The background database to this information window contains oxygen, carbon, nitrogen, and hydrogen isotopic compositions (also known as light stable isotopes) of bulk samples, compounds (e.g., clasts, chondrules and CAIs) and separates (mineral grains, density- and grain-size fractions fractions) of stones, stony-irons and iron meteorites. The typical delta values are displayed as calculated and published.
Most of C, N, and H isotope measurements have been done by the stepped-combustion or stepped-pyrolysis method. In this case, only the total C, N, and H abundances (yields) and their average isotopic compositions as released over the given temperature range are shown in this window.
