New Paleomagnetic Data from Precisely Dated Paleoproterozoic-Neoarchean Dikes in NE Fennoscandia, the Kola Peninsula
Geophysical Research Abstracts Vol. 21, EGU2019-3423, 2019 EGU General Assembly 2019 © Author(s) 2019. CC Attribution 4.0 license. New paleomagnetic data from precisely dated Paleoproterozoic-Neoarchean dikes in NE Fennoscandia, the Kola Peninsula Roman Veselovskiy (1,2), Alexander Samsonov (3), and Alexandra Stepanova (4) (1) Schmidt Institute of Physics of the Earth of the Russian Academy of Sciences, Geological, Moscow, Russian Federation ([email protected]), (2) Lomonosov Moscow State University, Faculty of Geology, (3) Institute of Geology of Ore Deposits Petrography Mineralogy and Geochemistry, Russian Academy of Sciences, (4) Institute of Geology, Karelian Research Centre RAS The validity and reliability of paleocontinental reconstructions depend on using multiple methods, but among these approaches the paleomagnetic method is particularly important. However, the potential of paleomagnetism for the Early Precambrian rocks is often dramatically restricted, primarily due to the partial or complete loss of the primary magnetic record during the rocks’ life, as well as because of difficulties with dating the characteristic magnetization. The Fennoscandian Shield is the best-exposed and well-studied crustal segment of the East European craton. The north-eastern part of the shield is composed of Archean crust, penetrated by Paleoproterozoic and Neoarchean mafic intrusions, mostly dikes. The Murmansk craton is a narrow (60-70 km in width) segment of the Archean crust traced along the Barents Sea coast of the Kola Peninsula for 600 km from Sredniy Peninsula to the east. At least five episodes of mafic magmatism of age 2.68, 2.50, 1.98, 1.86 and 0.38 Ga are distinguished in the Murmansk craton according to U-Pb baddeleyite and zircon dating results (Stepanova et al., 2018). -
Sequence Stratigraphic Development of the Neoarchean Transvaal Carbonate Platform, Kaapvaal Craton, South Africa Dawn Y
DAWN Y. SUMNER AND NICOLAS J. BEUKES 11 Sequence Stratigraphic Development of the Neoarchean Transvaal carbonate platform, Kaapvaal Craton, South Africa Dawn Y. Sumner Department of Geology, University of California 1 Shields Ave, Davis, CA 95616 USA e-mail: [email protected] Nicolas J. Beukes Department of Geology, University of Johannesburg P.O. Box 524, Auckland Park, 2000 South Africa e-mail: [email protected] © 2006 March Geological Society of South Africa ABSTRACT The ~2.67 to ~2.46 Ga lower Transvaal Supergroup, South Africa, consists of a mixed siliciclastic-carbonate ramp that grades upward into an extensive carbonate platform, overlain by deep subtidal banded iron-formation. It is composed of 14 third-order sequences that develop from a mixed siliciclastic-carbonate ramp to a steepened margin followed by a rimmed margin that separated lagoonal environments from the open ocean. Drowning of the platform coincided with deposition of banded iron-formation across the Kaapvaal Craton. The geometry and stacking of these sequences are consistent with more recent patterns of carbonate accumulation, demonstrating that Neoarchean carbonate accumulation responded to subsidence, sea level change, and carbonate production similarly to Proterozoic and Phanerozoic platforms. The similarity of carbonate platform geometry through time, even with significant changes in dominant biota, demonstrates that rimmed margins are localized primarily by physiochemical conditions rather than growth dynamics of specific organisms. Stratigraphic patterns during deposition of the Schmidtsdrift and Campbellrand-Malmani subgroups are most consistent with variable thinning of the Kaapvaal Craton during extrusion of the ~2.7 Ga Ventersdorp lavas. Although depositional patterns are consistent with rifting of the western margin of the Kaapvaal Craton during this time, a rift-to-drift transition is not required to explain subsidence. -

Especially convincing is evidence, presented by DAMASKE & OAKEY (2006), that at least one basic dyke of Neoproterozoic age extends across Smith Sound from Inglefield Land to inshore eastern Ellesmere Island without any recognizable strike slip offset. INTRODUCTION These results confirm that no major sinistral fault exists in southern Nares Strait. It is apparent to both earth scientists and the general public To account for the absence of a Wegener Fault in most parts of Nares Strait, that the shape of both coastlines and continental margins of the present paper would locate the late Paleocene-Eocene Greenland plate boundary on an interconnected system of faults that are 1) traced through western Greenland and eastern Arctic Canada provide for a Jones Sound in the south, 2) lie between the Eurekan Orogen and the Precam- satisfactory restoration of the opposing lands. -
