Bufumbira Volcano | John Seach



1.23 S, 29.72 E
summit elevation 2440 m
Cinder cones

Bufumbira volcano is located in SW Uganda. The volcano consists of 40 cinder cones and lava flows.

The Bufumbira depression is bounded by high and deeply dissected mountains.

A prominent feature of the Bufumbira lava field are several long ridges, formed almost entirely of ash and scoria. The most prominent of the ridges are Bunagana, Ndakilye-Migeshe, and Karambe. The ash ridges follow lines of weakness coinciding with steeply dipping sedimentary rocks.

Most of the smaller eruption centres are composed of ash, scoria, and pumice.

The field is one of the largest leucite-bearing areas of the world. Rocks containing leucite are scarce on earth.
