age-metallicity relation

(AMR)
(older stars generally have lower metallicity)

The age-metallicity relation (AMR) is a reverse correlation between the age of stars their metallicity within the local Milky Way. These also have a correlation with velocity dispersion, thus, a age-velocity-metallicity relation (AVMR). Such an AMR is consistent with the fact that as time passes, supernovae increase the metallicity of molecular clouds that are star forming. These also affect other aspects of their abundances.
