The Bureya sedimentary basin, which is located in southeastern Russia, extends north-northeasterly for 230 km. The basin, commonly ∼65 km wide, contains thick sections of Mesozoic strata that record important tectonic and eustatic changes at the edge of the East Asian continental margin. It initially developed within the passive early Mesozoic continental margin. Later, during the Late Jurassic, the basin again was strongly affected by extension. Based on up-to-date geological and geophysical data, a sequence stratigraphic model consisting of six megasequences and several sequences was constructed. Sedimentation rates, some of which are remarkably high, were calculated for each sequence. The principal evolution stages of the Bureya Basin of compound (hybrid) type are as follows: (1) During Late Triassic to Middle Jurassic, the basin formed on the passive continental margin with edge submeridional rifts. The sedimentation was influenced by erosion of an active continental margin. (2) During the Late Jurassic through Cretaceous, it was an intracontinental, NE-trending, pull-apart basin.
