From the results obtained with the tri-dimensional quantative classification method of Spite (1966), the relation age-abundance is analyzed for the Galaxy. The dispersion on the abundance for stars at a given age appears to prevail over a possible relation between the age and the abundance for these stars. From a detailed analysis of eight F2-G2 stars, it appears that the index Δm1 is sensitive to microturbulence velocity.
