As long as there is no isotopic fractionation
of Sr during barite precipitation, Sr derived from seawater or from the dissolution of normal marine carbonate host rocks would have a marine isotopic signature (Hanor 2000).
The stable isotope ratios of individual elements are affected by two main factors, namely isotopic fractionation
and radioactive decay.
We considered an isotopic fractionation
across trophic levels of 3.
Stable carbon and nitrogen isotopic fractionation
between diet and tissue of captive red fox: implications for dietary reconstruction.
Among the topics are instrumental isotopic fractionation
, measurement strategies, chemical imaging, inductively coupled plasma mass spectroscopy, thermal ionization mass spectrometry, secondary ion mass spectroscopy, and gas source isotope ratio mass spectrometry for analyzing noble gases.
of carbon/nitrogen of Mycenas and plants at field sites can reveal the mushroomA[sup.
These factors affect the determination of the extent of isotopic fractionation
and, consequently, the isotopic variability of the organisms.
j] represents the intrinsic isotopic fractionation
at the microbial process level.
The fingerprint is the result of a natural phenomenon called isotopic fractionation
, in which different isotopes of mercury react to form new compounds at slightly different rates.
This isotopic fractionation
can be described by a fractionation factor, which is characteristic for the process:
For example, greater isotopic fractionation
Because isotopic fractionation
in plant shoots can vary according to rhizobial strain and host cultivar (Ledgard, 1989), a separate [delta][sup.
