• Resumen

  • A new record o f magmatism is represented in the Denuy area (Huesca, Central Pyrenees) and is composed by two kind of products: a) basaltic dikes and b) volcaniclastic materials, which include xenoliths from upper and lower hercynian crust. The stratigraphic and structural study of the outcrop indicates a pluriepisodic phreatomagmatic process and suggest a late-hercynian to pre-alpine range of age.
