Hydrogen Isotope Composition of Pore Waters and Interlayer Water in Sediments from the Central Western Pacific, Leg 129

“…δD of smectite hydroxyl water from Samples 129-800A-37R-2,0-10 cm, and 129-800A-49R-2, 140-150 cm, are -48.9‰ and -53.6%c respectively (Table 2), and OH-pore-water fractionations are -43.0 and -46.1. These values correspond to isotopic temperatures of 15°C and 3°C ± 15°, respectively, if one applies the empirical smectite-water fractionation curve of Yeh (1980). If the errors are taken into account, these temperatures are consistent with estimated present temperatures of 13°C and 17°C, respectively (Fisher, pers, comm., 1991).…”

Illite occurrences related to volcanic-hosted hydrothermal mineralization in the Biga Peninsula, NW Turkey: Implications for the age and origin of fluids

“…12). Modelling this water as it evolved to higher temperature, using the equation of Yeh (1980), intersects the measured D and  18 O values of the illites from Koru and Kumarlar. The temperature of the water in equilibrium with the illites from both deposits corresponds closely to the high temperature fluid inclusions homogenization temperatures (Fig.…”

“…δ 18 O ve δD diyagramında, artan sıcaklıkla birlikte suyun izotopsal değişimine göre; I-S'leri oluşturan suyun izotopsal bileşimi deniz suyu bileşiminden uzak, Doğu Akdeniz Meteorik Su (DAMS, Gat vd., 1996) bileşimi ile magmatik su bileşimi arasında yer almaktadır. Sıcaklıkla birlikte değişen illitsu dengesinin belirlenmesinde oksijen için R3 I-S (% 90 I, % 10 S) için Savin ve Lee (1988) eşitliği, hidrojen için ise Yeh (1980) …”
