摘要:Based on the density functional theory (DFT), frequency shifts of garnet end-members upon isotope substitutions (18O/16O, as well as “non-traditional” stable isotopes) were calculated. According to the calculations, the temperature dependencies of fra...

摘要:Abstract(#br)The triple oxygen isotope compositions of phosphate grains in six martian meteorites have been measured by Secondary Ion Mass Spectrometry (SIMS) and combined together with their chlorine isotope and halogen concentrations have been used to constrain hydrosphere-li...

摘要:Abstract(#br)New planktonic and benthic foraminiferal stable isotope records from core YDY05 (northeastern Indian Ocean) provide new insights into paleoceanographic changes in the northeastern Indian Ocean since the last glacial period. The distinct δ 18 O decrease was observ...

摘要:... The δ 18 O of chert shows a robust quasi-linear increase through time - a signal that has been interpreted in a number of conflicting ways. For example, changing δ 18 O has been hypothesized to reflect the product of cooling surface ocean temperatures, a signature of evolv...

摘要:... Whereas δ 18 O has long been used for that purpose, triple oxygen isotopes (given as 17 O excess ) has only recently been analyzed in CaCO 3 . Carbonate 17 O excess is expected to reflect the temperature, in which the carbonate formed, and the triple oxygen isotopic compo...

摘要:Abstract(#br)Records of δ18O in stream flow are critical for understanding and modeling hydrological, ecological, biogeochemical and atmospheric processes. However, the number of such records are extremely limited globally and the length of such time series are u...

摘要:... Measured helium degassing from the rock and 18O-shift suggest that the co-seismic oxygen anomalies are directly related to volumetric strain changes. The findings provide a plausible physico-chemical basis to explain geochemical anomalies in water and may be use...

摘要:... We report a high resolution oxygen isotope18O) record of animal teeth-bone phosphates from an archaeological trench itself at Bhirrana, NW India, preserving all cultural levels of this civilization. Bhirrana was part of a high concentration of settlements alon...

摘要:Abstract(#br)The oxygen isotope effect of the ferromagnetic transition in itinerant ferromagnet strontium ruthenate SrRuO3 with a Curie temperature T c of 160 K is studied. We observed for the first time a shift of ∆ T c ~ 1 K by oxygen isotope...

摘要:Abstract(#br)Annual shell growth patterns of the three venerid bivalve species, Gafrarium pectinatum , Pitar citrinus , and Katelysia japonica were investigated based on the results of sclerochronological and stable oxygen isotope analyses of live-caught specimens from the i...
