The dicotyledonous C-4 species had relative greater mean delta C-13 value and less total carbon content than both monocotyledonous C-4 and C-3 Species. Most dicotyledonous C-4 species were annual forbs and halophytes. Some C-4 species had been previously documented, but their delta C-13 ...
Carbon stable-isotope variation through the Cenomanian–Santonian stages is characterized using data for 1769 bulk pelagic carbonate samples collected from seven Chalk successions in England. The sections show consistent stratigraphic trends and δ13C values that provide a basis for highresolution correlati...
The isotopic carbon ratio of a calcite-precipitating solution flowing as a water film on the surface of a stalagmite is determined by Rayleigh distillation. It can be calculated, when the HCO3--concentration of the solution at each surface point of the stalagmite and the fractionation factors are...
沉积学报990224 Computation in this article shows that a complete reverse carbon isotopic distri bution be produced by the mixture of two kinds of biogenic gas with a normal carbon isotopic distribution (i.e. δ 13 C m ethane <δ 13 C ethane <δ 13 propane <δ 13 C n-butane). While a...
Stable isotope composition of organic carbon (δ13C) was measured on the bulk soil samples using isotope-ratio mass spectrometry (IRMS), following the USGS method76. Briefly, all samples were homogenized by grinding with a mortar and pestle. They were then decarbonated (soils) with HCl (3 ...
A Dual-Carbon-and-Nitrogen Stable Isotope Ratio Model Is Not Superior to a Single-Carbon Stable Isotope Ratio Model for Predicting Added Sugar Intake in So... An objective measure of added sugar (AS) and sugar-sweetened beverage (SSB) intake is needed. The δ(13)C value of finger-stick ...
