Medan gunung api · Chad · 2000 m

Small scoria cones and lava flows of the Tarso Tôh volcanic field can be seen in the large darker-brown 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. · Foto: NASA Landsat 7 image (worldwind.arc.nasa.gov) · Wikimedia Commons

Ringkasan geologi

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 Volcanic Complex. 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).
