Capital Delta designates the distance of a sample from a reference fractionation line in a 3-isotope plot, e.g., from the terrestrial fractionation line. Multiple samples with the same capital delta then plot along a line parallel to a reference fractionation line – which, of course, then has the distance capital delta from the reference fractionation line.
