- Áreas potenciais de Portugal para recursos minerais do domínio públicoPublication . Carvalho, Jorge; Filipe, Augusto; Gonçalves, Pedro; Lisboa, Jose; Matos, João Xavier; Batista, Maria Joao; Salgueiro, Rute; de Oliveira, Daniel Pipa SoaresSUMMARY: Land-use planning is decisive for granting access to mineral resources. During the work to identify the actions to be taken for preparing the National Strategy for Geological Resources, a map of mineral potential areas for Portugal was produced. It provides the starting point scenario needed for the implementation of a methodology aimed at the delineation of mineral safeguarding areas.

- Critical raw materials deposits map of mainland Portugal: new mineral intelligence in cartographic formPublication . de Oliveira, Daniel Pipa Soares; Filipe, Augusto; Gonçalves, Pedro; Santos, Sara; Albardeiro, LuísABSTRACT: Reliable and unhindered access to raw materials is a growing concern within the EU and across the globe and the demand for Critical Raw Materials (CRM) plays a crucial economic role in most developed countries around the world. These are of extreme importance for supply chains regarding new technologies, sustainability issues and carbon footprint reduction. The definition of a continuously updated list of CRM by the European Commission led to the first CRM Map of Europe in 2016. Following this, several countries have been surveying, preparing, and evaluating their mineral occurrences to create a resources/deposits database and, therefore, to create a CRM map of their own. With this purpose in mind, we present and explain the first Critical Raw Materials Deposits Map of mainland Portugal, at 1:700,000 scale. This paper describes the scientific, technical, and graphical methodologies involved in its design.
- Sentinel 2 : contributo para o conhecimento geológico e recursos minerais [Comunicação oral]Publication . Quental, Lídia; de Oliveira, Daniel Pipa Soares; Dias, Ruben Pereira; Batista, Maria Joao; Matos, João Xavier; Filipe, AugustoRESUMO: As imagens Sentinel 2 são processadas com o objetivo de incrementar o conhecimento geológico e enquadramento de ocorrências minerais, nomeadamente, para suporte na definição de limites litológicos e compreensão de modelos genéticos. Exemplifica-se a N e S de Portugal o contributo da informação espetral.
- SIORMINP : Plataforma de gestão e disponibilização de dados harmonizados dos Recursos Minerais PortuguesesPublication . Patinha, Pedro; Pereira, Aurete; Quental, Lídia; Filipe, Augusto; de Oliveira, Daniel Pipa Soares; Lopes, C.RESUMO: O SIORMINP integra dados relevantes sobre os recursos minerais conhecidos que disponibiliza à sociedade via geoPortal do LNEG. Contudo não é interoperável com sistemas de informação similares europeus. Assim, em projetos europeus é necessário harmonizar os dados de acordo com especificações próprias, que contemplam requisitos da Diretiva INSPIRE. Os dados extraídos do SIORMINP são transformados e armazenados em outras bases de dados, implicando redundância e inconsistência dos dados. Para obviar este paradigma foi criada uma Geodatabase INSPIRE centralizada, para armazenar os dados dispersos por outras bases de dados. O mapeamento entre distintas bases de dados foi executado com uma ferramenta ETL. O desenvolvimento de uma aplicação de BackOffice permitirá o carregamento descentralizado de novos dados na referida Geodatabase. A integração destas aplicações no novo geoPortal, em 2020, permitirá a evolução do SIORMINP para uma plataforma de gestão e disponibilização de dados sobre Recursos Minerais Portugueses harmonizado com a Europa.
- INSPIRE data harmonisation of mineral resources: contribution of MINERALS4EU projectPublication . Lopes, Catarina; Quental, Lídia; De Oliveira, Daniel Pipa Soares; Filipe, Augusto; Pereira, AureteABSTRACT: Georesources support society at different levels, depending on their technological development, and thus strongly impact on the economic, societal and environmental sustainability pillars. The European project MINERALS4EU [5] created the European Mineral knowledge Data platform (EU-MKDP [6]), to provide harmonised data related to mineral resources, as well as statistical related information, e.g., minerals yearbook. The nuclear pillars of the EU-MKDP architecture were based in the datamodels and harmonised terminology developed by INSPIRE and IUGS-CGI (represented by GeoSciML and EarthResourceML). The Portuguese input to this platform was based on mineral occurrences and resources information system, SIORMINP [15]. SIORMINP contains information of categorization of mineral potential, past concessions, commodities reserves and resources, and exploitation activity. The SIORMINP dataset was harmonised according to the MINERALS4EU project data model and vocabularies, and published using OGC compliant Web services in EU-MKDP. This work shows how the data harmonization was undertaken to integrate national database in the EU-MKDP, and more recently to improve the national geoportal to be INSPIRE compliant.

- Unlocking the Secondary Critical Raw Material Potential of Historical Mine Sites, Lousal Mine, Southern PortugalPublication . de Oliveira, Daniel Pipa Soares; Gonçalves, Pedro; Morais, Igor; Silva, Teresa; Matos, João Xavier; Albardeiro, Luís; Filipe, Augusto; Batista, Maria Joao; Santos, Sara; Fernandes, JoãoABSTRACT: 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 availability of key minerals. The supply risk associated with unpredicted geopolitical events needs to be eliminated/mitigated. Historical mine waste sites are the answer but evaluating mine waste is a lengthy and costly exercise. The study, undertaken in the Lousal Mine, used small unmanned aerial systems (sUASs) to model and determine mine waste volumes by generating orthomosaic maps with quick, inexpensive, and reliable results. Calculated mine waste volumes between 308,478 m3 and 322,455 m3 were obtained. XRD and p-XRF techniques determined the mineralogy and chemistry of waste, which varied from mineralization and host rocks with hydrothermal alteration and numerous neogenic sulphates (mostly gypsum, rhomboclase, ferricopiapite, coquimbite, and jarosite) related with supergene processes and weathering. The study shows the viability of using these sUASs to successfully model historical mine waste sites in an initial phase and for future monitoring programs.
- Áreas potenciais de Portugal para recursos minerais do domínio públicoPublication . Carvalho, Jorge; Filipe, Augusto; Lisboa, Jose; Xavier Matos, João Manuel; Batista, Maria Joao; Salgueiro, Rute; de Oliveira, Daniel Pipa Soares; Gonçalves, PedroRESUMO: O ordenamento do território é decisivo no processo de garantir o acesso aos recursos minerais. Durante os trabalhos para identificar as ações necessárias para a preparação da Estratégia Nacional para os Recursos Geológicos foi produzido um mapa de áreas potenciais em recursos minerais de Portugal. Constitui um ponto de partida para a implementação de uma metodologia vocacionada para a delimitação de áreas para a salvaguarda de recursos minerais.
