A volcanic field in NE Tibet contains a number of late-Cenozoic volcanoes (Tong et al., 1988). Several Hawaiian-style volcanoes are present in this area. Bamaoqiongzong 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 (Whitford-Stark, 1987). The Bamaoqiongzong area contains peralkaline phonolitic and foiditic rocks. Yongbohu contains five 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. A cone in the Kekexili caldera, once thought to be observed in eruption on a satellite photo in 1973, is now considered not to have been historically active (Kidd 1990, pers. comm.).

The Global Volcanism Program is not aware of any Holocene eruptions from Unnamed. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Unnamed page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
