Economic importance - that is, between Morrow Gap and Sparks Gap - there are four important beds, known, respectively, in their order from top to bottom, as the Hickory Nut, Ida, Big, and Irondale seams. The Hickory Nut seam is the least important of the four and has received little attention. It comprises 3 to 5 feet of sandy ore or ferruginous sandstone, characterized by abundant fossils of the brachiopod Pentamerus oblongus, which, on account of looking like a hickory nut in its hull, has given the bed the name.
