• <br />9 <br />2. FASTSI~ QJAL M]I~ <br />The property is located in the Harvey Gap area near the Carbon- <br />dale mal field (Figure 1). The Harvey Gap area contains six mine- <br />able coal seams of Cretaceous age. The oldest rocks belong to the <br />Mancos shale formation aryl are oompo:~~d of marine shales of gray <br />Dolor with beds of sandstones, particularly in the upper part of the <br />strata (Figure 2). Mancos shales are overlie the Iles formation <br />which belongs to the Mesa Verde group. The Iles formation is cx.,n- <br />posed fran interbedded sandstones, sandy and carbonaoeaLS shales and <br />coals. Arother massive sandstone bed occurs some 400 feet below the <br />top of the formation, as it is described by Gardner, 1974. <br />• The Williams Fork formation which lies on the Iles formation is <br />about 3,300 feet thick in the Harvey Gap area and is also composed <br />from massive sandstones, shales and coals (Table t). <br />The dip of the beds in the Harvey Gap area is about 56 <br />degrees and the strike of the rocks is about N72 W iFigure 3). <br />Minor faults were reported in the Rifle Gap area. As has been men <br />boned, six mineable coal beds are reported in the Harvey Gap area. <br />The E seam which is currently under development is about 20 feet <br />thick. The Wheeler seam is reportedly located in the overhanging <br />strata and has an expected thickness of 95 feet. However, th? <br />exploratory drilling performed in 1983 up to the distance of 240 <br />feet did not reach the seam. In the footwall, the Harvey Gap seam is <br />• believed to be located at a distance of 1,000 feet below the J•; x~ni. <br />
