euxinic Applied to an environment in which the circulation of water is restricted, leading to reduced oxygen levels or anaerobic conditions in the water. Such conditions may develop in swamps, barred basins, stratified lakes, and fjords. Euxinic sediments are those deposited in such conditions, and are usually black and organic-rich. Compare ANOXIC.
