Giacimento di mercurio di Vallalta-Sagrón (Giacimento di cinabro di Vallalta-Sagrón), Dolomiti, Italia


Cinnabar deposit exploited by two contiguous mines: the main Vallalta mine (Gosaldo, Belluno Province, Veneto) and Sagrón mine (Sagron Mis, Trento autonomous province, Trentino-Alto Adige/Südtirol [(County of Tyrol, Austrian Empire until 1867 and Austro-Hungarian Empire from 1867 to 1918]), located on the right and left sides of Pezzea stream, respectively.

The ore body consists of main cinnabar, with subordinate/minor mercury, metacinnabar, pyrite, and marcasite. It is located along a fault system (Todros, Schilling and Block faults) subparallel to the Valsugana Thrust, the main structure of the Eastern Southern Alps extending 100 km from Trento to Cadore, at the contact of Permian ignimbrites with slices of the Variscan metamorphic basement.

Cinnabar crystals are very rare. Cinnabar usually appears as fine pure grains with vermillion colour and metallic lustre (the old miners called this variety "Stahlerz", i.e., steel ore), very fine pure grains with purplish-red colour and metallic lustre (the old miners called this variety "Lebererz", i.e., liver ore), and earthy brick-red masses, containing mica, quartz and gypsum as impurities (the old miners called this variety "Ziegelerz", i.e., brick ore). Cinnabar is tipically associated with calcite, and sometimes with baryte, quartz, gypsum, and chlorite. Mercury droplets have been found on cinnabar and very rarely on gypsum.
