An Interactive WebGIS Integrating Environmental Susceptibility Mapping in a Sel...
Lia Duarte; Ana Teodoro; Santos, P; de Almeida, CR; Cardoso-Fernandes, J; Flores, DMining activities promote resulting wastes, so coal mines are prone to release contaminants to the environment, namely to the soil and water. Therefore, the analysis of this type of risk is crucial in waste pile management. The Sao Pedro da Cova (Porto, Portugal) coal waste pile has been studied in recent years, with several data acquired from 2019-2021 under a research project using distinct methodologies. The...

Os fósseis vegetais e a génese do carvão: Uma visita de estudo à bacia carboníf...
Calafate, L; Oliveira, A; Flores, D; Moreira, JRThis work shows an experience under Supervised Teaching Practice (PES), which aims to conduct a field trip to the Carboniferous Douro Basin according to the Nir Orion model. Addressing the plant fossils and the genesis of coal, we intend to investigate if the field trips, organized according to the proposed model, contribute to the apprenticeship of Biology and Geology by the students. The case study was the re...

Burning of coal waste piles from Douro Coalfield (Portugal): Petrological, geoc...
Ribeiro, J; Ferreira F da Silva; Flores, DIn the Douro Coalfield anthracites were exploited for decades (1795-1994). Besides many small mines Douro Coalfield had two principal mining areas (S. Pedro da Cova and Pejao). Coal mining activities cause several impacts on the environment, one of which is the amount of discard or waste which was disposed of all over Douro Coalfield resulting in one of the most significant and severe impacts on the environment...
The Bucaco Basin (Portugal): Organic petrology and geochemistry study
Flores, D; Gama Pereira, LCG; Ribeiro, J; Pina, B; Marques, MM; Ribeiro, MA; Bobos, I; Pinto P de JesusThe Bucaco Basin includes a Carboniferous/Permian sequence that comprises, from bottom to top, the following stratigraphic sequence: Algeriz Formation, Vale da Mo Formation and Monsarros Formation. Algeriz Formation is constituted by deposits of basal breccia with variable thickness and alternating layers of siltstone, mudstone and conglomerate. Vale da Mo Formation corresponds to lacustrine deposits comprising...
Petrographic, mineralogical and geochemical characterization of the Serrinha co...
Ribeiro, J; Ferreira da Silva, EF; Li, Z; Ward, C; Flores, DSerrinha is the largest coal waste pile resulting from mining activities in the Douro Coalfield, Portugal. The exploitation of anthracite in tens of small mines caused some environmental impacts, as is the case of the coal waste piles that exist in old mines and adjacent areas. The Serrinha waste pile is essentially made up of 2 million tonnes of shales and carbonaceous shales, deposited in a topographical depr...
