A rare mineral composed of calcium aluminum silicate, typically found in metamorphic rock formations.
Named after Axel Fredrik Arfvedson, a Swedish chemist and mineralogist from the 1800s, with the mineral suffix '-ite' added. The name honors his contributions to mineralogy and chemistry despite the mineral being discovered after his death.
Arfillite represents a fascinating pattern in science: we name minerals after the people who studied them, creating a kind of immortality in the periodic table. Arfvedson himself discovered lithium, so this mineral is a tribute to a scientist whose work literally gave us new elements.
