Book Description
Excerpt from Concentration Experiments With the Siliceous Red Hematite of the Birmingham District, Alabama The-ores are bedded in the Clinton or Rockwood formation of Silurian age, which outcrops along Red Mountain, and gives the mountain its name. The beds dip away from the valley at angles ranging from 15° to but averaging less than One or more ore beds of greater or less importance are everywhere present in the Rockwood formation, and within that part of Red Mountain of greatest. 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. The bed lies about 12 to 20 feet above the Ida seam and reaches its greatest thickness between Birmingham and Bessemer. The other three seams are described on subsequent pages in connection with the results of the concentration experiments.
