We consider the hadronic production of heavy-quark bound states (QQ-bar) and also associated production of paris of hadron containing heavy quarks (Q-barq + q-barQ). Calculations of total cross sections and of x/sub F/ spectra are presented for both the J/psi and UPSILON. Processes involving fusion of quarks as well as amalgamation of gluons from the beam and target hadrons are important, but in both cases the production of J/sup P/C = 1/sup - -/ bound states proceeds mainly via P-wave intermediate states. Processes involving gluons from the initial hadrons dominate at high energies for all beams and targets, and at all energies for proton and K/sup +/ beams where quark fusion cannot proceed using only valence quarks.
