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, ... -

Arctic sediment routing during the Triassic: sinking the Arctic Atlantis
Gilmullina, Albina; Klausen, Tore Grane; Doré, Anthony George; Sirevaag, Hallgeir; Suslova, Anna; Eide, Christian Haug (Journal article; Peer reviewed, 2022)Opening of the Arctic Ocean has been the subject of much debate, and the placement of terranes in the Early Mesozoic remains a crucial part of this important discussion. Several continental terranes complicate the ... -
Nature and origin of the cover sequence of the Tuscan basement on Elba Island: evidence from detrital zircon dating
Sirevaag, Hallgeir (Master thesis, 2013)Elba Island represents the westernmost part of the northern Apennines and has, for the last decades, been a subject to comprehensive geological studies. Due to west-directed subduction of the Adriatic microplate below ... -
Substantial spatial variation in glacial erosion rates in the Dronning Maud Land Mountains, East Antarctica
Sirevaag, Hallgeir; Jacobs, Joachim; Ksienzyk, Anna Katharina (Journal article; Peer reviewed, 2021)The coast-parallel Dronning Maud Land (DML) mountains represent a key nucleation site for the protracted glaciation of Antarctica. Their evolution is therefore of special interest for understanding the formation and ... -
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 ...
