Abstract

This article presents a methodology for mapping anthropogenic materials. This is applied to an area affected by mining and industrial activities. The Sierra de Cartagena–La Unión (SE Spain), a 2,500-year-old mining district extending over an area of 100 km2. The anthropogenic cartography illustrates the existence of 12 open-pits, 1,902 mining wells, 2,351 waste depo- sits, including 89 tailing dams and waste rock derived from mining processes. Mine wastes occupy an area of 9 km2 and have an approximate volume of 200 Mm3. Mineralogical, physical and chemical data distinguish nine different types of mine and metallurgical wastes: open pit spoils, post-flotation wastes, gravity concentration spoils, gossan, molten slag, pre-concentra- tion wastes, mine spoils, well borings, post-flotation sludge in Portman and Gorguel Bay.
