Kleusonit
Kleusonite adalah anggota kelompok mineral crichtonite dengan rumus kimia (Pb,Sr)(U4+,U6+)(Fe2+,Zn)2(Ti,Fe2+,Fe3+)18(O,OH)38. Kelompok mineral ini mengandung sekitar tiga belas titanat logam kompleks. Struktur mineral kelompok ini diperumit oleh seringnya kembaran skala halus dan metamiktisasi karena unsur radioaktif.
