Geology, Mount Joyal, Yukon / [Author: L.S. Lane]. : M183-1/73-2013E-PDF
"This map is dominated by a broad anticline-syncline fold pair. The Tuttle anticline and North and South Tuttle synclines are developed in shale and coarse clastic rocks of the uppermost Imperial and overlying Tuttle formations. Biostratigraphic ages vary from Late Frasnian (Late Devonian) to Viséan (Early Carboniferous). Along the east margin of the map area, the Deception fault juxtaposes the middle, sandy part of the Imperial Formation, of Frasnian to early Famennian age, against the Tuttle Formation. A distinct thermal maturity discontinuity occurs across the fault, with rocks to the east having vitrinite reflectances (Ro) of 1.16–1.3% whereas those to the west have Ro = 0.7–0.8%. Seismic reflection data suggest that the fault has a moderate eastward dip. Taken together, these data indicate that the Deception Fault is a substantial thrust fault. Sandstone and conglomerate of the Tuttle Formation display rapid lateral variations in thickness and facies. This is reflected in the delineation of four mappable lithofacies with no specific stratigraphic order. Although poor exposure precludes a definitive explanation, a channellized depositional system is inferred"--Abstract.
