In the Asian paleoocean understood ore structures set in Sayano-Tuva marginal sea (in deep-sea depresion and rift, cutting continental slope). Ore-hosted deposits are Vend - Early Cambrian. In the Urals paleoocean, there were Sakmar marginal sea, inter-arc and back-arc basins. Ore-hosted deposits are mainly Middle Devonian. Ore deposits had been formed under spreding (back-arc and inter-arc basins), local spredings and shifts (inside-arc conditions). Their composition had been depended of ore-hosted complexes composition and features of hydroterms. Temperature of ore-forming varied from 80 to 270 °C, rarely up to 460 °C; pressure - 330-710 B. In some Urals deposite hydrocarbons and thread bacteria are established. In the paper, data about isotop composition of S, C, O, and Pb are given.
