Lepersonnite-(Gd) is a very rare uranium and rare-earth mineral with the chemical formula . It occurs with bijvoetite-(Y) in the Shinkolobwe deposit in the Democratic Republic of the Congo, famous for rare uranium minerals. It was the first confirmed mineral with essential gadoliniumGadolinium: The mineralogy of gadolinium - Mindat. org and remained the only gadolinium dominant species until the description of Monazite-(Gd) in 2023.
