Ranked Mappable Criteria for Magmatic Units: Systematization of the Ossa-Morena...
Roseiro, José; Moreira, Noel; de Oliveira, Daniel; Silva, Marcelo; Eguiluz, Luis; Nogueira, PedroThe Ossa-Morena Zone (SW Iberian Massif) hosts the largest set of Cambro–Ordovician alkaline magmatic plutons related to the Palaeozoic rifting of the northern Gondwana margin so far described. An organized framework for their classification at different scales is proposed through data-driven ranks based on their distinctive petrological features relative to other rift-related magmatic rocks found throughout we...
High strain peralkaline orthogneisses within orogenic scale shear zones: geolog...
Roseiro, José; Moreira, Noel; Nogueira, Pedro; de Oliveira, DanielThe lithological units in the Arronches region (included within the Arronches tectonic unit, Tomar-Badajoz-Córdoba Shear Zone, northernmost Ossa-Morena Zone) and in particular the peralkaline orthogneisses therein, have been the target for petrological, geochemical and structural studies in order to constrain its petrogenesis and tectono-metamorphic contextualization within the broader regional geology. Two det...
Variscan tectono-metamorphic recrystallization of Cambro-Ordovician feldspathic...
Roseiro, José; Moreira, Noel; de Oliveira, Daniel; Nogueira, PedroThe alkaline magmatic rocks emplaced during the Cambro-Ordovician rifting of north Gondwana consist of alkaline granites, syenites and albitites variably deformed during the Variscan Orogeny. They are located in in the central-northern domains of the Ossa-Morena Zone (SW Iberia), within areas that experienced varying tectono-metamorphic conditions during the late Palaeozoic, ranging from low-grade to high-grade...
Exploring Learning Techniques in Language Models for Classifying Hate and Offen...
Assis, Gabriel; Amorim, Annie; Carvalho, Jonnathan; Ferro, Mariza; de Oliveira, Daniel; Vianna, Daniela; Paes, Aline Social Media platforms, significant in modern debate and communication, face the challenge of managing a vast and disorderly volume of hateful content and disinformation. This work examines the detection of hate speech in Portuguese, contemplating its unique linguistic and cultural nuance. Leveraging Transformer-based models and different training and activation strategies, nine models with variations in ...
Contact metamorphism and dolomitization overprint on Cambrian carbonates from t...
Roseiro, José; Moreira, Noel; Andrade, Laura; Nogueira, Pedro; de Oliveira, Daniel; Eguiluz, Luis; Mirão, José; Moita, Patrícia; Santos, José FranciscoThe Cambrian Series 2 Carbonate Formation from the Alter do Chão Elvas-Cumbres Mayores unit (Ossa-Morena Zone, SW Iberian Massif) is composed of regionally metamorphosed marbles and marlstones that underwent chlorite zone metamorphism and preserve the primaeval limestone 87Sr/86Sr ratios (0.7083–0.7088). These are consistent with the established Lower Cambrian seawater curve, and therefore used for age constrai...
Classificação sistemática de unidades magmáticas: exemplo das rochas alcalinas ...
Roseiro, José; Moreira, Noel; Nogueira, Pedro; de Oliveira, DanielThe systematic classification of non-stratiform units provides a harmonized setting that can be used as a basis for mapping at different scales, correlating geological terrains, and conducting subsequent studies focused on petrogenesis or metagenesis. Here, a classification method based on 6 ranks is proposed for the alkaline rocks (s.l.) of the Ossa-Morena Zone (OMZ), emplaced during the Paleozoic rift and dis...
Caracterização preliminar da deformação dos ortognaisses alcalinos e hiperalcal...
Roseiro, José; Moreira, Noel; Nogueira, Pedro; de Oliveira, DanielIn the Blastomylonitic Belt (northernmost Ossa-Morena Zone), alkaline and peralkaline orthogneisses are found as elongated bodies with WNW-ESE to NW-SE orientation hosted within a strongly deformed Neoproterozoic to Lower Cambrian metasedimentary strata. Despite some similarities between them (ascribed to the very similar nature of their igneous protolith) the deformational features displayed in all of them are...
Revisiting geochemical data from the Ossa-Morena Zone peralkaline rocks: New in...
Roseiro, José; Moreira, Noel; Nogueira, Pedro; de Oliveira, Daniel; Eguiluz, LuisIn SW Iberia (namely in the northernmost domains of Ossa-Morena Zone [OMZ]), NW-SE lineaments of peralkaline igneous massifs are found, known to have been emplaced during the Cambrian-Ordovician rift-related magmatic stage of the Variscan extension in northern Gondwana. In the Portuguese counterpart of the OMZ, these rocks can be found in two distinct tectono-stratigraphic segments, namely the Blastomylonitic B...
Professional qualification in Physical Education and unified health system
Manske, George Saliba; de Oliveira, DanielThe present article is part of a broader discussion on the vocational training ofprofessionals involved in the Healthcare Field. My aim is to identify the degree ofknowledge hold by students of Physical Education, from a College institution in SantaCatarina, in regard to their attainment to the Primary Care in Public Health System(SUS) through specific professional practices in the Support Center for Family Hea...
