Doyleite is a rare aluminum trihydroxide mineral named in honor of its discoverer, the Canadian physician Earl Joseph (Jess) Doyle.

[4] Doyleite grows in small square tabular crystals, which form rosettes.

[6] Some specimens are coated with a thin film of dark brown amorphous material, thought to be iron oxide.

There is good correspondence between the AFM images of doyleite's (010) surface and the calculated structure.

The hydroxyl group's intra-layer interactions show no Raman scattering in contrast to its polymorphs.
