Entwicklung einer fluidbeeinflussten Scherzone am Beispiel der Glarner Hauptüberschiebung (Schweiz)
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Lokalisierung unter retrograden Deformationsbedingungen kann häufig in groß-maßstäblichen Scherzonen beobachtet werden. Dabei nimmt die Scherzonenbreite kontinuierlich ab. Gleichzeitig passt sich das Gefüge (Korngröße, Kornform, ... -
Extensional crustal-scale shear zones in the Western Cyclades (Kea, Greece)
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Intense seismicity and intensely developed active and ancient fault systems are common to the Aegean Region. Extending/ thinning crust involves a complex interplay of (1) Gulf of Corinth riftexpansion, (2) west- and ... -
Feldspar deformation in greenschist facies shear zones (Aar-Massif, Switzerland)
Hauten, Sarah;
; Dobmeier, Christoph (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Granitic gneisses of the Central Aar Granite host a shear zone network that formed at greenschist facies conditions. The work area is located in the Bächlital (Grimsel area, Central Switzerland) and was chosen for the analysis ... -
Kinematics and deformation structures in a crustal-scale shear zone on Kea (W. Cyclades, Greece)
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)It is generally agreed upon that the exhumation of metamorphic rocks in the Aegean is caused by post orogenic extension in the late Oligocene to early Miocene. This extension is in principle largely accommodated by ... -
Kinematics of the SEMPfault in the western Tauern Window (Stillupp Valley)
; Rosenberg, Claudio (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
The working area is located in the Stillupp Valley (Tirol, Austria), where the western termination of the SEMPfault (Salzach, Ennstal, Mariazell, Puchberg), overprints the northernmost margin of the Zentralgneiss. This ... -
Kinematik des Deckenkontaktes zwischen der Combinzone und der Zermatt-Saas-Zone (Penninische Decken, Westalpen) und deren Bedeutung für die Exhumierung der Zermatt-Saas-Zone
Pleuger, Jan; Roller, Sybille;; Jansen, Ekkehard; Froitzheim, Nikolaus (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Die Grenze zwischen zwei ophiolithischen Decken der penninischen Alpen, der Zermatt-Saas-Zone (unten) und der Combinzone (oben), markiert zugleich einen bedeutenden Sprung der bei der tertiären alpinen Metamorphose ... -
Late stage evolution of the Serifos Metamorphic Core Complex (Cyclades, Greece)
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The island of Serifos is located in the Western Cyclades within the Attic- Cycladic metamorphic belt. It represents the westward continuation of an arcuate belt of Metamorphic Core Complexes with intrusions of late ... -
Scherzonen- und Schuppenbildung am Kontakt von im Bereich der Engelhörner, Berner Oberland (Schweiz)
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Das Untersuchungsgebiet umfasst den Nordrand des Aarmassivs, die autochthone und paraautochthone sedimentäre Bedeckung des Aarmassivs, den ultrahelvetischen Wildflysch und den Südrand der Wildhorndecke. Das Aarmassiv besteht ... -
Structural investigations of the W termination of the ‘Schneeberg Zug’ — Austroalpine Unit, Southern Tyrol: Results from a crustal scale shear zone
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Austroalpine microplate traces the Alpine collision event between the Africa-related southern Alpine realm and the European continent. The southern margin of this microplate, the basement to the north of Meran ... -
The role of the Ranotsara Zone in southern Madagascar for Gondwana correlations
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The Precambrian basement of southern Madagascar was reworked at high-grade metamorphic conditions during the East African Orogen (EAO of Stern, 1994) that formed during assembly of Gondwana in late Neoproterozoic/early ... -
The Serifos Metamorphic Core Complex (Greece) — kinematic investigations of the southern detachment mylonites
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006)The island of Serifos is situated about 100km SSE of Athens in the Aegean Sea and belongs to the Attic-Cycladic massif. The geology of Serifos is largely characterized by a shallow hornblendebiotite granodiorite pluton ... -
Very high anisotropies of the magnetic susceptibility in ductile shear zones: first quantitative results from a metamorphic nappe in the Central Scandinavian Caledonides, Sweden
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Shear zones in the Seve crystalline basement nappes of the central Scandinavian Caledonides contributed to exhumation and translation of these highgrade metamorphic rocks. The Seve unit is considered to represent the ...
