Students & professors of NMTM visit world-class deposits in southern Spain

 

A group of 14 undergraduate and graduate students and faculty from the Millenium Nucleus in Metal Tracers participated in an eight day field trip to Spain, aiming to introduce students to ore deposit that are not available in Chile. The field trip included visits to the Rio Tinto VMS deposit, the Ronda peridotite massif and the world-class Almaden Hg deposit.

Rio Tinto Mine

Rio Tinto is the largest deposit in the Devonian Iberian Pyrite Belt (IPB). The IPB contains over 100 VMS deposits with over 10 giant (world-class) deposits with more than 50 Mt of ore. Mineralization includes massive sulfides with pyrite, chalcopyrite, sphalerite, and galena.

Ronda Peridotite Massif

The Ronda massif is considered the world´s largest outcrop of orogenic lherzolites. It represents a slice of Proterozoic subcontinental lithospheric mantle which was exhumated during the Miocene extension and emplaced onto continental crust. It also hosts graphite, Fe-Ni-Cu-sulfides, and chromite deposits.

Almadén Mine

Almadén is the largest mercury deposit in the world. Cinnabar (HgS) is hosted and associated with Lower Silurian quartzites, cross-cut by a diatreme body of basaltic composition.
