Paleozoic <br /> strata have been folded into an overturned syncline because of the movement along the fault <br /> (Olsen, 1983). Most of the faulting and deformation is constrained to the Laramide-time based on <br /> observations of similar faulting in Cretaceous10 bedrock approximately 15 miles to the west; <br /> however, steep dips within Oligocene waterlaid tuff adjacent to the Chester fault indicate that the <br /> fault likely experienced some post-Laramide movement (Nash, 1980; Olson, 1988). This is <br /> plausible given that north-south trending faults approximately 2 miles east of the southern Chester <br /> fault are known to offset Oligocene volcanic at the surface (Olson, 1983; Nash, 1980). <br /> i6AWN 14,000N 36"24' 12.OWN 10,000N <br /> 77 <br /> '^ <br /> P r <br /> � M a <br /> PC <br /> Pbrn y ` <br /> PC <br /> CT _ <br /> p V m u <br /> Pbm <br /> Y L� aC <br /> 6.t .q <br /> C.l.
