In geochemistry, paleoclimatology, and paleoceanography δ13C (pronounced "delta c thirteen") is an isotopic signature, a measure of the ratio of the two...

signature of the SPICE event is a positive δ13C excursion, characterized by a 4 to 6 ‰ (per mille) shift in δ13C values within carbonate successions around...

An animal that eats food with high δ13C values will have a higher δ13C than one that eats food with lower δ13C values. The animal's own biochemical...

at any one time, δ18O and δ13C preserved in the fossil record can be affected by regional factors. Carboniferous δ18O and δ13C records show regional differences...

increases and δ13C values can be as low as −32‰. The δ13C value for animals depends on their diet. An animal that eats food with high δ13C values will have...

expressed in using delta notation of δ13C ("delta thirteen C"), which is reported in parts per thousand (per mille, ‰). δ13C is defined in relation to the Vienna...

87Sr/86Sr and δ13C. Continued erosion of the deeper levels of the Gondwanan mountain belts led to a peak in 87Sr/86Sr and linked positive δ13C and δ34S excursions...

photosynthetic pathway that produces δ13C values averaging about −12.5‰. It follows that eating these different plants will affect the δ13C values in the consumer's...

of the earliest examples of biological control. The δ13C of the emu's diet is reflected in the δ13C of the calcite of its egg shell. Small stones are swallowed...

sediment hydroxyarchaeol had very depleted δ13C at methane seeps. Both the methane and DIC present also had depleted δ13C values, but not as a perfect match to...
