Calcretos da região de Elvas : Estudo preliminar
Mesquita Soares, Sofia; Dias, Ruben; Ressurreição, Ricardo; Morais, Igor; Albardeiro, Luís; Gonçalves, Pedro; Solá, A. Rita; Castro-Pina, M.RESUMO: A construção de uma via-férrea no Nordeste Alentejano atravessando a Zona de Ossa-Morena permitiu estudos detalhados focados nas unidades geológicas e na estrutura da área. Na região de Elvas, o Miocénico é representado por um conglomerado coberto por lutitos, mais grosseiro perto da falha de Messejana, onde apresenta basculamento tectónico. Os sedimentos e as rochas do substrato estão fortemente afetad...
Use of mining wastes for high-tech thermoelectric applications : The case of ST...
Morais, Igor; de Oliveira, Daniel Pipa Soares; Silva, Teresa; Albardeiro, Luís; Salgueiro, Rute; Neves, FilipeABSTRACT: Europe aims to become the first climate neutral continent by 2050, which means rapidly implementing a green transition to which the European Union (EU) is strongly committed through the European Green Deal. This green transition leverages unprecedented pressure on the intensive use of mineral resources. In this context the START project “Sustainable Energy Harvesting Systems Based on Innovative Mine W...

Feitoza, L. M.; Carvalho, João; Represas, Patricia; Ramalho, Elsa; Sousa, Pedro; Matos, João Xavier; Albardeiro, Luís; Morais, IgorABSTRACT: The Cercal Volcano-Sedimentary Complex (Cercal VSC) structure is the westernmost sector of the Iberian Pyrite Belt (IPB) giant metallogenic province and was explored since Roman times for volcanogenic massive sulphides (VMS) and Fe–Mn (Ba) deposits. However, presently only a single deposit is known, the Salgadinho Cu-Ag-Au stockwork/disseminated deposit. Nevertheless, according to several mining compa...
Unlocking the Secondary Critical Raw Material Potential of Historical Mine Site...
de Oliveira, Daniel Pipa Soares; Gonçalves, Pedro; Morais, Igor; Silva, Teresa; Matos, João Xavier; Albardeiro, Luís; Filipe, AugustoABSTRACT: A steady supply of mineral raw materials is vital for the transition to a low-carbon, circular economy. The number of active mines in Europe has severely declined over the last century and half, giving rise to many abandoned mining waste sites and corresponding geological heritage. Also, the rise in minerals demand for large-scale deployment of renewable energy requires the continued and steady availa...

The age and depositional environments of the lower Karoo Moatize Coalfield of M...
Fernandes, Paulo; Hancox, J.; Mendes, Márcia; Pereira, Zélia; Lopes, Gilda; Marques, João; Jorge, Raul CG Santos; Albardeiro, LuísABSTRACT: The Moatize Coalfield belongs to a network of continental Karoo basins of central Mozambique, known as the Zambezi Basin. Palynological and sedimentological studies were performed on four coal exploration boreholes to determine the age, depositional settings, and overall geological evolution of its extensive coal deposits. Clastic formations recognised in this coalfield, in ascending order, are the Vú...
