What is the age of coal?

To find the answer, we need to go back in time to a period when the rocks were forming. These rocks date back to a time between roughly 360 – 290 million years ago, to a period known in popular culture as the Age of Coal. To scientists, it is the Carboniferous Period, the ‘golden age of forests.

How old are coal deposits?

Which is the youngest coal?

Is Coal still being formed?

The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.

Will we ever run out of oil?

Globally, we currently consume the equivalent of over 11 billion tonnes of oil from fossil fuels every year. Crude oil reserves are vanishing at a rate of more than 4 billion tonnes a year – so if we carry on as we are, our known oil deposits could run out in just over 53 years.
