Finely laminated and undisturbed except in the area of southwest basin; this part, bedding, resedimentation, brecciation are common. In addition, some sediment cores contain vein minerals precipitated open fissures which crosscut unlithified metalliferous sediments. These veins conduits by new hot brine vents into Deep. Vein mineralogy is dominated anhydrite, talc, smectite, pyrite, sphalerite, chalcopyrite. Vertical zonation due to cooling reaction incoming as it rises through sediment. Near Southwest Basin- west basin transition, has been locally recrystallized a hematite-magnetite-pyroxene assemblage, probably intrusion basalt sediments.--Modified journal abstract.
