Summary:

Name Wayne formation proposed by H.D. Miser because the rocks to which it is applied are widely exposed and typically developed in Wayne Co., western TN. Consists of five members (ascending): Osgood earthy limestone member (10 to 17 ft thick); Laurel limestone member (19 to 32 ft thick); Waldron clay member (2.5 to 5 ft thick); Lego limestone member (25 to 36 ft thick); and Dixon earthy limestone member (10 to 45 ft thick). Underlies Brownsport formation and overlies Brassfield limestone. Age is Silurian (Niagaran).

Summary:

Unit is used as a formation rather than a group in this report, following the original definition. The Maddox limestone of Foerste (1903) is reinstated and assigned as basal member to the Wayne Formation, replacing the Osgood and Laurel. As revised here, the Wayne Formation is subdivided into (ascending) Maddox, Waldron, Lego, and Dixon Members. Overlies the Brassfield Formation and underlies the Brownsport Formation. Age is Silurian (latest Llandoverian to early Ludlovian).

Summary:

Wayne Group used in AL. Formations within the group are not discussed. Unit is described as red, gray and green silty, argillaceous limestone; red and green shale; and grayish-green nonporous crystalline limestone containing a few scattered pink calcite crystals. Recognizable in the surface and subsurface in the interior Low Plateaus of northern AL. Thickness ranges from 0 to 144 ft. Age is Early and Late Silurian (Ontarian-Lockportian).
