The Jebel Umm Arafieb volcanic field, also known as Jebel Umm Marafieb, is located in the Bayuda desert of NE Sudan, immediately west of the Nile River, NE of the capital city of Khartoum. Jebel Umm Arafieb consists of a low-angle shield volcano of basanitic-to-trachybasaltic composition formed of several overlapping aa lava flows erupted from a vent now capped by a spatter cone. Very well-preserved cones, lava flows, and explosion craters were considered by Almond (1974) to be of late-Pleistocene or Holocene age.

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

The Global Volcanism Program has no synonyms or subfeatures listed for Jebel Umm Arafieb.

The dark area at right-center to the left of the bend in the Nile River in NE Sudan is the Jebel Umm Arafieb volcanic field, also known as Jebel Umm Marafieb. Located in the Bayuda Desert NE of the capital city of Khartoum, this volcanic field consists of a low-angle shield volcano formed of several overlapping aa lava flows erupted from a vent now capped by a spatter cone.

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.
