... The metal abundance gradient in the disk of the Galaxy is found from stars with abundance determination from detailed analysis: d[Fe/H]/dR=(-0.05?0.01) kpc -1 . It is shown that the gradient can be explained by the fact that the disk is constituted of two metallicity groups of stars with an abundance jump between the groups. ...
