Permian magmatism and metamorphism in the Dent Blanche nappe: constraints from field observations and geochronology

Manzotti, Paola ; Rubatto, Daniela ; Zucali, Michele ; El Korh, Afifé ; Cenki-Tok, Bénédicte ; Ballèvre, Michel ; Engi, Martin

In the Dent Blanche Tectonic System, the Mont Morion biotite-bearing granite is a km- scale intrusion preserved in a low-strain volume. Zircon saturation thermometry suggests that it crystallised from a melt that reached about 800 °C. U–Pb zircon and allanite geochronology indicates crystallization of the magma in the Permian (290 ± 3 Ma; 280 ± 8 Ma, respectively). Migmatitic...

The north-subducting Rheic Ocean during the Devonian: consequences for the Rhenohercynian ore sites

Raumer, Jürgen F. von ; Nesbor, Heinz-Dieter ; Stampfli, Gérard M.

In: International Journal of Earth Sciences, 2017, vol. 106, no. 7, p. 2279–2296

Base metal mining in the Rhenohercynian Zone has a long history. Middle-Upper Devonian to Lower Carboniferous sediment-hosted massive sulfide deposits (SHMS), volcanic-hosted massive sulfide deposits (VHMS) and Lahn-Dill-type iron, and base metal ores occur at several sites in the Rhenohercynian Zone that stretches from the South Portuguese Zone, through the Lizard area, the Rhenish Massif...

Neurovascular EGFL7 regulates adult neurogenesis in the subventricular zone and thereby affects olfactory perception

Bicker, Frank ; Vasic, Verica ; Horta, Guilherme ; Ortega, Felipe ; Nolte, Hendrik ; Kavyanifar, Atria ; Keller, Stefanie ; Stankovic, Nevenka Dudvarski ; Harter, Patrick N. ; Benedito, Rui ; Lutz, Beat ; Baüerle, Tobias ; Hartwig, Jens ; Baumgart, Jan ; Krüger, Marcus ; Radyushkin, Konstantin ; Alberi, Lavinia ; Berninger, Benedikt ; Schmidt, Mirko H.H.

Adult neural stem cells reside in a specialized niche in the subventricular zone (SVZ). Throughout life they give rise to adult-born neurons in the olfactory bulb (OB), thus contributing to neural plasticity and pattern discrimination. Here, we show that the neurovascular protein EGFL7 is secreted by endothelial cells and neural stem cells (NSCs) of the SVZ to shape the vascular stem-cell...
