Long-lasting tectonic activities of the Lepontine Dome. New evidence from low-temperature thermochronology

Orogen‐Parallel Migration of Exhumation in the Eastern Aar Massif Revealed by Low‐T Thermochronometry

“…In addition to the 94 new thermochronometric ages, we compiled 595 AFT, (U-Th)/He on apatite (AHe), ZFT, and ZHe ages from previous studies (Berger et al, 2020;Campani et al, 2010;Cederbom et al, 2004;Ciancaleoni, 2005;Elfert et al, 2013;Evans, 2011;Giger, 1991;Glotzbach et al, 2009;2010;Hess, 2003;Hunziker et al, 1992;Hurford, 1986;Janots et al, 2008;Keller et al, 2005;Lihou et al, 1995;Michalski & Soom, 1990;Mock et al, 2020;Price et al, 2018;Rahn, 1994Rahn, , 2001Rahn et al, 1997;Reinecker et al, 2008;Schaer et al, 1975;Spiegel et al, 2000Spiegel et al, , 2001Steiner, 1984;Timar-Geng et al, 2004;Valla et al, 2016;Vernon, van der Beek, Sinclair, Persano, et al, 2009;von Hagke et al, 2012von Hagke et al, , 2014Wagner & Reimer, 1972;Wagner et al, 1977Wagner et al, , 1979Weh, 1998;Weisenberger et al, 2012), by building on an existing compilation by Fox et al (2016). These are the data that are shown on Figures 3-5, with no filtering of potentially unreliable ages applied.…”

“…All data included in the inverse model have been previously published (Berger et al., 2020; Campani et al., 2010; Cederbom et al., 2004; Ciancaleoni, 2005; Elfert et al., 2013; Evans, 2011; Giger, 1991; Glotzbach et al., 2009, 2010; Hess, 2003; Hunziker et al., 1992; Hurford, 1986; Janots et al., 2008; Keller et al., 2005; Lihou et al., 1995; Michalski & Soom, 1990; Mock et al., 2020; Price et al., 2018; Rahn, 1994, 2001; Rahn et al., 1997; Reinecker et al., 2008; Schaer et al., 1975; Spiegel et al., 2000, 2001; Steiner, 1984; Timar‐Geng et al., 2004; Valla et al., 2016; Vernon, van der Beek, Sinclair, Persano, et al., 2009; von Hagke et al., 2012, 2014; Wagner et al., 1977, 1979; Wagner & Reimer, 1972; Weh, 1998; Weisenberger et al., 2012) or are available in Fox et al. (2015) which was the basis of the compilation used in this study.…”

Dating tectonic activity in the Lepontine Dome and Rhone-Simplon Fault regions through hydrothermal monazite-(Ce)

“…70-50 Ma (Kurz et al, 2011;van Gelder et al, 2015). The three areas have in common that exhumation or cooling rates were low during the time of hydrothermal monazite-(Ce) crystallization (e.g., Fügenschuh et al, 2000;Steck et al, 2013) compared to other parts of the Alps from which hydrothermal monazite-(Ce) was dated (Gnos et al, 2015;Bergemann et al, 2017Bergemann et al, , 2019bRicchi et al, 2019).…”
