La drysdal·lita és un mineral de la classe dels sulfurs, que pertany al grup de la molibdenita. Va ser anomenada en honor d'Alan Roy Drysdall, geòleg i director del Servei Geològic de Zàmbia. (ca) Drysdallite is a rare molybdenum selenium sulfide mineral with formula Mo(Se,S)2. It crystallizes in the hexagonal system as small pyramidal crystals or in cleavable masses. It is an opaque metallic mineral with a Mohs hardness of 1 to 1.5 and a specific gravity of 6.25. Like molybdenite it is pliable with perfect cleavage. It was first described in 1973 for an occurrence in an oxidized uranium deposit near Solwezi, Zambia. It was named for Alan Roy Drysdall, the director of the Zambian geological survey.

Drysdall, director de investigaciones geológicas de este país, en cuyo honor se le puso nombre. (es) Drysdallita sulfuro motako minerala da eta molybdenite taldearen kidea da.
