...Rosangela Bocchio; Luisa De Capitani; Luisa Ottolini Abstract In the area of Gorduno, near Bellinzona, Central Alps, Switzerland, well-preserved eclogites crop out only at the margin of the garnet peridotite massif of Alpe Arami (AA). These bodies of eclogite were not derived from cognate mafic...

... of this paper. For comparison, boxes A1–A5 (accompanied by dates) describe a similar exhumation curve for the Alpe Arami massif, Switzerland ( Brenker and Brey 1997 ). Open circle is Alpe Arami P / T from Ernst (1978) ; filled circle is from Medaris and Carswell (1990) . Dashed line with question marks...

... . During the complex geological history of the Alpe Arami massif, several metamorphic events are recorded, all of which could have caused redistribution of the mineral components. In particular, olivine of these rocks is variably recrystallized. The younger generation of olivine exhibits no oxide...

..., we compare the new find with that at Alpe Arami and other localities. The oval-shaped metamorphic complex of the Saxonian Erzgebirge is part of the Variscan Bohemian Massif in central Europe. In the Gneiss-Eclogite Unit (GEU) of this crystalline complex, a few serpentinized garnet peridotite...

... by Dobrzhinetskaya et al. (1996) from the Alpe Arami massif. From TEM electron diffraction patterns, these authors suggested that the (Fe,Mg)TiO 3 rods have three different structures previously unrecognized. They proposed that the originally unexsolved phase was the high-pressure perovskite-structured polymorph...

...Esther Schmädicke; Jürgen Gose Data on water in nominally anhydrous minerals (NAMs) of orogenic garnet-bearing ultramafic rocks (GBU) are extremely rare. In this study, garnet of peridotite and pyroxenite from Erzgebirge (EG), Germany, and two peridotite samples from Alpe Arami (AA), Switzerland...
