High temperature - Low pressure tectonites from the Boa Fé Fault Zone (Évora Massif, Ossa Morena Zone, Portugal): Evidences for transtensional tectonics

Partial melting in the Évora Massif (Ossa-Morena Zone) occurred contemporaneously with non-coaxial deformation in a transcurrent regime. An example of this fact has been taken from studied partially melted biotite-sillimanite-K-feldspar-andalusite-cordierite tectonites from the Boa Fé Fault Zone. Th...
