Sandstone-hosted stratabound copper deposits of the south Pyrenean foreland basin

This project concerns the nature and timing of sandstone-hosted copper mineralization located in the South Pyrenean thrust-belt/foreland basin system. The host rocks were deposited in the Jaca basin and in the Ebro basin, both belonging to the Pyrenean foreland basin that was developed during the Oligocene in response to the oblique collision between the Iberian microplate and Europe. A chain of hills called “External Sierras”, which represents one of the youngest structures in the Pyrenees resulting from the emergence of a large thrust sheet, separates the latter basins.
Making decisions on industrial water sources: the case of Zaragoza, Spain
Published in Urban Water Journal, 2020

Focusing on Spain, Zaragoza is a city located along the banks of the river Ebro. As Lutz and Merz (2016) indicate, water resources in the River Ebro Basin are currently under pressure due to several factors such as industrial activities, agriculture or urban water abstraction. Additionally, several climate studies point out that the Ebro River Basin has become hotter and drier (Bovolo et al. 2010), with longer and more intense drought episodes (Bovolo et al. 2010). Under these water scarcity conditions, climate change can amplify the impact of these factors in terms of quantity and quality (Bovolo et al. 2010; Lutz and Merz 2016; Omedas, Galván, and Gómez 2011). Moreover, the Ebro River Basin, with 108 big dams, is one of the most regulated river basins in Europe, so the ability to manage growing water demands by building new infrastructures is very limited (Omedas, Galván, and Gómez 2011).
