摘要:... In this study, stable isotopes (δD and δ 18 O), 222 Rn measurements, and corresponding models ( 222 Rn and 18 O mass balance models) were employed to evaluate the groundwater discharge and associated chemical inputs to Poyang Lake. The results showed that the distributio...

摘要:... In this paper we summarized the spatial distribution and the controlling factors of δ D, δ 18 O, d-excess and 17 O-excess in Antarctic snow and ice, and discussed their reliability and applicability as palaeoclimate proxies. Recent progress in the stable isotopic recor...

摘要:Abstract(#br)This paper aims to achieve an improved understanding of the long-term change trends of precipitation δD and δ 18 O values (δD p and δ 18 O p ) in the Asian monsoonal region and their relationship with the corresponding humidity trends during the Holocene. To...

摘要:Abstract(#br) 87 Sr/ 86 Sr, δD and δ 18 O together with chemistry of oilfield brines, were measured from Cambrian to Neogene strata in the Kuqa Foreland Basin, northwest China. The brines have 87 Sr/ 86 Sr ratios ranging from 0.70944 to 0.71716, δD values from −33‰ t...

摘要:Abstract(#br)The repeatability, reproducibility and accuracy of the direct measurement of δ (D) and δ ( 18 O) isotopes in water samples were evaluated using Cavity Ring-Down Spectrometry, and values comparable with the Isotopic Ratio Mass Spectrometry were obtained. Memory...

摘要:Abstract(#br)The stable isotope compositions ( δ 18 O and δ D) of water have been used to determine the relative contributions of different water sources to the groundwater in a barrier sand-bar that separates a coastal freshwater marsh from Lake Erie, Canada. An extensive ...

摘要:... Trends in δD and δ 18 O of leaf cellulose were examined for three species growing across climatic gradients caused by elevation and slope aspect in southeastern Utah, USA. The species differed in morphology ( Pinus edulis vs. Yucca glauca ), photosynthetic pathway (C 3 Y. ...

摘要:... In the case of a null wind velocity, slopes of δ D –δ 18 O trajectories of residual waters hyperbolically decrease with increasing water temperatures in the range 23–47 °C. For wind velocities ranging from 0.8 to 2.2 m s −1 , slopes of the δ D –δ 18 O trajector...

摘要:Abstract(#br)Paired D/H and 18 O/ 16 O analyses of natural goethites range from −224‰ to −93‰ for δD and from −15.5‰ to +2.8‰ for δ 18 O. The isotopic systematics of these goethites seem to be most closely mimicked by the goethite–water D/H and 18 O/ 16 O frac...

摘要:Abstract(#br)The edifices of many active volcanoes on the Kuril Islands contain hydrothermal systems whose surface manifestations include springs with diversity in their chemical compositions and in their physical and chemical parameters. Thermal waters of Kuril Islands were...
