There are strange and wondrous volcanoes here, though. Natrocarbonatite volcanoes erupt with flows that are about as viscous as cooking oil and which are too cool to see glowing with the naked eye. The carbonatite lava beds left behind by a natrocarbonatite volcano quickly degrade in Earth's damp atmosphere, crumbling away.

This does eventually come back to A Miracle of Science. Natrocarbonatite is composed mostly of two minerals, one of which is called nyerereite. You may recognize the name of Benjamin's boss, Gustave Nyerere, in that mineral's name. Nyerereite is named for the same man Chief Nyerere is - Julius Nyerere, the first president of Tanzania.
