Stratigraphy summary for southeast Yukon (NTS 95D/8 and 95C/5)

Sedimentary strata located within NTS map sheets 95C/5 and 95D/8, southeast Yukon, have a combined thickness ranging between 5000 and 15000 m and depositional ages ranging from Proterozoic to Paleocene. They can be grouped into eight successions with formations within each succession indicating either similar depositional environments or a horizontal or vertical lithological facies zonation. Early to middle Paleozoic successions are best exposed; Proterozoic, Late Paleozoic, Mesozoic and Cenozoic successions are only locally exposed. Many of the successions are bounded by unconformities; some also contain internal depositional hiatuses. The deposition and preservation of the successions reflect the regional tectonic framework of the Canadian Cordillera from Neoproterozoic to present.
