TY - BOOK AB - The variations in major elements and isotope composition (87Sr/86Sr, δ18O, δD) of interstitial waters in Leg 104 sediments is most probably caused by the alteration of volcanic matter. A reaction scheme where volcanic glass reacts with pore-water magnesium and potassium to form trioctahedral smectite, phillipsite, and chert is proposed. Model calculations demonstrate that the pore waters may evolve their negative δ18O signatures without recourse to unreasonably large amounts of volcanic detritus or external sources. -Authors AU - Aagaard,P AU - Egeberg,PK AU - Smalley,PC DO - 10.2973/odp.proc.sr.104.122.1989 PY - 1989/// TI - Diagenetic reactions in Leg 104 sediments inferred from isotope and major element chemistry of interstitial waters UR - http://dx.doi.org/10.2973/odp.proc.sr.104.122.1989 ER -
