In a remote section of Tanzania is the world's strangest volcano. Here, low temperature lava erupts as a black color, but soon cools to a bright white rock. This lava has a viscosity lower than water and is enriched in rare earth elements. Known as carbonatite, this unique lava has implications for mining operations around the globe which are searching for ancient deposits of it. So, why does this rare earth element enriched lava erupt?
