(Corta Manuel-Mercedes, Minas de Cala, Cala, Huelva, Andalucia, Espana)
From a geological point of view, the deposit of the Cala Mine is located in the south flank of the (antiform) Olivenza-Monesterio, inside of the zone Ossa-Morena. In this area, Palaeozoic rocks were affected by Hercynian tectonics. The granitic intrusions were accompanied by contact metamorphism (skarn formation) with important deposits of magnetite.
Cala is included in Sierra de Aracena range, a part of Sierra Morena range.
