... for the fifth, all samples previously correlated to the Sangamonian Stage (80–130 ka) Missinaibi Formation. We interpret the younger TL dates as being within 20–40% of the true deposition ages, but interpret the oldest TL date as an overestimate because of ineffective zeroing of the light-sensitive TL...

...-Barlow varved clays. The fossil plants, chiefly mosses, represent an environment that is common in the region today, and are radiocarbon dated (GSC-2148) as older than 37000 years.

..., ~1.1 million ounces of gold were produced from a number of these veins hosted by shear zones that overprint 2720.8 ± 1.4 Ma biotite tonalite of the Missinaibi Lake batholith. Because of their laminated nature and association with shear zones, the veins were interpreted as syn-orogenic fault-fill veins...

... ). To the east in Ontario, all nonglacial sediments were similarly lumped into the Missinaibi Formation ( Terasmae and Hughes 1960 ; Skinner 1973 ).

... ), therefore placing the Rocksand Till in MIS 6. This alternative framework presented in Thorleifson et al.
