The Tarso Tôh Pleistocene-to-Holocene volcanic field in the NW part of the arid Tibesti Range of Chad contains 150 scoria cones and two maars. Basaltic lava flows fill valleys and plains over an area of 80 km in an E-W direction and 20-30 km in a N-S direction in the area north of the more well-known Tarso Toussidé volcano. The flows were erupted over a basement of Precambrian schists on the east and Paleozoic sandstones on the west. Sediments within the Begour maar were radiocarbon dated at 8300 +/- 300 years (Hagedorn and Jakel, 1969).
The Global Volcanism Program is not aware of any Holocene eruptions from Tarso Toh. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tarso Toh 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.

|Small cinder cones and lava flows of the Tarso Tôh volcanic field can be seen in the large darker-brownish area at the center of this NASA Landsat image. This Pleistocene-to-Holocene volcanic field in the Tibesti Range of Chad covers a 30 x 80 km area and contains 150 scoria cones and two maars. Basaltic lava flows at Tarso Tôh were erupted over a basement of Precambrian schists and Paleozoic sandstones. The black lava flows at the very bottom-center are distal lava flows from Tarso Toussidé volcano.

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.
