2017/4/12
Basalts from Logudoro, Sardinia (Italy), showing geochemical features similar to EM1-type mantle source, have been
analyzed for their Li isotopic composition to provide data related to a heretofore u...

2017/8/9
Several processes may contribute to systematic downcore trends in δ13C of bulk Sphagnum peat. Whereas changes in water availability during C assimilation may change δ13C values in both a negative and ...
Possible precursor of perylene in sediments of Lake Biwa elucidated by stable carbon isotope composition
Lake Biwa perylene stable carbon isotopic composition sediment
font style='font-size:12px;'>
2017/8/9
We determined the stable carbon isotope compositions (δ13C values) of perylene and compounds coexisting with it to elucidate the precursor of perylene in sediments of Lake Biwa. Although we found a hi...
Groundwaters of Mt. Vulture volcano, southern Italy: Chemistry and sulfur isotope composition of dissolved sulfate

2017/8/9
We report the chemical composition of groundwaters—including the first data on the sulfur isotopic composition of dissolved sulfate—from the volcanic aquifers of Mt. Vulture, one of the most important...
Experimental Alteration of Volcanic Tuff: Smectite Formation and Effect on 18O Isotope Composition
Alteration Mechanism of Volcanic Tuff Oxygen Isotope Exchange Smectite Tuff
font style='font-size:12px;'>
2011/12/8
Abstract: Three samples of volcanic tuff were hydrothermally altered at ∼82°C in a soxhlet apparatus for periods from 745 to 2706 h. The samples correspond to partially altered specimens of volc...
