Honggeertu volcanic field
Volcanic field in China / From Wikipedia, the free encyclopedia
41.47°N 113°E / 41.47; 113[1] Honggeertu is a volcanic field in China, in the Nei Mongol Province.[1]
The field is formed by twelve basaltic cinder cones.[1] Some of the cones formed on a fault.[2] It may be of Holocene age.[1] Young lava flows from this field look much younger than these of Quaternary volcanoes in the neighbourhood.[3] The volcanism may originate in the tectonic effects of the movement of the Ordos Block. Seismic tomography indicates the presence of a low velocity region at the volcano.[4]
