Summary:
Yellow Leaf quartz schist, named in this report, is of unknown thickness, but is composed of at least 500 ft of thin-layered fine-grained siliceous rock, varying in composition and texture from argillite to fine-grained sandstone. Rock has a well-developed schistose structure, resulting from deformative stresses to which region has been subjected, and therefore the lithologic designation quartz schist can be applied to it. Immediately overlies Jemison chert (Oriskany). No fossils have been found, but unit is believed to be of Oriskany or later Devonian age. Formerly included in Talladega slate.
