mapped up to 2 feet wide and can be fairly continuous over long distances. The <br />gneisses are mapped as a series of folds, which are oriented roughly east-west and <br />have been broken and displaced by faults believed to range in age from Precambrian to <br />Tertiary. The two regional fault orientations that have been mapped within the property, <br />trend approximately east west and north-south (Figure 3). <br />I A notable geologic feature near the site is the Golden fault, which runs approximately <br />' north-south and forms the eastern margin of the north-northwest trending hogback <br />immediately east of the quarry property. A mapped reverse fault trending roughly north- <br />south is located within the quarry property and constitutes the boundary between the <br />metamorphosed Precambrian bedrock (to the west) and the Pennsylvanian sedimentary <br />rocks (to the east) (Smith, 1964; Scott, 1972). The quarry property straddles this <br />boundary, with the majority of the processing plant and the entire asphalt plant located <br />' east of the fault (Figure 3). The bedrock material east of the fault is dominantly <br />composed of upturned sandstones and shales of the Fountain Formation (Scott, 1972). <br />West of this fault, the material is typically mapped as migmatitic, quartzo-felspathic <br />gneiss with intrusions of granitic pegmatite veins (Scott, 1972). <br />Within the main pit of the quarry are two approximately east-west trending faults that <br />' have been exposed as the quarry progresses, one is shown on the map (Figure 3). The <br />fault mapped in Jackson Gulch has been informally named the Jackson Gulch fault is <br />' not shown on the map due to the difficulty to map the surficial trace. The area has been <br />extensively modified and fresh exposures have been covered up by backfill material <br />' before measurements could be made. The unnamed fault that is exposed in the east <br />and west walls of the main pit appears to range between 20 and 50 feet wide (Figure 3). <br />' Exposures of this fault were still visible in the northwest corner of the recently excavated <br />sump of the main pit during this field investigation as well as during last years <br />' investigation (2008), with an average dip of 84° measured (Photo 3). This fault was <br />also mapped by Gable as striking 260-270° and dipping 80-85° to the south, and will <br />' continue to be exposed across the main pit floor as the pit deepens (Figure 3). <br /> <br />3. <br />1
