Abstract
The correlation of allochthonous lithotectonic complexes of the Pacific allows to establish Early Jurassic (Sinemurian-Toarcian) anoxic event (J1-OAE) for time in the Asia-West Kamchatka region. This event is characterized by organic-riched black cherts and shales bearing pyrite that accumulated in the euxinic oceanic deep water basins of the Pacific. Later anoxic regime gradually weakened that was reflected in dominating of Midle-Upper Jurassic red gematite jaspers. J1-OAE in the Pacific was synchronous to global warming induced by planetary magmatic activity. Volcanic gases and hydroterms stimulated euxinic conditions in the deep water basins. The Sinemurian-Toarcian interval of the OAE in the Pacific Ocean is confirmed by data of the numerous World basins.
