Daliranite is a sulfosalt found in northwestern Iran with a general chemical formula of PbHgAs2S5. The mineral presents a vibrant orange-red color and fibrous habit which makes it resemble the oxide being confused by its similarities in early studies. Named after Dr. Farahnaz Daliran, who has important contributions to research on ore deposits in Iran, this mineral was accepted by the International Mineralogical Association (IMA) in 2007.

== Occurrence == Daliranite is found in the Zarashouran deposit which is an Au-As deposit located near the town of Takab in the province of West Azerbaijan in Iran. The mineral is not found alone as it is found in samples composed mostly of the sulfide mineral orpiment. This sulfosalt grows within cavities of orpiment and is always found covering other minerals therefore it is believed to crystallize last. The temperature of formation ranges between 157 and 193 °C forming at the same time as quartz II.
