• associated strata ranges from 14 to 25 percent, or 8 to 14 degrees, <br />to the west. <br />Ae shown on lisp 2, Mine No. 3 Geology, no serious faulting <br />occurs eacept within a 200 foot wide zone in the proposed permit <br />area. This zone is dovndip from and outside of the surface mine <br />area. Faulting within the zone is eacluaively of the normal or <br />gravity kind and occurs as horst-and-graben or step types. <br />Displacement acrasa the fault zone, measured in terms of <br />etratigraphic throw, ranges from 60 to 100 feet. It is believed <br />that the faulting in the proposed permit area occurred subsequent to <br />• the initial folding of the poet-Cretaceous time during the Laramide <br />Orogeny. The strike of the faulting is northwest-southeast in the <br />proposed permit area. <br />As required by this Rule, detailed structural characteristics, <br />including structure contours of the Wedge Seam in the proposed <br />permit area, are shown on Map 2, Hine No. 3 Geology, and Map 3, !fine <br />No. 3 Geologic Cross-Sections A, B and C. These maps have been <br />prepared in accordance with Rule 2.10. <br />The outcrop patterns and configurations of overburden <br />thicknesses are determined by a combination of topography and <br />geologic structure. At the surface mine, the Wedge coal seam is <br />• situated on a sloping hogback called a "dip-slope". A dip-slope is <br />a landform where the general topographic surface dips in the same <br />2.04-24 <br />
