N2 - In the Late Devonian-Early Carboniferous the eastern part of Siberia was affected by multi-stage rifting, which led to formation of a Late Paleozoic-Mesozoic passive margin. Four sections of the Lower Visean strata were studied in the northern part of the Kharaulakh Ridge, along the Lena River and Bykov Channel (north-east of Siberia). The studied sedimentary succession comprises two lithologically contrasting units: coarse-grained turbidites and hemipelagic cherts. Deposition occurred in a marine basin bounded by steep slopes, which is a key geomorphological feature facilitating deposition of coarse-grained turbidites. Within the studied sandy turbidites, several different zones of submarine sand-rich fans have been recognized. Integrated sedimentological and petrographical analyses allow us to interpret that the nearby uplifts composed of Proterozoic-Middle Paleozoic rocks were the main provenance areas for the Visean clastic rocks. Those uplifts were formed as a result of the latest stages of rifting in th
