Martin Marietta Materials <br />Spec -Agg 2015 Annual Report <br />A mapped reverse fault trending roughly north -south is located within the quarry property and constitutes <br />the boundary between the metamorphosed Precambrian bedrock to the west and the Pennsylvanian <br />sedimentary rocks to the east (Smith, 1964; Scott, 1972). The quarry property straddles this boundary, <br />with the majority of the processing plant and the entire asphalt plant located east of the fault (Figure 3). <br />The bedrock material east of the fault is dominantly composed of upturned sandstones and shales of the <br />Fountain Formation (Scott, 1972). West of this fault, the material is mapped as migmatitic quartzo- <br />felspathic gneiss with intrusions of granitic pegmatite veins (Scott, 1972). <br />Two other approximately north -south trending faults exposed in the northern quarry walls, as shown on <br />Figure 3 and discussed in previous 2013 report. The north -south trending faults at the mine roughly <br />parallel the Golden Fault, which is a major fault that forms the north - northwest trending hogback <br />immediately east of the quarry property. <br />February 25, 2015 Page 4 Lachel & Associates, Inc. <br />Project 14364006 00 02015 All Rights Reserved <br />
