Elizabeth Turner - Neoproterozoic strata, NE Yukon
Stratigraphy, correlation and origin of early Neoproterozoic strata
in northeastern Yukon
Elizabeth Turner and Dr. Darrel Long, (Ontario); Dr. Derek Thorkelson, Simon Fraser University (British Columbia)
Elizabeth Turner and Darrel Long will be joining Derek Thorkelson in
NTS 106C (Nadaleen River) to examine the sedimentology and
stratigraphy of units D, E and F of the former Penguicula Group.
These strata are considered to be stratigraphically equivalent to the
Mackenzie Mountains Supergroup which Long and Turner have examined in
detail in the NWT: they hope to be able to trace second and third
order cyclicity from the type area of the Mackenzie Mountains
Supergroup to the Wernecke Mountains exposures. One distinct outcome
of work on the NWT side of the border was the identification of a
series of sub-basins which extend outwards from the craton and are
separated by transfer faults which appear to have influenced later
migration of ore-bearing fluids. One of the proposed transfer faults
appears to strike directly across the Wernecke Mountains in the
vicinity of exposures in 106C/11 and 14.
