Mercuryville, California become a ghost town. One of the last remaining large mine buildings was burned in wildfires in the mid-1970s, although some concrete structures and metalwork from the mines remain. Mercuryville, California Mercuryville, California is a ghost town in the Mayacamas Mountains along The Geysers road. Mercuryville was founded in 1874, after cinnabar, a mercury bearing ore, was discovered in eastern Sonoma County around 1870. Mercury is a dense liquid metal that can be used to separate gold from other less dense materials and the California Gold Rush, which had begun only 20 years earlier, increased the demand and price of
Ore genesis and loses its metal carrying capacity. Ore deposits rarely fit neatly into the categories in which geologists wish to place them. Many may be formed by one or more of the basic genesis processes above, creating ambiguous classifications and much argument and conjecture. Often ore deposits are classified after examples of their type, for instance Broken Hill type lead-zinc-silver deposits or Carlin–type gold deposits. Classification of hydrothermal ore deposits is also achieved by classifying according to the temperature of formation, which roughly also correlates with particular mineralising fluids, mineral associations and structural styles.
