Relicts of Paleoproterozoic LIPs in the Belomorian province, eastern Fennoscandian Shield: barcode reconstruction for a deeply eroded collisional orogen

Posted on 09.09.2021 - 09:38
Geological, geochemical, isotopic and geochronological data for Paleoproterozoic mafic intrusions and dykes indicate that distinct magmatic events dated at c. 2.50, 2.45, 2.40, 2.30, 2.23 and 2.12 Ga can be distinguished in the Belomorian Province, Eastern Fennoscandian Shield. The similarity of Paleoproterozoic magmatic barcodes for the Belomorian Province and Karelian Craton in the c. 2.5–2.1 Ga interval suggests a neighbouring position of these crustal segments in an Archean continent. Intensive tectonic and metamorphic reworking of mafic intrusions and dykes in the Belomorian Province during the c. 2.0–1.8 Ga Lapland–Kola orogeny produced differences in mineral assemblages and tectonic position in comparison with the Karelian Craton.
