Abstract: | Petrographic, chemical and mineralogical data are presented on the Oetztal eclogites and their co-existing minerals. The available evidence indicates that they constitute the metamorphic derivates of an original gabbroic rock, the plagioclase and clinopyroxene of which reacted to form the garnet, omphacite and kyanite components of the eclogites. According to the available subsolidus experimental data these reactions are believed to have taken place in a 6–10 kb pressure range at about 550°–750° C. |
