The Udokan Plateau is a volcanic field in Transbaikalia, Russia.[2] It covers a surface area of 3,000 square kilometres (1,200 sq mi) northeast of Lake Baikal in North Asia. Volcanism in the Udokan Plateau included both basaltic lava flows and later individual volcanic cones. Volcanism commenced in the Miocene and continued on into the Holocene.

Volcanism in the field ranges from lava flows forming thick lava flow sequences formed out of basalt to explosive eruptions forming cinder cones accompanied by lava flows and ignimbrite eruptions during the late stages of volcanic activity. Volcanic activity commenced 14 million years ago and the youngest three radiocarbon dates indicate persistence of volcanic activity into the Holocene. Recent seismic activity has been reported.
