The Galicia–Ossa-Morena Zone: Proposal for a new zone of the Iberian Massif. Variscan implications [PDF]
Tectonophysics, 2016 Correlation of a group of allochthonous terranes (referred to as basal, ophiolitic and upper units) exposed in the NW and SW of the Iberian Massif, is used to propose a new geotectonic zone in the southern branch of the Variscan Orogen: the Galicia–Ossa ...

87Sr/86Sr applied to age discrimination of the Palaeozoic carbonates of the Ossa-Morena zone (SW Iberia Variscides) [PDF]
International Journal of Earth Sciences, 2019 Four distinct Palaeozoic episodes of marine carbonate sedimentation are reported in the Ossa-Morena Zone (SW Iberian Variscides). Among them, the Cambrian and the Devonian episodes are those that are well represented in the Portuguese domains of the Ossa-

Mineral chemistry dataset of the Tournaisian – Lower Viséan submarine basaltic volcanism of the Matachel Basin (SW Iberian Massif). [PDF]
Data in Brief, 2023 The Matachel Basin is a tectono-stratigraphic unit of Ossa-Morena Zone (southern Iberian Massif) that encompasses an Upper Tournaisian – Viséan basaltic sequence, generated by effusive and explosive eruptions in a shallow submarine setting.

Reorganization of Northern Peri-Gondwanan Terranes at Cambrian–Ordovician Times: Insights from the Detrital Zircon Record of the Ossa-Morena Zone (SW Iberian Massif) [PDF]
Lithosphere, 2022 The Ossa-Morena Zone constitutes a fringe Gondwana-related terrane all along the Paleozoic. This continental block has been classically interpreted as being attached to a portion of the northern Gondwanan margin located close to the West African Craton ...
