Coal measure
From Wikipedia, the free encyclopedia
Coal Measures (stratigraphic unit) is the stratigraphic term used in Europe (especially in Great Britain) for the Upper 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 ranging in thickness from a metre or so to a few thousand metres, that consists of mainly clastic rocks (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. For example the Permian coal measures of Australia and the late Cretaceous and early Tertiary coal measures found in New Zealand.
