Background:

A small basaltic tephra cone on the edge of the Usangu escarpment, overlooking the Usangu basin north of the Poroto Mountains, was considered by Ebinger et al. (1989) to be of probable Holocene age, based on lack of vegetative cover. A lava flow traveled westward away from the rift valley along the back-tilted flank of the rift. The exact location of this feature is uncertain and is not obvious at the mapped location using satellite imagery. More recent papers do not reference this location or provide age dates for the sample taken by Ebinger et al. (1989). Fontijn et al. (2012) considered the volcanic centers in the adjacent SW Usangu Basin area to be unrelated to the late Cenozoic stage of volcanism in the Rungwe Volcanic Province.
