Variscan cycling of gold into a global coal reservoir ...

This cycling of gold is evidenced by enriched coal and gold palaeoplacers in coal-bearing sequences in numerous basins along the orogen. Provenance data, especially detrital zircon ages of 350 to 300 Ma, help to identify successions that were sourced from gold-rich terrains, and thus can focus the search for anomalously enriched coal.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
