Cinnabar akin to that of HgO: each Hg center has two short Hg−S bonds (each 2.36 Å), and four longer contacts (with 3.10, 3.10, 3.30, and 3.30 Å separations). In addition, HgS is found in a black, non-cinnabar polymorph (metacinnabar) that has the zincblende structure. Cinnabar generally occurs as a vein-filling mineral associated with recent volcanic activity and alkaline hot springs. Cinnabar is deposited by epithermal ascending aqueous solutions (those near surface and not too hot) far removed from their igneous source. It is associated with native mercury, stibnite, realgar, pyrite, marcasite, opal, quartz, chalcedony, dolomite, calcite and barite. Cinnabar is
Ore Mountains 2007 the Ore Mountains and West Saxony is the most important Saxon holiday destination after the cities, and tourism is an important economic factor in the region. Since 2004 the Ore Mountain Tourist Association ("Tourismusverband Erzgebirge") has offered the Ore Mountain Card ("ErzgebirgsCard") with which over 100 museums, castles, heritage railways and other sights may be visited free of charge. The culture of the Ore Mountains was shaped mainly by mining that goes back to the Middle Ages. The old saying, coined here, that "everything comes from the mine" ("Alles kommt vom Bergwerk her!") refers to many areas of life
