Doyleite

Doyleite is a rare aluminum trihydroxide mineral named in honor of its discoverer, the Canadian physician Earl Joseph (Jess) Doyle. It was first definitively described in 1985 (although a partial description was published in 1979) and it is approved by the IMA. It was described from Mont Saint-Hilaire, where it is extremely rare.
