We model the nucleosynthesis in black hole accretion disks (and it’s neighboring region) at the base of a gamma ray burst. The result is abundant production of light isotopes, as well as heavier elements with mass numbers in the range A∼60-80, which corresponds to the first maximum of nuclide production in the process of rapid neutron capture (r-process). Isotopes are created mainly on the surface of an accretion disk and in the area beyond it, where they are carried by the magnetized, neutrino-driven wind.
