pdf The depositional model of Lower Nutov section, Neptune field (north-eastern part of the Sakhalin shelf)
The article concerns the lithological study of the Lower Nutov (Upper Miocene) rocks penetrated by the Neptune’s field (North Sakhalin petroleum Province) discovery well. According to litho- and ichnofacies core samples analyses of the well Ayashsk-1, the depositional environment system of considered sequences was specified. The sedimentary scheme subscribes a partial facies description of a wave-dominated coast: from the transitional zone to the mid and lower shoreface. Most likely supposed environments are confined to the peripheral area of the Paleo-Amur Delta. The article emphasizes the analysis of the volcanic eruption impact on the formation of sedimentary strata, as well as to pyroclastic material distribution features.

Keywords: Lower Nutov Sub-Formation, depositional model, shallow-marine facies, volcaniclastic sedimentary rocks, Miocene, Paleo-Amur Delta, North Sakhalin petroleum Province.
