Discovery of Ordovician–Silurian metamorphic monazite in garnet metapelites of the Alpine External Aiguilles Rouges Massif
Swiss Journal of Geosciences - Tập 104 - Trang 67-79 - 2011
Bernhard Schulz, Jürgen F. von Raumer
The pre-Mesozoic, mainly Variscan metamorphic basement of the Col de Bérard area (Aiguilles Rouges Massif, External domain) consists of paragneisses and micaschists together with various orthogneisses and metabasites. Monazite in metapelites was analysed by the electron microprobe (EMPA-CHIME) age dating method. The monazites in garnet micaschists are dominantly of Variscan age (330–300 Ma). Garne...... hiện toàn bộ
Laboratory organic matter maturation at high pressures: heat-up effect on vitrinite reflectance
Swiss Journal of Geosciences - Tập 105 - Trang 171-181 - 2012
Ronan Le Bayon
A laboratory study was conducted to assess the effect of heat-up to high diagenetic to low metamorphic temperatures on vitrinite reflectance (VR) at high pressures using the same heat-up processes, apparatus and starting material as those employed in prior experimental studies on huminite/vitrinite maturation. “Heat-up” is the isobaric increase in temperature of an organic matter maturation experi...... hiện toàn bộ
A new basal actinopterygian fish from the Late Ladinian of Monte San Giorgio (Canton Ticino, Switzerland)
Swiss Journal of Geosciences - Tập 106 - Trang 219-230 - 2013
Cristina Lombardo
A new taxon of Late Ladinian basal actinopterygian is described on the basis of a single specimen from the Meride Limestone (Kalkschieferzone) of Meride (Canton Ticino, Switzerland). The species is characterized by a single plate-like branchiostegal, a suboperculum larger than the operculum, a maxillary fixed and posteriorly expanded, a large and rectangular dermopterotic and a large triangular de...... hiện toàn bộ
Eoalpine tectonics of the Eastern Alps: implications from the evolution of monometamorphic Austroalpine units (Schneeberg and Radenthein Complex)
Swiss Journal of Geosciences - Tập 104 - Trang 471-491 - 2011
Kurt Krenn, Walter Kurz, Harald Fritz, Georg Hoinkes
Monometamorphic metasediments of Paleozoic or Mesozoic age constituting Schneeberg and Radenthein Complex experienced coherent deformation and metamorphism during Late Cretaceous times. Both complexes are part of the Eoalpine high-pressure wedge that formed an intracontinental suture and occur between the polymetamorphosed Ötztal–Bundschuh nappe system on top and the Texel–Millstatt Complex below....... hiện toàn bộ
Polyphase greenschist-facies reactivation of the Dent Blanche Basal Thrust (Western Alps) during progressive Alpine orogeny
Swiss Journal of Geosciences - Tập 110 - Trang 503-521 - 2017
Frederik Kirst
This study assesses the significance, geometry, and kinematics of greenschist-facies deformation along the Dent Blanche Basal Thrust (DBBT), a major tectonic contact in the Internal Western Alps of Switzerland and Italy. The DBBT separates continental units of the Dent Blanche nappe, the structurally highest unit in the Western Alps, from underlying Piemont-Ligurian ophiolites. Mylonites and defor...... hiện toàn bộ
Preface: Proceedings of the 5th International Symposium on Lithographic Limestone and Plattenkalk
Swiss Journal of Geosciences - Tập 104 - Trang 1-4 - 2011
Daniel Marty, Jean-Paul Billon-Bruyat, Christian A. Meyer, Loïc Costeur, Basil Thüring
Along-strike shear-sense reversal in the Vals-Scaradra Shear Zone at the front of the Adula Nappe (Central Alps, Switzerland)
Swiss Journal of Geosciences - - 2017
Jacek Kossak-Glowczewski, Nikolaus Froitzheim, T. Nagel, Jan Pleuger, Ruth Keppler, Bernd Leiss, Verena Régent
The Cretaceous of the Swiss Jura Mountains: an improved lithostratigraphic scheme
Swiss Journal of Geosciences - Tập 109 - Trang 201-220 - 2016
André Strasser, Jean Charollais, Marc André Conrad, Bernard Clavel, Antoine Pictet, Bruno Mastrangelo
In the course of the HARMOS project of the Swiss Geological Survey, the lithostratigraphic subdivisions of the Cretaceous sedimentary rocks outcropping in the Swiss Jura Mountains were revisited. New formation names are proposed where only inadequate facies terms existed so far. As in some cases outcrop conditions in the Swiss Jura do not allow for logging complete sections to characterise the for...... hiện toàn bộ
Evolutionary history of hoofed mammals during the Oligocene–Miocene transition in Western Europe
Swiss Journal of Geosciences - Tập 106 - Trang 349-369 - 2013
Laureline Scherler, Bastien Mennecart, Florent Hiard, Damien Becker
The biostratigraphy and diversity patterns of terrestrial, hoofed mammals help to understand the transition between the Palaeogene and the Neogene in Western Europe. Three phases are highlighted: (1) the beginning of the Arvernian (Late Oligocene, MP25-27) was characterised by a “stable” faunal composition including the last occurrences of taxa inherited from the Grande Coupure and of newly emerge...... hiện toàn bộ
A large skull of Ichthyosaurus (Reptilia: Ichthyosauria) from the Lower Sinemurian (Lower Jurassic) of Frick (NW Switzerland)
Swiss Journal of Geosciences - Tập 101 - Trang 617-627 - 2008
Michael W. Maisch, Achim G. Reisdorf, Rudolf Schlatter, Andreas Wetzel
An incomplete skull of an ichthyosaur attributed to Ichthyosaurus communis Conybeare 1822 is reported from the Lower Sinemurian calcarenites (upper part of the “Beggingen Member”, previously “Arietenkalk”, Semicostatum zone) of Frick (Canton Aargau, northern Switzerland). It is the first record of this genus and species in Switzerland, and the first definite record of the genus Ichthyosaurus from ...... hiện toàn bộ
