Remarks on the Longford Coal Basin

The Norwich coal seams near Longford, opened out by Mr. Mason and others, have only been discovered recently, although the existence of the Mesozoic Coal Measure Sandstones in the immediate neighbourhood-notably at Hadspen-had long been known.
The exact extent of this basin of coal has not yet been determined.
Rocks of Mesozoic and Upper Palmozoic age are to be found everywhere bordering this ancient Tertiary Lake Basin, and even near its centre.
It is evident that the coal measures have been subject to violent pressure laterally since their deposition.
