(See also: Uran Togoo - Tulga Uul Natural Monument) Khanuy-Gol (also known as Bulgan Volcanic Field, Chanuj Gol Hanui Gol or Hanuy Gol) is a volcanic field in Mongolia. Khanuy-Gol is located in the northern Hangai range, north of the settlement of Bulgan. The rocks erupted by the cones are olivine basalt with inclusions of ilmenite and xenoliths of peridotite in the case of the Togo cones. Some presumably Pleistocene lava flows are basaltic trachyandesites. The Selenga belt of Permian-Triassic age forms the basement of the field.
