Shades of orange sometimes misspelled as "vermillion". Also known as "cinnabar" and in its deeper form known as "China red", vermilion is reddish orange, much like scarlet, only more orange than scarlet. It can be produced naturally (from the mineral cinnabar) and artificially. Cinnabar is a deep red-orange mineral, mercuric sulfide, HgS; the principal ore of mercury; the pigment vermilion is extracted from this ore. The web color "tomato" is a medium reddish-orange color that is the color of actual supermarket tomatoes. Many vine-ripened tomatoes are a bit redder. The color of tomato soup is slightly less saturated. The color "tomato" is displayed
Volcanogenic massive sulfide ore deposit Volcanogenic massive sulfide ore deposit Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments. These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits. The density generally is 4500 kg/m. They are predominantly stratiform accumulations of sulfide minerals that precipitate from hydrothermal fluids on or below the seafloor in a wide range of ancient and modern geological settings. In modern oceans they are synonymous with sulfurous plumes called black smokers. They occur within environments
