The tectono-metamorphic evolution of the European Alps is still contentious. Monte Rosa tectonic unit a prominent nappe in Central and estimates its peak Alpine pressure (P) temperature (T) conditions are essential for reconstructing evolution. However, reported vary considerably between 1.2 2.7 GPa 490 640°C variety lithologies. Here, we show petrology pseudosection modelling metapelitic assem...

in order to assess the presence or absence of fluids under peak metamorphic conditions within the inner aureole of the etive igneous complex in west scotland, eight suitable metabasic hornfels samples and one suitable pelitic hornfels were used to calculate water activities using a mineral equilibria. calculated activities for water are lower than unity in the pelitic sample and extremely low i...

some small gabbro patches emplaced along the thrust fault with w-e trend in the vicinity of maien bolagh village at the ht/mp metapelites, a part of the central iran zone (near to sanandaj-sirjan zone). the coarse-grained dark gabbro samples consist of amphibole, clinopyroxene, plagioclase, minor quartz, titanite, and biotite. gabbros have high potassic calc-alkaline to shoshonitic affinity. th...
