Methodological approach for mineralogical characterization of tailings from a Cu(Au,Ag) skarn type deposit using QEMSCAN (Quantitative Evaluation of Minerals by Scanning Electron Microscopy)
K.Guanira, T.M.Valente, C.A.Ríos, O.M.Castellanos, L.Salazar, D.Lattanzi, P. Jaime Methodological approach for mineralogical characterization of tailings from a Cu(Au,Ag) skarn type deposit using QEMSCAN (Quantitative Evaluation of Minerals by Scanning Electron Microscopy) Skarn type deposits are important potential resources for Cu, Au, and Ag as well as other strategic metals, which require accurate characterization of the […]
Photosynthetic pigments in acid mine drainage: Seasonal patterns and associations with stressful abiotic characteristics
Patrícia Gomes, Teresa Valente, Dulce Geraldo, Catarina Ribeiro Photosynthetic pigments in acid mine drainage: Seasonal patterns and associations with stressful abiotic characteristics Acid mine drainage represents an extreme type of water pollution. The environments develop especial hydrochemical and ecological characteristics, such as high concentrations of acidity and low biodiversity, with dominance of acidophilic organisms. Ecological criteria are […]
Predicting ore content throughout a machine learning procedure – An Sn-W enrichment case study
C.Iglesias, I.M.H.R.Antunes, M.T.D.Albuquerque, J.Martínez, J.Taboada Predicting ore content throughout a machine learning procedure – An Sn-W enrichment case study The distribution patterns of trace elements are very useful for predicting mineral deposits occurrence. Machine learning techniques were used for the computation of adequate models in trace elements’ prediction. The main subject of this research is the definition of […]

Prasinophyte bloom and putative fungi abundance near the Kačák event (Middle Devonian) from the Odivelas Limestone, Southwest Iberia
Gil Machado, Ladislav Slavík, Noel Moreira, Paulo Emanuel Fonseca Prasinophyte bloom and putative fungi abundance near the Kačák event (Middle Devonian) from the Odivelas Limestone, Southwest Iberia The Kačák Event is one of the several prominent Devonian climatic and biotic perturbations with a supra-regional to global extent. Its record can be traced in the litho- and biostratigraphy of uppermost Eifelian-lowermost […]
