Partially Melted Crustal Xenoliths as a Window into Sub-Volcanic Processes: Evidence from the Neogene Magmatic Province of the Betic Cordillera, SE Spain

Abstract:

Crustal xenoliths from the NeogeneVolcanic Province (NVP) of the Betic Cordillera, SE Spain, constitute an unusual suite of high-grade melt-bearing metapelitic rocks derived in two stages from metasediments surrounding crustal magma chambers. Microstructures and age relationships indicate that a first stage of migmatization and melt extraction was overprinted by a sequence of melt-bearing reaction microstructures. The preservation of melt as glass requires only a short residence time before e...
