Record #135647:

U-Pb zircon ages from Sørvaranger, Norway, and the western part of the Kola Peninsula, Russia / Oleg A. Levchenkov, and 7 others.

Title: U-Pb zircon ages from Sørvaranger, Norway, and the western part of the Kola Peninsula, Russia / Oleg A. Levchenkov, and 7 others.
Author(s): Levchenkov, Oleg A.
Date: 1995.
Publisher: Trondheim, Norway: Geological Survey of Norway
In: Geology of the Eastern Finnmark - Western Kola Peninsula Region. (1995.),
Abstract: New datings on zircon and titanite from Archaean rocks are given, with oldest 2900 Ma from Hompen gneiss. Several grey gneisses yield ages of 2.8 Ga. Intrusions are dated. No Early Archaean rocks were found at surface. Regional granulite-facies metamorphimism seems to have culminated prior to 2.7 Ga, by which time main crustal elements of northern Baltic Shield were probably assembled, with deformations to follow.
