Abstract The 1.85 Ga paleosol at Flin Flon, Manitoba, Canada, was one of the first paleoweathering profiles taken as evidence for a dramatic rise in the oxygen content of the Paleoproterozoic atmosphere. Diagenesis and greenschist-facies metamorphism have modified the abundances of some major elements (e.g., K and Fe) in the Flin Flon paleosol. Inductively coupled plasma-mass spectrometry (ICP-MS) analyses reveal a positive Ce anomaly on both chondrite- and Amisk basalt-normalized REE patterns…

The 1.85 Ga Flin Flon paleosol located in Flin Flon, Manitoba, Canada, is studied with the purpose of determining the timing and geochemical trend of uranium migration. Radiometric minimum ages of
Chromium geochemistry of the ca. 1.85 Ga Flin Flon paleosol
Fractionation of stable Cr isotopes has been measured in Archaean paleosols and marine sedimentary rocks and interpreted to record the terrestrial oxidation of Cr(III) to Cr(VI), providing possible
REE redistributions during granite weathering: Implications for Ce anomaly as a proxy for paleoredox states
Abstract Different responses of Ce to the redox state from those of the other light rare earth elements (LREEs) can be used to understand paleoredox states. To establish the possibility of using the
Pb-Pb isotope composition of the Flin Flon paleosols: Implications for oxidative weathering at ~1.85 Ga
Summary Pb-Pb isotope ratios were measured on 24 drillcore samples of the 1.85 Ga Flin Flon paleosol, adjacent siliciclastic and volcanoclastic sediments as well as volcanics, to determine the

TLDR
The oxidation and retention of iron within the Flin Flon paleosol indicates that PO2 was probably > or = 10(-2) P.A.L. at the time of weathering, which suggests that a significant increase in the ratio of PO2/PCO2 in the atmosphere took place between 2200 and 1800 mybp.

ABSTRACT At the time of deposition, black shales record geochemical information related to the provenance and conditions of deposition for that rock. These initial geochemical conditions are

The authors have used the single-zircon Pb-evaporation technique to determine the age of granitoids in the western Flin Flon domain of the Trans-Hudson orogen in Canada and to constrain the timing of
Evidence in pre-2.2 Ga paleosols for the early evolution of atmospheric oxygen and terrestrial biota
TLDR
All paleosols, regardless of age, retain some characteristics of soils formed under an oxic atmosphere, such as increased Fe3+/Ti ratios from their parental rocks, according to a new approach.
