A piston core collected from that mound comprises coarse clastic sulfide units interbedded with sulfidic muds. Hydrothermal minerals present in the 2.3 m section include pyrrhotite, pyrite, marcasite, sphalerite, chalcopyrite, iss (intermediate solid solution in the Cu-Fe-Zn-S system), chalcopyrrhotite, galena, talc, barite, and amorphous silica. Mineral fabrics of the clasts indicate that the material was precipitated at or near the sea floor by mixing of hot hydrothermal fluids with cold seawater. Rapid sedimentation in a rift valley is clearly conducive to the formation of large hydrothermal mineral deposits like those believed to be present within and beneath these mounds. No reliable estimate of the bulk composition of the mounds can be made with existing data, but their size is comparable to major hydrothermal mineral deposits found on land.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Massive sulfides in a sedimented rift valley, northern Juan de Fuca Ridge","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-17 01:32:10.787151","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1987,"MonPub":null,"DateUpdate":"2020-10-16","DateCreate":"2005-11-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1987G787100005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0012-821X(87)90106-3"},"refs":null,"anarec":{"AnaID":78050,"PubliDate":1987,"Pagination":"49-61","XtraPublOfAnaID":null,"ISBN":null,"Volume":"82","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42615,"SerRR":"Earth and Planetary Science Letters.
