Taryatu-Chulutu (Mongolian: Тариатын чулуут, romanized: tariatyn chuluut, "rocks of Tariat") is a volcanic field in Mongolia. It is part of a volcanic area in Central Asia in the Hangai range that may be linked to the rifting of the Lake Baikal Rift. The field itself is located within the valleys of the Chuluut and Suman rivers. Volcanic activity occurred in the Miocene, Pliocene, Pleistocene and Holocene. The Khorgo cinder cone erupted during the Holocene and lava flows from it formed a lava dam generating Terkhiin Tsagaan Nuur lake.
