The record of Deinotheriidae from the Miocene of the Swiss Jura Mountains (Jura Canton, Switzerland)

Gagliardi, Fanny ; Maridet, Olivier ; Becker, Damien

In: bioRxiv, 2021, p. 244061

The Miocene sands of the Swiss Jura Mountains, long exploited in quarries for the construction industry, have yielded abundant fossil remains of large mammals. Among Deinotheriidae (Proboscidea), two species, Prodeinotherium bavaricum and Deinotherium giganteum, had previously been identified in the Delémont valley, but never described. A third species, Deinotherium levius, from the locality of...

Multiple detachments during thin-skinned deformation of the Swiss Central Jura: a kinematic model across the Chasseral

Schori, Marc ; Mosar, Jon ; Schreurs, Guido

In: Swiss Journal of Geosciences, 2015, vol. 108, no. 2-3, p. 327–343

Combining field observations, cross-section area balancing techniques and kinematic forward modelling, we present new insights into the evolution of the Jura fold-and-thrust belt in the Chasseral area between Lake Biel and the Vallon de St-Imier, in the Canton of Bern, Switzerland. Our results show that the structures of the Chasseral area and the associated regional uplift can be explained by...

Une nappe alluviale étagée du Pléistocène supérieur dans la vallée de Delémont (Jura suisse) : lithostratigraphie et datation

Braillard, Luc ; Guélat, Michel

In: Quaternaire, 2008, vol. 19, no. 3, p. 217-228

La vallée de Delémont, dans le Jura suisse, est caractérisée par un système de trois nappes alluviales étagées, T1, T2 et T3, mises en place en contexte périglaciaire. Cet article présente la stratigraphie détaillée de la plus haute de ces terrasses, T3, correspondant à des graviers fluviatiles revêtus par des dépôts limoneux qui montrent un horizon fragipan et des polygones de gel...

Clay resources and technical choices for neolithic pottery (Chalain, Jura, France): chemical, mineralogical and grain-size analyses

Martineau, R. ; Walter-Simonnet, A.-V. ; Grobéty, Bernard ; Buatier, M.

In: Archaeometry, 2007, vol. 49, no. 1, p. 23–52

Many authors have considered pottery manufacturing constraints and sociocultural elements as factors in change in past civilizations over time. The main issue of this research is to better understand the reasons for changes, or choices, in pottery raw materials. The very precise and detailed stratigraphy and cultural succession of occupations is based on dendrochronological data from the...
