}}Sengierite is a rare oxide and hydroxide mineral, chemically a copper and uranyl vanadate, belonging to the carnotite group. Its chemical formula is Cu2(OH)2[UO2{{Pipe}}VO4]2·6H2O.[1][2]

Sengierite was first discovered at the Luiswishi Mine about 20 km north of Lubumbashi in Katanga Province in the Democratic Republic of the Congo and was first described in 1949 by Johannes F. Vaes and Paul F. Kerr, the mineral was named after Edgar Sengier (1879–1963), a former Director of the Union Minière du Haut Katanga.[3]
