A mechanism is proposed for the inclusive production of eta mesons in hadron-hadron collisions on the basis of the idea of the production of a G(1590) meson/sup 4/ in the coalescence of the gluons of colliding hadrons. This meson decays primarily by channels containing eta mesons. The cross section for the inclusive production of eta mesons in pp and pp collisions is estimated and found to be given approximately by the expression sigma/sup incl//sub eta/ = 4.5(ln(s/M/sup 2//sub G/)-4.6) x 10/sup -28/ cm/sup 2/. At collider energies ((s)/sup 1/2/ = 540 GeV) the cross section would be sigma/sup incl//sub eta/ approx. =3.2 mb, so that the yield of eta mesons in pp collisions would be close to that observed experimentally.
