Mercury in Mid-Ocean ridges (on the example of Mid-Atlantic ridge and East Pacific rise)

Marine Biogeochemical Cycling of Mercury

“…Hg is found in abundance in metalliferous deposits associated with subaerial and submarine volcanism. ,− Its chalcophilic (sulfur-loving) nature results in accumulation of Hg (as cinnabar and metacinnabar) in chalcopyrite, sphalerite, and other sulfide minerals in oceanic hydrothermal systems. Additionally, Hg has been observed in nascent elemental form as liquid metal droplets at locations of active hydrothermal venting .…”
