Background:

The carbonatite lavas and tuffs of the Fort Portal volcanic field in Uganda, NE of Mount Ruwenzori between Lake Albert and Lake Edward, consists of a group of tuff cones and maars covering an area of about 145 sq km. About 50 volcanic vents, some of which now contain crater lakes, were erupted through basement rocks of Precambrian gneiss in an WSW-ENE-trending area north of the town of Fort Portal. Several additional vents are located in the Kasekere (Rusekere) area to the NE. Radiocarbon dates of about 4700 to 4000 years ago were obtained from ash deposits from the Fort Portal volcanic field. Holmes (1950) noted that Kasensankaranga Crater in the Fort Portal area means "spewer of roasted material," implying an historical age.
