West Elk one <br />. Charleston, WV. Between 1992 and 2000, Commercial Testing and Engineering Laboratories of <br />Denver, Colorado conducted the laboratory analysis. Prior to 1992, several other laboratories <br />performed laboratory analyses. <br />Strati¢raphy <br />The general geology of this portion of the southeast Picance Basin consists of gently north- <br />northeast dipping beds of sandstone, shale, and coal of Upper Cretaceous and early Tertiary age. <br />The main coal beds are found in the Upper Cretaceous Mesaverde Group which is overlain by <br />the early Tertiary Ohio Creek Conglomerate and underlain by the Upper Cretaceous Mancos <br />Shale. Locally, the Mesaverde Formation is about 2,500 feet thick. Figure 4, shows a <br />generalized stratigraphic column. Map 9 shows the geology of the permit azea, the coal outcrop <br />line and strike and dip for the F, E, and B Seams. It has been modified after C. R. Dunnxd's 1989 <br />geologic map and incorporates more recent geologic mapping data (Intraseazch, Inc. 1993 and <br />1994). Although Dunrud placed the top of the Upper Coal Member above the F-Seam, MCC <br />uses the top of the F Seam as the top of the member. <br />Stratigraphic cross-sections between drill holes show the subsurface geology through the permit <br />azea. The locations of these cross-sections aze shown on Map 10. Figure SA (Cross-Secfion A-A') <br />crosses the lease area from north to south. Figure SB (Cross Section B-B') crosses from the Fee <br />land in the north through the Fee land in the south (including Federal leases C-56447 and C- <br />1362. Figure SC (Cross-Section C-C') crosses lease C-56447 from the north to C-1362 to the <br />south in the eastern area of the leases. Figure SD (Cross-Section D-D') crosses west to east <br />over C-0117192 through C-044569 to C-56447. Figure SE (Cross-Section E-E') runs west to <br />east on the northern edge of the South of Divide permit revision area. Figure 5F (Cross- <br />Section F-F') crosses the center of South of Divide permit revision area from west to east. <br />Figures SA through 5 F are situated in map pockets attached to the text. <br />Chazacteristic lithologic logs have been included for core holes SOM 6, SOM 38, SOM 42, JMB <br />11, SOW-3, RAV-2, RAV-4B, and RAV-7 (Exhibit 12). <br />Mancos Shale <br />The Mancos Shale, the oldest formation exposed in the Paonia area, consists of a sequence of <br />dark gray to buff marine shale approximately 2,000 to 3,000 feet thick. <br />Mesaverde Formation <br />The Mesaverde Group conformably overlies the Mancos Shale and is comprised in ascending <br />order of these five stratigraphic units; the basal Rollins Sandstone Member, the Lower Coal <br />Member, the Upper Coal Member, the Barren Member, and the Ohio Creek Member. <br />.. <br />2.04-13 Revised November 1004 PRt 0 <br />
