Palynostratigraphy of the Toca da Moura and Cabrela Complexes, Ossa Morena Zone, Portugal. Geodynamic implications

Palynological assemblages obtained from the Ossa Morena Zone are comparable to those recognized from the Late Devonian and Mississippian of the South Portuguese Zone. Similarities between the assemblages from the two crustal blocks show that they were close to each other during this interval. Thus, the oceanic basin that existed between the two blocks and to which the Beja-Acebuches Ophiolite is related was closed prior Late Devonian.
