... For a semple of red giants comprising about 2000 stars, the distributions of metallicity [Fe/H] are given. ... The center of the distributions of giants in both galactic poles is found to demonstate a statisticaly significant gap similar to the one found earlier for the late main-sequence stars. The implications of the metallicity distribution properties for the problems of the chemical evolution of the galactic disk are discussed. ...
