Katunga Volcano | John Seach
Uganda
0.47 S, 30.18 E
summit elevation 1707 m
Tuff cone
Katunga volcano is located in SW Uganda, 40 km SE of Lake Edward.
Flows of katungite are only found at Katunga volcano. Katungite contains mainly biotite and augite.
The rock known as katungite was originally described as melilite-basalt or olivine-melilitite. Detailed investigation of the specimens from the two Katunga flows show they differ from olivine-melilite in being both potash-rich and free from augite; therefore a new name was used.
katungite = proto-katungite + biotite-pyroxenite (+ very little olivine).
