BackgroundSedankinsky shield volcano lies at the SE end of a major graben extending NE from Kebeney volcano. It belongs to the Sedankinsky Dol volcanic field (also known as Sedanka Dol lava field), located immediately west of the Sredinny Range axis.
Eruptions at Sedanka Dol took place about 8000-10,000 years ago. The volcanic field consists of overlapping small strato- and shield-like volcanoes, and more than 100 cinder cones that form chains trending NE-SW, built on the southern and eastern flanks of Sedankinsky; lava flows from the youngest cones bank up against the steep-walled eastern margin of the graben. Most lavas are mafic in composition.
For this compilation the volcanic field area is considered to be up to 10 km wide and stretching about 25 km from south of Gorny Institute volcano towards the NNW between Tuzovsky volcano to the SW and Titila to the NE. Other workers (eg. Nekrylov et al., 2015) define the field to include the eight large edifices from Terpuk on the SW to Shishel on the NE.
