Extract

The Millstone Grit and Coal Measure rocks of West Yorkshire include a series of sedimentary ironstones characterized by the spherulitic habit of the siderite. These rocks have been examined in detail in Airedale and Calderdale, and in brief visits to East Lancashire and South-West Yorkshire the author has recognized a similar development of ironstones, and so believes that the substance of this paper may be generally applicable to the whole of the central and southern Pennine region.
