Encyclopedia > Coal Measures

A coal measure (stratigraphic unit) is the name given to any rock sequence that occurs in the upper part of the Carboniferous System in Europe. It is equivalent to the Pennsylvanian of North America. These rocks are typically coal-bearing.

The term coal measure is also used to describe a succession of sedimentary rocks comprising of claystones, shales, siltstones, sandstones, conglomerates, and limestones that are interstratified with beds of coal. Such succession occur worldwide and may not necessarily be Carboniferous in age (such as the Permian coal measures of Australia and the late Cretaceous and early Tertiary coal measures found in New Zealand).

Coal then meant the carbonaceous residue obtained in the destructive distillation of wood, or what is known as charcoal, and the name collier was applied indifferently to both coal-miners and charcoal-burners.
The Coal Measures which form part of the Palaeozoic or oldest of the three great geological divisions are mainly confined to the countries north of the equator.
The uppermost portion of the Coal Measures consists of red sandstone so closely resembling that of the Permian group, which are next in geological sequence, that it is often difficult to decide upon the true line of demarcation between the two formations.
