A group of late-Pleistocene to Holocene phonolitic lava domes is located at the SW end of the Usangu Basin, NE of the Poroto Mountains. Vents of the SW Usangu Basin volcanic field are located along NNE-trending normal faults (Ebinger et al., 1989). However, Fontijn et al. (2012) considered the volcanic centers in this area, forming a phonolite dome field, to not be part of the late Cenozoic stage of volcanism in the Rungwe Volcanic Province; the most recent dated sample was 0.57 Ma.
