2. Specific attention was paid to zones which were carbon- <br />. aceous in nature to be certain that they were analyzed independently. <br />3. For lithologies that were greater than ten feet thick, <br />the individual five foot samples which were bagged were compo5ited <br />for analysis. <br />4. In no instance were the samples to be analyzed represent- <br />ative of a thickness greater than thirty feet. <br />All samples were subsequently taken to Natural Resources Lab- <br />oratory, Inc., 1100 Simms Street, Golden, Colorado for chemical <br />analysis. Table S is a breakdown of the overburden analysis <br />intervals for Pit 2. <br />Physical Properties. <br />Certain physical properties of the overburden samples and mine <br />spoil were determined, including compaction and erodability. The <br />results of these as well as descriptions of other properties are <br />• discussed below. <br />Tcv+ttrc <br />The textureal properties of individual lithologic units <br />of the overburden have been determined by a particle size analysis <br />the results of which are found in Table 10. These analyses are <br />presented in terms of percentages of sand, silt, and clay-sized <br />particles in the total sample. Sand-sized particles range in diameter <br />from 2mm to 1/16mm, silt-sized from 1/16mm to 1/256mm, and clay- <br />sized under 1/256mm. <br />Porositv and Permeabili <br />In conjunction with subsurface water determinations, <br />porosity and permeability tests were performed on representative core <br />samples from the original pit. The results of these tests are <br />• <br />-33- <br />
