General features.--The chief coal-producing centers of the eastern portion of the Russell coal field lie in the district drained by Lewis Creek and its principal tributaries, Flatrock Creek and Laurel Branch. The coalbearing strata belong wholly to the Norton formation. The only stratigraphic section obtained in this basin was measured at location 179 and is given on p. 28. The Raven coal bed is the lowest and the Lower Banner the highest bed of any mining value exposed in the eastern field. Traces of the LTpper Banner and Splash Dam coal beds are found in the western edge of the Lewis Creek basin, but they are negligibly thin. The predominating structural features of the Lewis Creek basin are the Dry Fork anticline in the northern part and a rather sharp synclinal trough with an axis starting near Della and running due north well into the south flank of the Dry Fork anticline. The axis of the anticline passes from Tazewell County on the east to Buchanan County on the west, crossing Lewis Creek just north of Drill. The coal beds under the influence of this structure lie nearly horizontal from Drill north, whereas south of the axis they dip gently, with a gradient that is nearly uniformly that of the major streams. This relationship of coal beds to the anticline accounts for the continuous and extremely circuitous outcrops of the Kennedy and Lower Banner as indicated on tlie map (PI. XXVIII). The rocks of the Lewis Creek basin are sharply cut off on the southwestshow more
