GEOLOGY


Geo_Coalisland_Spade_Mill.jpg In Tyrone  is the only field which offers much scope for the prospector, for it is very probable that here the Coal Measures dip under the Triassic sandstones to the east. The coal is of the bituminous type and occurs in thick seams. One of these, the Annagher seam, is 9 ft. thick. Deposits of fireclay and coal are being worked in the vicinity of Coal Island. Lignite is found at Sandy Bay on the eastern shores of Lough Neagh.
