Location

A young volcanic field with no particular name is located in NW Tibet. The field contains a cone in the Kekexili caldera, which was previously thought to have been in eruption based on a satellite photo in 1973. This is now considered not to represent an eruption.
There are several volcanoes that have erupted large fluuid lava flows in the area, similar to Hawaiian volcanoes.

Introduction:

Bamaoqiongzong volcano covers an area of 300 sq km and contains a perfectly preserved edifice NE of the summit and a lava flow that overlies Quaternary lake deposits. The Bamaoqiongzong area contains peralkaline phonolitic and foiditic rocks. Yongbohu contains 5 dacitic, trachyandesitic and andesitic vents. Qiangbaqian covers a broad area along the southern border of the Kunlun mountain range. Wei et al. (2003) did not note Holocene volcanoes in this region.
