WhatsApp: +86 18203695377Volcanic ash fell on top of huge floating log mats. When those log mats were buried inbetween the heated sedimentary layers deposited by the Flood, coal and oil were formed in a short amount of time. Laboratory research in the past few decades has shown that coal and oil may be formed quickly.
WhatsApp: +86 18203695377It is used as fuel.
