Volcanic Globule Rock from Mount Suswa, Kenya
A volcanic rock consisting of globules of lava is present on Mount Suswa, a Quater­nary volcano in Kenya. The rock is found on surfaces of sodalite phonolite lava flows (“globule-surface” lavas), where it seems to have formed by vesiculation of the upper parts of the flows. The rock also constitutes the entire volume of thin uniform sheets (“globule flows”) which may be globule-surfaces that slipped off the lava flows.
