A review of the Ossa-Morena Zone and its limits. Implications for the definition of the Lusitan-Marianic Zone. [PDF]
, 2004 The boundary between the Central-Iberian Zone and the Ossa-Morena Zone of the Hesperian Massif has long been placed either in Los Pedroches batholith or in the Badajoz-Cordoba shear zone, using different arguments. Here, based on mainly stratigraphic and

The metallogenic evolution of the Ossa-Morena Zone [PDF]
, 2004 The Ossa-Morena Zone contains abundant ore deposits and showings for the most part formed during the Cadomian and the Variscan orogenic cycles, and the intermediate rifting and stable platform stages.

Devonian Sedimentation in the SW boundary of the Ossa-Morena Zone: State of Art and Paleogeography [PDF]
, 2020 The Devonian sedimentary record of the Ossa-Morena Zone is scarce. In its southwestern domains, the Odivelas Limestone and correlatable units represent the single evidence of latest Early Devonian to Middle Devonia n (possibly into Frasnian ...

Tectonics, Volume 42, Issue 12, December 2023., 2023 Abstract The Cadomian Orogeny produced a subduction‐related orogen along the periphery of Gondwana and configured the pre‐Variscan basement of the Iberian Massif. The architecture of the Cadomian Orogen requires detailed structural analysis for reconstruction because of severe tectonic reworking during the Paleozoic (Variscan cycle). Tectonometamorphic

Chronostratigraphic framework and provenance of the Ossa-Morena Zone Carboniferous basins (SW Iberia) [PDF]
, 2020 Abstract. Carboniferous siliciclastic and silicic magmatic rocks from the Santa Susana-São Cristovão region contain valuable information regarding the timing of synorogenic processes in SW Iberia. In this region of the Ossa-Morena Zone (OMZ), Late Carboniferous terrigenous strata (i.e.

Crustal Imaging of Portugal Mainland Using Magnetotelluric Data
Earth and Space Science, Volume 10, Issue 7, July 2023., 2023 Abstract The comprehensive mapping of resistivities in depth and its interpretation is of great importance to unravel the electrical properties of deep‐seated rocks, providing significant insights into the structure of the crust. The first 3D resistivity model for Portugal mainland is here reported using data from 31 broadband MT soundings spaced 50 ...
