Grenville-age continental arc magmatism and crustal evolution in central Dronning Maud Land (East Antarctica): Zircon geochronological and Hf-O isotopic evidence
Wang, Cheng-Cheng; Jacobs, Joachim; Elburg, Marlina A.; Läufer, Andreas; Thomas, Robert J.; Elvevold, Synnøve (Peer reviewed; Journal article, 2020)This study focusses on the Grenville-age Maud Belt in Dronning Maud Land (DML), East Antarctica, which was located at the margin of the Proto-Kalahari Craton during the assembly of Rodinia. We present new U–Pb zircon ages ... -
Late Neoproterozoic–Cambrian magmatism in Dronning Maud Land (East Antarctica): U–Pb zircon geochronology, isotope geochemistry and implications for Gondwana assembly
Wang, Cheng-Cheng; Jacobs, Joachim; Elburg, Marlina; Läufer, Andreas; Elvevold, Synnøve (Journal article; Peer reviewed, 2020)Dronning Maud Land (DML) is a key area for the better understanding of the geotectonic history and amalgamation processes of the southern part of Gondwana. Here, we present comprehensive new zircon U–Pb–Hf–O, whole-rock ... -
Protracted late Neoproterozic – early Palaeozoic deformation and cooling history of Sør Rondane, East Antarctica, from 40Ar/39Ar and U–Pb geochronology
Ruppel, Antonia S.; Jacobs, Joachim; Läufer, Andreas; Ratschbacher, Lothar (Journal article; Peer reviewed, 2020)40Ar/39Ar and U–Pb data from five structural domains constrain the late Neoproterozoic – early Palaeozoic tectonothermal history of the eastern part of the East African–Antarctic Orogen in Sør Rondane. A total of 27 new ... -
Tectono-thermal evolution and morphodynamics of the central dronning maud land mountains, east antarctica, based on new thermochronological data
Sirevaag, Hallgeir; Ksienzyk, Anna Katharina; Jacobs, Joachim; Dunkl, István; Läufer, Andreas (Peer reviewed; Journal article, 2018-10-26)The lack of preserved Mesozoic–Cenozoic sediments and structures in central Dronning Maud Land has so far limited our understanding of the post-Pan-African evolution of this important part of East Antarctica. In order to ...
