Visibile a: nessunoAbstractIn south western Norway emerges the Western Gneiss Region, an area generated during the Paleozoic through the Caledonian orogeny. The tectonic event begins approximately 490Ma during the Ordovician, and moncler outlet online uomo ends at 400mA moncler outlet online shop in the Lower Devonian. this thesis we analyzed two moncler outlet trebaseleghe samples of piumini moncler uomo eclogites from this metamorphic region. The samples come from mafic material of the continental crust, reaching subduction to piumini moncler saldi depths piumini moncler greater than 100km. The peak in eclogite moncler saldi outlet facies is reached at 760 C and 3.0GPa. shows a series of mineralogical associations, containing garnet, plagioclase, moncler outlet serravalle biotite, clinopyroxene. in the rocks are characterized by very stretched and deformed aspect. Optical microscope shows a mosaic structure constituted by the presence of many grains at sub millimeter scale. moncler bambino saldi SEM analysis providing outlet moncler insight into the microstructure and the EBSD moncler donna is used to observe the deformation process that has interested the garnet. a microscopy is evident that the garnet is present in mosaic structures, piumini moncler outlet with grains united by joints triple and regular limits. Inside the grains are absent secondary mineral phases, there is no zoning chemistry and there is a edge of decomposition in amphibole around the moncler saldi mosaic. of EBSD indicate has been active the piumini moncler scontatissimi mechanism of grain boundary sliding, that causes a random orientation of the crystal lattice moncler outlet with each other. The microstructures also suggest that moncler uomo they may have been active mechanisms of ductile deformation, such as dislocation creep. FF.
