

Diamonds are not formed in coal: each is an allotrope of carbon and are formed by Mother Nature under entirely different circumstances.
metamorphism
Coal is formed from plants, which turned into peat, then lignite, then coal.
