First record of carbonates with spherulites and cone-in-cone structures from the Precambrian of Arctic Norway, and their palaeoenvironmental significance
Meinhold, Guido; Jensen, Sören; Høyberget, Magne; Arslan, Arzu; Ebbestad, Jan Ove R.; Högström, Anette; Palacios, Teodoro; Agic, Heda; Taylor, Wendy L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-10)We report for the first time carbonates from the upper Ediacaran sedimentary succession of Finnmark, Arctic Norway. Carbonates occur as calcareous siliciclastic beds, lenses, and concretions, some with calcite spherulites and cone-in-cone (CIC) calcite, in a mudrock to fine-grained sandstone succession from approximately 3 m to 26 m above the base of the 2nd cycle of the Manndrapselva Member of the ... -
U-Pb dating of calcite in ancient carbonates for age estimates of syn-to post-depositional processes: A case study from the upper Ediacaran strata of Finnmark, Arctic Norway
Meinhold, Guido; Roberts, Nick M.W.; Arslan, Arzu; Jensen, Sören; Ebbestad, Jan Ove R.; Högström, Anette; Høyberget, Magne; Agić, Heda; Palacios, Teodoro; Taylor, Wendy L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-10)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 ... -
