Fledgling mantle plume may be cause of African volcano's unique lava (PhysOrg.com) -- Nyiragongo, an active African volcano, possesses lava unlike any other in the world, which may point toward its source being a new mantle plume says a University of Rochester geochemist. The lava composition indicates that a mantle plume -an upwelling of intense heat from near the core of the Earth -may be bubbling to life beneath the soil of the Democratic Republic of the Congo. The findings are presented in the current issue of the journal Chemical Geology.
