These are ion microprobe analyses of oxygen isotope ratios, grey scale values from confocal laser fluorescence images, and distance perpendicular to banding for analyses that were shown to be regular
Results of studying isotopic composition of helium in underground fluids of the Baikal-Mongolian region during the last quarter of XX century are summarized. Determinations of 3He/4He ratio in 139 sam
We performed incubation experiments with added nitrate (and additional sulfide or acetate) using water samples from the Lake Lugano North Basin, to determine the N and O isotope effects of nitrate red
Isotope dilution concentration determinations are accurate to approx. 1% for Rb and Sr, and 0.5% for Sm and Nd. Total procedural blanks averaged apporx. 1 ng for Sr and 100 pg...
A box model is presented to simulate changes in Mediterranean long-term average salinity and d18O over the past 20,000 years. Simulations are validated by comparison with observations. Sensitivity tes
