Coal Measures
The Coal Measures (stratigraphic unit) is the name given to the sequence of rocks which 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 measures is also used to describe a succession of sedimentary rocks comprising of claystones, shales, siltstones, sandstones, conglomerates, and limestones which 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).
