dc.description.abstractOngoing mapping, chemostratigraphy, geochronology, and stratigraphic analysis of Neoproterozoic successions in the Ogilvie Mountains requires redefinition and correlation of the Fifteenmile Group across the Proterozoic inliers in Yukon. Here we present new stratigraphic logs through the lower Fifteenmile Group in the Coal Creek and Hart River inliers. Based on these data and new observations, we propose redefinition of the lower Fifteenmile Group. A succession dominated by sandstone, mapped as unit PPD1 in the Hart River inlier, is now recognized at the base of the Fifteenmile Group in the Coal Creek inlier. These strata unconformably overlie the Pinguicula Group and transition upward into a distinctive carbonate interval; together, these comprise the informally defined Gibben formation. The shallowing-upward carbonate sequence contains abundant oolitic grainstone and packstone and microbial laminated dolostone. It is capped by a distinct interval of mud-cracked maroon mudstone, siltstone, and fine-grained sandstone that forms the base of what we informally define as the Chandindu formation. The mud-cracked shale transitions upwards into interbedded shale, coarse-grained sandstone, and minor carbonate. The overlying informally defined Reefal assemblage consists of up to 1 km of complexly interbedded carbonate and shale, with variable truncation beneath the major angular unconformity at the base of the Callison Lake Dolostone. The lower Fifteenmile Group (now informally PPD1 through the Chandindu formation) likely correlates with the Hematite Creek Group in the Wernecke Mountains.en_US
