'''Nadorite''' is a [mineral](/source/mineral) with the [chemical formula](/source/chemical_formula) PbSbO<sub>2</sub>Cl.<ref name=Mindat>{{cite web|url=http://www.mindat.org/min-2827.html|title=Nadorite|publisher=[Mindat.org](/source/Mindat.org)|accessdate=2008-04-16}}</ref> It crystallizes in the [orthorhombic](/source/orthorhombic) [crystal system](/source/crystal_system) and is brown, brownish-yellow or yellow in color, with a white or yellowish-white [streak](/source/streak_(mineralogy)).<ref name=Mindat />

Nadorite is named after [Djebel Nador](/source/Djebel_Nador) in [Hammam N'Bail](/source/Hammam_N'Bail), [Algeria](/source/Algeria), where it was first identified in 1870.<ref name=Mindat />

==Geologic occurrence==
Djebel Nador and [Djebel Debbar](/source/Djebel_Debbar) (both in the [Guelma Province](/source/Guelma_Province) of Algeria) are its co-[type localities](/source/type_locality_(geology)). Also found as an alteration product of [jamesonite](/source/jamesonite) in [Cornwall](/source/Cornwall), [England](/source/England).<ref name=Mindat />
