Description :
5I. Polymict conglomerate at the interface between the Ps1 quartzite and the first Ps3 basalt infold west of geochronology locality 40 (Fig. 6). The normally intervening Ps2 fine siliciclastic unit is not present at this locality. The grey-green impure quartzarenite matrix is typical of the upper Ps1 quartzite in the Whitehills Lake area, whereas the common scoria clasts (s) of this outcrop are atypical. Additional clasts not shown include vein quartz and Pukiq Formation rhyolite.
