Alps to Apennines zircon roller coaster along the Adria microplate margin
Jacobs, Joachim; Paoli, Gabriele; Rocchi, Sergio; Ksienzyk, Anna Katharina; Sirevaag, Hallgeir; Elburg, Marlina (Peer reviewed; Journal article, 2018-02-09)We have traced the particle path of high-pressure metasedimentary rocks on Elba Island, Northern Apennines, with the help of a U-Pb-Hf detrital zircon study. One quarter of the analysed zircons are surprisingly young, ... -

Deep Crustal Flow Within Postorogenic Metamorphic Core Complexes: Insights From the Southern Western Gneiss Region of Norway
Wiest, Johannes; Osmundsen, Per Terje; Jacobs, Joachim; Fossen, Haakon (Peer reviewed; Journal article, 2019)Viscous crustal flow can exhume once deeply buried rocks in postorogenic metamorphic core complexes (MCCs). While migmatite domes record the flow dynamics of anatectic crust, the mechanics and kinematics of solid‐state ... -
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 ... -
Shear zone evolution during core complex exhumation – Implications for continental detachments
Wiest, Johannes; Fossen, Haakon; Jacobs, Joachim (Journal article; Peer reviewed, 2020)The formation of low-angle detachments involves exhumation of previously ductile material and fault zone weakening. To better understand this relationship, we studied a deeply eroded metamorphic core complex, which formed ... -
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 ...
