Intrusive sheets in contact with a seam usually destroy its value, and, when separated from the coal by sandstone and shale, which form the main body of the Coal Measures, their effect is roughly proportional to the thickness of the sheet, and varies inversely with the distance of the sheet from the coal. The high calorific value of some of the Natal coal seams is attributed to this cause.
