Panguite: one of the oldest solar minerals
Panguite was discovered and named by Chi Ma at Caltech. The name is after Pan Gu, the giant in ancient Chinese mythology, who created the world by separating the heaven and the earth from chaos in the beginning, in allusion to the mineral with an ultra-refractory origin, being among the first solid materials formed in the solar system, likely 4.567 billion years old.
