A mercury mine started before 1850. Owned by Minas de Almadén.
Volcano-sedimentary Hg ores hosted in quartzite and volcanic rocks.
Almadén is the largest mercury deposit in the world, having produced more than 8 million recorded flasks of mercury (250,000 metric tons; 1 flask = 76 lb) from a volume of ore of approximately 450 X 600 X 50 m3. It has produced about 1/3 of the world's mercury.
The name Almadén stems from the Arabic "al-ma 'daniy 'yun", "the mine" or "the mineral".
The volcanosedimentary rocks range from Lower Ordovician to Upper Devonian in age. Hall et al. (1997) suggest the Hg mineralization was active between 427-360 Ma, based on Ar/Ar determinations on illite and biotite, but Higueras et al. (2000) obtained a Rb-Sr isochron of 365±17 Ma on mineralized basic volcanic rocks.
