Structure and kinematics of the northern Simano Nappe, Central Alps, SwitzerlandEclogae Geologicae Helvetiae - Tập 98 - Trang 63-81 - 2005
Roger Rütti, Michael Maxelon, Neil S. Mancktelow
New structural data allow the internal structure and kinematics of the Lower Penninic Simano Nappe to be established, together with the relationship of this unit to the underlying Leventina Gneisses and the also underlying Maggia Nappe. Three clearly distinguishable Alpine deformation phases (D1, D2, D3) are recognized within the Simano Nappe. D1 developed in mid-crustal levels under metamorphic c...... hiện toàn bộ
An Eocene paleodoline in the Morcles Nappe of Anzeindaz (Canton of Vaud, Switzerland)Eclogae Geologicae Helvetiae - Tập 98 - Trang 51-61 - 2005
Pascal Linder
In the helvetic Morcles Nappe of Anzeindaz (Canton of Vaud, Switzerland), Eocene sediments document the successive bypassing of the forebulge and foreland basin of the Alpine orogeny. Cretaceous sediments are cut off by the major erosive unconformity of the so-called “siderolithic” emersion phase. This persistent phase of continental exposure and erosion caused by the presence of the forebulge dur...... hiện toàn bộ
Evolution diagénétique dans la craie pélagique dolomitisée du crétacé supérieur du bassin de Paris (région de Provins, France)Eclogae Geologicae Helvetiae - Tập 97 - Trang 393-409 - 2004
Jean-Pierre Gély, Philippe Blanc
Two deep scientific boreholes, named Poigny 701 and Sainte-Colombe 702, located in the Paris Basin near Provins (Seine-et-Marne, France), recovered a complete Upper Cretaceous chalk succession. A correlation between the boreholes lithostratigraphy, reflexion seismic profiles and diagenetic patterns shows that major velocity variations measured in the seismic reflection profiles correspond to dolom...... hiện toàn bộ
Echinoids from the Belpberg Beds (Obere Meeresmolasse, Middle Burdigalian) in the area of Bern (Switzerland)Eclogae Geologicae Helvetiae - Tập 99 - Trang 193-203 - 2006
Andreas Kroh, Ursula Menkveld-gfeller
The present paper deals with the echinoid fauna of the Belpberg Beds, a lithostratigraphic unit in the Upper Marine Molasse cropping out southeast of Bern (Switzerland). In this unit, echinoids, in contrast to mollusks, are rare and of low diversity. The scarcity of echinoids is related to the environmental setting dominated by monotonous siliciclastic deposits and strong diagenetic alteration. Th...... hiện toàn bộ
From extension to transpression during the final exhumation of the Pelvoux and Argentera massifs, Western AlpsEclogae Geologicae Helvetiae - Tập 97 - Trang 429-439 - 2004
Pierre Tricart
Like the other “external crystalline massifs” (ECM) of the Western Alps, the Pelvoux and Argentera massifs record a late and important uplift of the Prealpine basement in the immediate foreland of the internal nappes. Recently published structural and fission track data indicate distinctly different final stages of exhumation for the two massifs. The last main exhumation of the SE Pelvoux basement...... hiện toàn bộ
