Integrating multispectral satellite data and geomorphology for secondary iron mineral mapping in the Sierra Minera de Cartagena-La Unión (SE Spain)
The Sierra Minera de Cartagena-La Unión (SE Spain) is a historical mining district where acid mine drainage (AMD) continues to impact soils and water resources. This study, on the one hand, maps three of the secondary iron minerals linked to AMD processes—hematite, goethite, and jarosite—using Sentinel-2 multispectral...
