The Mineral Evolution database is currently under development.
The goal of this page is to present localities at which the mineral is found, and estimates of the oldest possible geologic age of the minerals at these localities.

This Mineral list contains entries from this locality, including sub-localities. Minerals in bold are reported by mindat.org as occurring directly at this locality, and do not occur at any children (sublocalities) of this locality.Elements at this locality, including sub-localities: AlBeCCaCeCuFeHKMoNaOPPbSSiUYElements from minerals reported directly at this locality: Structural Groups for minerals in this locality:
The Pb/Pb and Pb/U ages for the sample taken from the Bjertnes Pegmatite were concordant with themselves and were described in the literature as being similar in age to other volcanic rocks of the area.
The Pb/Pb and Pb/U ages for the sample taken from the Bjertnes Pegmatite were concordant with themselves and were described in the literature as being similar in age to other volcanic rocks of the area.
The Pb/Pb and Pb/U ages for the sample taken from the Bjertnes Pegmatite were concordant with themselves and were described in the literature as being similar in age to other volcanic rocks of the area.
The Thorium age is described in the literature as being the least reliable or the most discordant ages and does not constitute a serious objection to the ~950 Ma age given by the other results.
