A further step toward a thermochronological 3-D model of the SE Black Forest
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Fission-track (FT) data always depend on the thermal history of a 3-D geological complex. Therefore it is expedient to display FT data sets in 3-D models. Such a model in which tectonic, sedimentological and hydrological ... -
High field strength element systematics and Lu-Hf & Sm-Nd garnet geochronology of orogenic eclogites
(Univ. Frankfurt (Main), 2008)Concerning the Bulk Silicate Earth (BSE), the depleted mantle and the continental crust are thought to balance the budget of refractory and lithophile elements, resulting in complementary trace element patterns. However, ... -
Low-temperature thermochronology - methodological studies and application in collisional orogens$nElektronische Ressource
(Univ. Freiberg, 2008)Die Spaltspuren-Datierung als wesentliche Methode aus dem Bereich der Niedrigtemperatur-Thermochronologie basiert auf der Zählung und Messung geätzter Spuren unter dem Mikroskop. Für eine akkurate Altersbestimmung ist daher ... -
Perturbation of isotherms below topography: constraints from tunnel transects through the Alps, Gotthard road tunnel
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)For many years it has been known that near surface isotherms are influenced by the topography (Lees 1910). Recently, a number of studies were pursued to quantify the effect of topography on low temperature isotherms ... -
Reconstruction of the Phanerozoic tectono-thermal history of central and southern Madagascar, based on fission track thermochronology
(Univ. Bremen, 2004)Madagascar, Gondwana, thermochronology. - Titanite and apatite fission track (FT) thermochronology on 127 basement and 18 sedimentary rock samples from central and southern Madagascar record a complex cooling and denudation ... -
Two-dimensional finite element models of convective heat transfer in the upper crust — implications for the interpretation of fission-track data
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Fission-track (FT) thermochronology is a tool routinely used for studies of surface denudation because of its sensitivity to the low temperatures found in the uppermost part of the crust. FT ages and associated track length ... -
(U-Th)/He thermochronology — methodology and a case study: dating of faulting in the Southern Alps
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The radiogeic 4He isotope is continuously forming in the lithosphere mainly by the alpha-decay of U, Th and Sm. This decay process was discovered already at the beginning of the 20th century, and the first U/He dating ...
