A cerâmica fosca, a vidrada e a faiança de Lisboa durante a Época Moderna
Leitão, Eva; Batalha, Luísa; Pereira, Manuel Francisco; Cardoso, GuilhermeDurante séculos, Lisboa foi um centro produtor de cerâmica de excelência. O evoluir da urbe cobriu muitos dos afl oramentos argilosos que existiam, levando praticamente à sua ocultação. As recentes escavações arqueológicas, realizadas em espaços edifi cados de antigos barreiros e olarias, tem possibilitado recuperar parte da antiga memória oleira da metrópole. Os barros vermelhos e brancos, existentes no seu su...
Home trash biomass valorization by catalytic pyrolysis
Rijo, Bruna; Dias, Ana Paula Soares; Jesus, Nicole de; Pereira, Manuel FranciscoWith the increase in population, large amounts of food waste are produced worldwide every day. These leftovers can be used as a source of lignocellulosic waste, oils, and polysaccharides for renewable fuels. In a fixed bed reactor, low-temperature catalytic pyrolysis was investigated using biomass gathered from domestic garbage. Thermogravimetry, under N2 flow, was used to assess the pyrolysis behavior of tea a...
As Rochas Metamórficas e Plutónicas do Rio Almansor: Um Património Geológico a ...
Pereira, Manuel FranciscoNo Rio Almansor, que circunda a cidade de Montemor-o-Novo, encontram-se afloramentos de rochas metamórficas formadas há cerca de 340 milhões de anos, a pelo menos 11 km de profundidade e sob elevadas temperaturas (migmatitos e gnaisses) em associação com rochas magmáticas (rochas graníticas). A geodiversidade aqui observada tem um extraordinário interesse científico e educativo que deve ser preservado e estudad...

The granite‑hosted Variscan gold deposit from Santo António mine in the Iberian...
Neiva, Ana M. R.; Moura, António; Gomes, C. Leal; Pereira, Manuel Francisco; Corfu, FernandoThe study area is located in the Central Iberian Zone, a major tectonic unit of the Iberian Massif (Variscan belt). In this region the basement is composed of Cambrian-Ordovician sedimentary and minor volcanic rocks that underwent deformation and metamorphism during the Carboniferous. These metamorphic rocks host ca. 331–308 Ma granitic plutons emplaced during the D2 extensional and D3–D4 contractional deformat...
Recycling of the Proterozoic crystalline basement in the Coastal Block (Morocca...
El Houicha, Mohamed; Pereira, Manuel Francisco; Jouhari, Abdellatif; Gama, Cristina; Ennih, Nasser; Fekkak, Abdelilah; Ezzouhairi, HassanDetrital zircon age spectra from the siliciclastic rocks of the Lalla Mouchaa Calcschists and El Jadida Dolomitic formations (the Coastal Block of the Moroccan Meseta) are dominated by Paleoproterozoic and Ediacaran ages. The provenance of these two formations is a composite Proterozoic crystalline basement. El Jadida rhyolite (584.2 ± 4.8 Ma) represents the Ediacaran crystalline basement of the El Jadida dome....
Comment on ‘‘Stratigraphy of the Northern Pulo do Lobo Domain, SW Iberia Varisc...
Pereira, Manuel Francisco; Martinez Poyatos, David; Perez Caceres, Irene; Gama, Cristina; Azor, AntonioThe paper by Zelia Pereira et al. (2018) is a valuable input to better constrain the Devonian palynological record of a number of siliciclastic formations of the Pulo do Lobo Unit (also known as Pulo do Lobo Domain or Pulo do Lobo Zone) in SW Iberia. They have recognized for the first time in the Pulo do Lobo Fm. and in the imbricated phyllites of the Peramora Me´lange palynomorph assemblages assigned to the mi...
Detrital provenance of the Upper Triassic siliciclastic rocks from southwest Ib...
Pereira, Manuel Francisco; Gama, CristinaIn southwestern Iberia the Upper Triassic successions of Lusitanian, Alentejo and Algarve basins records the fragmentation of Pangaea in Permian–Triassic during which the paleogeography of Iberia was dominated by a series of coalescing, alluvial–deltaic wedges and axial braided rivers. In this study, we discuss the potential sediment sources of the Lusitanian, Alentejo and Algarve basins based on detrital zirco...
Birth and demise of the Rheic Ocean magmatic arc(s): Combined U–Pb and Hf isoto...
Pereira, Manuel Francisco; Gutierrez-Alonso, Gabriel; Murphy, J. Brendan; Drost, Kerstin; Gama, Cristina; Silva, J. BrandãoPaleozoic continental reconstructions indicate that subduction of Rheic oceanic lithosphere led to collision be- tween Laurussia and Gondwanawhich was a major event in the formation of the Ouachita-Appalachian-Variscan orogenic belt and the amalgamation of Pangea. However, arc systems which record Rheic Ocean subduction are poorly preserved. The preservation of Devonian detrital zircon in Late Devonian–Early Ca...
