Maia, M., Moreira, N., Vicente, S. et al. The Mociços Cu-deposit is part of a cluster of ancient copper mines in the Sousel-Barrancos metallogenic belt in the Ossa-Morena Zone at the SW Iberia. The orebodies develop along NNW-SSE quartz-carbonate-sulfides veins with pyrite and chalcopyrite as the main sulfide phases, and ore emplacement has been attributed to […]

Crofts, Roger; Gordon, J. E. (John E.); Brilha, José; Gray, Murray; Gunn, John; Larwood, Jonathan; Santucci, Vincent L.; Tormey, Daniel; Worboys, Graeme L.; Groves, Craig These Guidelines are intended to help improve the conservation and management of geoheritage and geodiversity in protected and conserved areas and recognition of the interrelationships and interactions with biological features and […]
How a mesoscale cyclonic vortex over Sahara leads to a dust outbreak in South-western Iberia
Couto FT, Cardoso EHC, Costa MJ, Salgado R, Guerrero-Rascado JL, Salgueiro V (2021) The study focused on an exceptional desert dust outbreak episode, in particular on the role of atmospheric circulation transporting high amounts of dust toward Portugal in February 2017. In order to assess the atmospheric conditions behind the mineral dust layer observed in […]
Guidance for the Integrated Use of Hydrological, Geochemical, and Isotopic Tools in Mining Operations
Wolkersdorfer, C., Nordstrom, D.K., Beckie, R.D. et al. This paper summarizes international state-of-the-art applications and opportunities for employing and deploying hydrological, geochemical, and isotopic tools in an integrated manner for investigations of mining operations. It is intended to aid formulation of more integrated approaches for evaluating the overall sustainability of mining projects. The focus is particularly […]
Design of a Multipoint Cost-Effective Optical Instrument for Continuous In-Situ Monitoring of Turbidity and Sediment
Matos, T.; Faria, C.L.; Martins, M.S.; Henriques, R.; Gomes, P.A.; Goncalves, L.M. A cost-effective optical instrument for continuous in-situ monitoring applications is presented. With a production cost in raw materials of 38 €, a power consumption of 300 A in sleep mode and 100 mA in active mode (5 ms reading), and a capacity to […]
A Discussion on the Quantification and Classification of Geodiversity Indices Based on GIS Methodological Tests
Gonçalves, J., Mansur, K., Santos, D. et al. Quantitative assessment methods are attaining special attention in geodiversity research. Procedures to map geodiversity indices have been proposed by several authors though there is no consensus on how to best apply and replicate them in diverse areas. A contribution to the quantitative mapping of geodiversity using GIS tools […]
