Collagen was extracted and analyzed for bulk stable isotopes of carbon-13 (δ 13 C) and nitrogen-15 (δ 15 N) and compound-specific isotopes of individual amino acids. Radiocarbon dating provided ...

The researchers conducted an analysis of the nitrogen and carbon isotopes bound to the tooth enamel of 43 fossilized teeth, all of which had been found in South Africa's Sterkfontein caves.

Probably each part will thus give rise to a chain of disintegrations. If one of the parts is an isotope of barium 5, the other will be krypton (Z = 92 − 56), which might decay through rubidium ...

The Boise State University Isotope Geology Laboratory (IGL) is a state-of-the-art geoanalytical facility for the analysis of trace elements and radiogenic isotopes in Earth materials, using both ...

This data set contains ice core chemistry, timescale, isotope, and temperature data analyzed by several investigators. In January 1998, the collaborative ice-drilling project between Russia, the ...
