pdf  Oil and gas formation in the Aldan-Maya basin (Eastern Siberia)
The basic features of the structure of the Aldan-Maya basin represented by the Riphean, Vendian and Cambrian deposits are analized. The upper subformation of Malka Formation of R2, Ignikan Formation (upper part of a Lokhandin series) of R3, and Inikan Formation of C1-2 are considered as petroleum source rocks. The scale of primary hydrocarbons migration and their possibly large losses due to complex geological structure of the region and repeated erosional events were counted on the basis of mapping of petroleum source deposits and calculated genetic evolution models of VNIGRI.

Keywords: petroleum source formation, primary migration, migration hydrocarbons, Aldan- Maya basin.
