Abstract
The old mining site in the Azogue Valley (Almeria, Spain) was exploited in the 19th century for mercury and antimony. This mineralisation is hosted in metamorphosed Permo-Triassic rocks and shows no spatial relationship with regional volcanism. The metallogenetic characteristics suggest the presence of an epithermal deposit as much as 1 km in length, with high Hg and Sb values. These values, together with high Ag, Au, As and Ba contents, suggest similarities to `hot spring'-type epithermal mineralisation. An Hg vapour and soil survey yielded Hg haloes which identified the old mining zone, outlining the exploited veins and marking enrichment zones at fault–vein intersections. The geochemistry of Hg-vapour was particularly successful in delineating the epithermal deposit.
