Bus-Obo
From Wikipedia, the free encyclopedia
47°07′N 109°05′E / 47.12°N 109.08°E[1] Bus-Obo is a 1,162 metres (3,812 ft) high cinder cone in Mongolia. The 90 metres (300 ft) high cone is formed by basaltic rocks. It may be of Pleistocene or Holocene age.[1]
It is located within a Caledonian orogenic belt in Mongolia, in the Middle Gobi area. A low velocity zone in the mantle is associated with Bus-Obo.[2] Other Pliocene to Pleistocene age lava flows and craters are found within the adjacent Orchon valley, their relationship to this cone is unknown.[3]
