We estimated iron and metallicity gradients in the radial and verticaldirections with the F and G type dwarfs taken from the RAVE DR4 database. Thesample defined by the constraints Zmax<=825 pc and ep<=0.10 consists of starswith metal abundances and space velocity components agreeable with thethin-disc stars. The radial iron and metallicity gradients estimated for thevertical distance intervals 0<Zmax<=500 and 500<Zmax<=800 pc ared[Fe/H]/dRm=-0.083(0.030) and d[Fe/H]/dRm=-0.048(0.037 )dex/kpc; andd[M/H]/dRm=-0.063(0.011) and d[M/H]/dRm=-0.028(0.057) dex/kpc, respectively,where Rm is the mean Galactocentric distance. The iron and metallicitygradients for less number of stars at further vertical distances,800<Zmax<=1500 pc, are mostly positive. Compatible iron and metallicitygradients could be estimated with guiding radius (Rg) for the same verticaldistance intervals 0<Zmax<=500 and 500<Zmax<=800 pc, i.e.d[Fe/H]/dRg=-0.083(0.030) and d[Fe/H]/dRg=-0.065(0.039) dex/kpc;d[M/H]/dRg=-0.062(0.018) and d[M/H]/dRg=-0.055(0.045) dex/kpc. F and G typedwarfs on elongated orbits show a complicated radial iron and metallicitygradient distribution in different vertical distance intervals. Significantradial iron and metallicity gradients could be derived neither for thesub-sample stars with Rm<=8 kpc, nor for the ones at larger distances, Rm>8kpc. The range of the iron and metallicity abundance for the F and G typedwarfs on elongated orbits, [-0.13, -0.01), is similar to the thin-disc stars,while at least half of their space velocity components agree better with thoseof the thick-disc stars. The vertical iron gradients estimated for the F and Gtype dwarfs on circular orbits are d[Fe/H]/dZmax=-0.176(0.039) dex/kpc andd[Fe/H]/dZmax=-0.119(0.036) dex/kpc for the intervals Zmax<= 825 and Zmax<=1500pc, respectively.
