Pg. 14, 18-21. Jellico formation. Applied to 500 or 600 feet of rocks overlying Briceville shale and underlying Scott shale in northern Tennessee coal field. The rocks occupying this position have previously been called Wartburg sandstone, but that name is a misnomer and has been so misapplied that it is discarded. The sandstone at Wartburg occupies stratigraphic position in lower part of Briceville shale, 30 or 40 feet beneath Poplar Creek or Oliver Springs coal. More than three-fourths of the Jellico is shale, but sandstones are more prominent in it than in either underlying Briceville or overlying Scott formation. The Pioneer sandstone is top member of formation and Smith coal (=Blue Gem coal) is basal member. Age is Pennsylvanian.
Named from occurrence of Jellico coal within the formation as its most prominent economic feature; in northern Tennessee coal field, northern TN.
