To suggest consistent route toward planetesimal and planetary core formation in circumstellar discs we study gravitational instability outcomes in massive multiphase (gas-collisionless bodies) disc. Such unstable massive disc can be formed together with protostar in molecular cloud collapse with increased ratio of solids to gas density. In our calculations we found regimes when low-massive solid bodies subdisc drastically affect global structure formation in the disc, whose mass is constituted mainly by the gas. We demonstrated also that solitary areas of high gas density can concentrate solids, producing multiphase clumps, which can be considered as a cradle of large bodies formation
