Sentence examples for limestone carbon from inspiring English sources

Isotopic signatures are expressed in δ notation as ratios relative to PeeDee limestone (carbon) and the atmospheric N2 (nitrogen) standards as follows: δX = 1000(Rsample - Rstandard/Rstandard) Where X is C or N and R is the corresponding ratio C/C or N/N.

Isotopic signatures are expressed in delta notation as ratios relative to PeeDee limestone (carbon) and atmospheric N2 (nitrogen) standards as follows: δX = [(R sample/R standard) - 1] * 1000, where X is C or N, and R is the corresponding ratio C/C or N/N.
