Popis:
Cinder cones of the Bufumbira volcanic field — in SW Uganda (center), lie north of the large stratovolcanoes of the NE part of the Virunga Mountains.
- The roughly 40 cinder cones occur in clusters and were erupted along lineaments; they are typically breached on one side by lava flows.
- The Bufumbira rocks are noted for their unusual ultrapotassic chemistry.
- Muhavura (center) and Sabinyo (left) stratovolcanoes are visible at the bottom of this Landsat image.
