Results of in situ U–Pb dating of calcite spherulites, cone-in-cone (CIC) calcite and calcite fibres
from a calcareous concretion of the upper Ediacaran of Finnmark, Arctic Norway, are reported.
Calcite spherulites from the innermost layers of the concretion yielded a lower intercept age of
563 ± 70 Ma, which, although imprecise, is within uncertainty of the age of sedimentation based
on fossil ...
