Publisher-reported update

2026-08-26

Precambrian-Cambrian boundary strata of the Wernecke Mountains east-central Yukon comprise a succession of alternating carbonate and siliciclastic units. To date only minor showings of economic mineral deposits have been described from carbonate strata. Most of these deposits are hosted by an unnamed Upper Proterozoic dolostone unit, or by Lower Cambrian carbonates of the Sekwi Formation. Lithostratigraphic, biostratigraphic and sedimentological studies of the entire Precambrian-Cambrian boundary succession were carried out in order to determine the depositional history and mineral potential.
