Age constraints on faulting and fault reactivation: a multi-chronological approach
Siebel, Wolfgang; Hann, Horst; Danišík, Martin; Shang, Cosmas; Berthold, Christoph; Rohrmüller, Johann; Wemmer, Klaus
; Evans, Noreen (International Journal of Earth Sciences, 2009)
Movement within the Earth’s upper crust is commonly accommodated by faults or shear zones, ranging in scale from micro-displacements to regional tectonic lineaments. Since faults are active on different time scales and can ... -
Contemporaneous assembly of Western Gondwana and final Rodinia break-up: Implications for the supercontinent cycle
Oriolo, Sebastián; Oyhantçabal, Pedro; Wemmer, Klaus; Siegesmund, Siegfried (Geoscience Frontiers, 2017)
Geological, geochronological and isotopic data are integrated in order to present a revised model for the Neoproterozoic evolution of Western Gondwana. Although the classical geodynamic scenario assumed for the period ... -
Do U/Pb-SHRIMP Dating and Pb Stepwise Leaching (PbSL) Analyses Confirm the Lack of Precambrian Basement Outcrops in Thailand?
Hansen, Bent T.; Wemmer, Klaus; Putthapiban, Prinya; Kleinhanns, Ilka C.; Wilsky, Franziska (Open Journal of Geology, 2014)
U/Pb-SHRIMP dating and Pb stepwise leaching (PbSL) experiments on zircons and garnets, respectively have confirmed the lack of Precambrian outcrops within the crystalline basement of Thailand. The obtained data for the ... -
Exhumation and uplift of the Sierras Pampeanas: preliminary implications from K–Ar fault gouge dating and low-T thermochronology in the Sierra de Comechingones (Argentina)
Löbens, Stefan; Bense, Frithjof; Wemmer, Klaus; Dunkl, István
; Costa, Carlos; Layer, Paul; Siegesmund, Siegfried (International Journal of Earth Sciences, 2011)
The Sierras Pampeanas in central and north-western Argentina constitute a distinct morphotectonic feature between 27°S and 33°S. The last stage of uplift and deformation in this area are interpreted to be closely related ... -
Exhumation history and landscape evolution of the Sierra de San Luis (Sierras Pampeanas, Argentina) - new insights from low - temperature thermochronological data

This paper presents low-temperature thermochronological data and K‑Ar fault gouge ages from the Sierra de San Luis in the Eastern Sierras Pampeanas in order to constrain its low-temperature thermal evolution and ... -
Geologische Exkursion Südost-Schweden - Schonen, Blekinge, Öland, Region Västervik
Das breite inhaltliche Spektrum der vorgestellten Region auf dem Kraton Baltica (Präkambrisches Grundgebirge, Deckgebirge, Deformationszonen, Quartärgeologie) eignet sich sehr gut für eine allgemeingeologische Exkursion ... -
Isotope Dating of the Potash and Rock Salt Deposit at Bamnet Narong, NE-Thailand
Hansen, Bent T.; Wemmer, Klaus; Eckhardt, Monique; Putthapiban, Prinya; Assavapatchara, San (Open Journal of Geology, 2016)
Bamnet Narong is located in northeastern Thailand (Chaiyaphum Province). It is the largest salt mine in the country and has been mined for decades. The landscape in this part of Thailand is characterised by a low plateau, ... -
Petrology, magnetostratigraphy and geochronology of the Miocene volcaniclastic Tepoztlán Formation: implications for the initiation of the Transmexican Volcanic Belt (Central Mexico)
Lenhardt, Nils; Böhnel, Harald; Wemmer, Klaus; Torres-Alvarado, Ignacio; Hornung, Jens
; Hinderer, Matthias (Bulletin of Volcanology, 2010)
The volcaniclastic Tepoztlán Formation (TF) represents an important rock record to unravel the early evolution of the Transmexican Volcanic Belt (TMVB). Here, a depositional model together with a chronostratigraphy of this ... -
Post-Caledonian brittle deformation in the Bergen area,West Norway: results from K–Ar illite fault gouge dating
Ksienzyk, Anna K.; Wemmer, Klaus; Jacobs, Joachim
; Fossen, Haakon
; Schomberg, Anna C.; Süssenberger, Annette; Lünsdorf, N. Keno
; Bastesen, Eivind (Norwegian Journal of Geology, 2016)
Post-Caledonian extension during orogenic collapse and Mesozoic rifting in the West Norway–northern North Sea region was accommodated by the formation and repeated reactivation of ductile shear zones and brittle faults. ... -
Provenance of the Bosnian Flysch
Mikes, Tamás; Christ, Dominik; Petri, Rüdiger; Dunkl, István; Frei, Dirk; Báldi-Beke, Mária; Reitner, Joachim
; Wemmer, Klaus
; Hrvatović, Hazim; Eynatten, Hilmar (Swiss Journal of Geosciences, 2008)
Sandwiched between the Adriatic Carbonate Platform and the Dinaride Ophiolite Zone, the Bosnian Flysch forms a c. 3000 m thick, intensely folded stack of Upper Jurassic to Cretaceous mixed carbonate and siliciclastic ... -
The Neoproterozoic-early Paleozoic metamorphic and magmatic evolution of the Eastern Sierras Pampeanas: an overview
Steenken, André; López de Luchi, Mónica; Martínez Dopico, Carmen; Drobe, Malte; Wemmer, Klaus; Siegesmund, Siegfried (International Journal of Earth Sciences, 2010)
The Eastern Sierras Pampeanas were structured by three main events: the Ediacaran to early Cambrian (580–510 Ma) Pampean, the late Cambrian–Ordovician (500–440 Ma) Famatinian and the Devonian-Carboniferous (400–350 Ma) ... -
