The 3550 year BP-1944 A.D.magma-plumbing system of Somma-Vesuvius: constraints on its behaviour and present state through a review of Sr-Nd isotope data
Somma-Vesuvius magma chamber crustal contamination
2015/9/15
Vesuvius, dominating the densely-populated Neapolitan area, is one of the most dangerous volcanoes in the World. Its destructive power derives from energetic subplinian and plinian eruptions, such as ...
Dissolved organic carbon and its carbon isotope compositions in hill slope soils of the karst area of southwest China: Implications for carbon dynamics in limestone soil
karst slope land soil organic carbon dissolved organic carbon δ13C
2017/4/11
Dissolved organic carbon (DOC) can be considered fine indicators of soil quality that influence soil function in specific
ways and are very sensitive to changes in soil management practices. In this ...
Oxygen three-isotope ratios of silicate reference materials determined by direct comparison with VSMOW-oxygen
oxygen three-isotope ratios silicate reference materials VSMOW-SLAP normalization terrestrial fractionation line BrF5 fluorination
2017/8/10
The δ17O and δ18O values of some international silicate reference materials such as NBS-28 quartz, NBS-30 biotite, UWG2 garnet, San Carlos olivine and some mineral separates of terrestrial origin were...
Argon isotope ratio of the plume-source deduced from high-resolution stepwise crushing extraction
3He/4He 40Ar/36Ar noble gases Loihi mantle plume
2017/8/10
We have carried out noble gas analysis for gases released by a high-resolution stepwise crushing on basaltic glass and olivine separated from a new set of pillow basalts collected form the Loihi seamo...
A normalised seawater strontium isotope curve: possible implications for Neoproterozoic-Cambrian weathering rates and the further oxygenation of the Earth
Neoproterozoic-Cambrian weathering rates the further oxygenation
2010/9/28
The strontium isotope composition of seawater is strongly influenced on geological time scales by changes in the rates of continental weathering relative to ocean crust alteration. However, the potent...
Stable isotope compositions of a late Jurassic ammonite shell: a record of seasonal surface water temperatures in the southern hemisphere?
Stable isotope compositions late Jurassic ammonite shell seasonal surface water temperatures
2010/9/28
Exceptional preservation of aragonite secreted by ammonites offers an opportunity to determine the seasonal temperature variations of Mesozoic surface waters. Ontogenetic profiles of carbon and oxygen...
