WebBaked sedimentary xenoliths in clinker (Wasatch Formation, Lower Eocene; coal fire metamorphism at 19 ka, Late Pleistocene; large block at Interstate 90 west-bound hilltop rest area, east of Buffalo, Powder River Basin, Wyoming, USA) 1.jpg WebClinker is a scarce, odd rock. It occurs adjacent to former coal bed horizons. Coal is combustible - that’s why coal is used as an energy source in human society. Coal beds can ignite accidentally or naturally. Accidental coal bed ignition often leads to environmental disaster areas (for example, Centralia, Pennsylvania, USA). cleaner for waterproof jackets

WebJul 4, 2015 · “Clinker” is the term for thermal metamorphic rocks (combustion metamorphic rocks) that have been significantly altered by the heat of burning coal beds. The appearance and color of clinker varies significantly. Scoriaceous to semivitreous clinker is called buchite, which formed by partial fusion/melting.
