Evidence for partial melting of eclogite occurring in the Bohemian Massif, Czech Republic

Abstract

An eclogite collected from the Bohemian Massif contains leucocratic veins that mainly consist of plagioclase. Melanocratic part of the eclogite mainly comprises of garnet, clinopyroxene and rutile. The leucocratic veins also contain garnet and clinopyroxene. Garnet and clinopyroxene in the leucocratic veins display faceted shapes while those in the melanocratic part show irregular shapes. This probably suggests that the leucocratic veins were originally melt. Clinopyroxene shows approximately the same major- and trace-elements composition between grains in the melanocratic part and faceted shape grains in the leucocratic veins. These suggest that the melt was formed by partial melting of this eclogite.
