Lanthanites are a group of isostructural rare earth element (REE) carbonate minerals. This group comprises the minerals lanthanite-(La), lanthanite-(Ce), and lanthanite-(Nd). This mineral group has the general chemical formula of (REE)2(CO3)3·8(H2O). Lanthanites include La, Ce, and Nd as major elements and often contain subordinate amounts of other REEs including praseodymium (Pr), samarium (Sm), europium (Eu) and dysprosium (Dy). The lanthanite crystal structure consists of layers of 10-fold coordinated REE-oxygen (O) polyhedra and carbonate (CO32−) groups connected by hydrogen bonds to interlayer water molecules, forming a highly hydrated structure.

  • Lanthanit (La,Ce,Nd)2(CO3)3·8(H2O) är ett sekundärt mineral som påträffats vid nya Bastnäsfältet, Riddarhyttan, Skinnskattebergs kommun i Västmanland. Färgen är färglös, vit, gul eller svagt rosa. I friskt tillstånd är lanthanit färglös med en svagt rosafärgad nyans. På stuffer som varit utsatta för luftens inverkan är mineralet matt och vitt till färgen. Lanthanit uppvisar pärlemorglans. Uppträder som tunna beläggningar och lameller. Den vanligaste kristallformen är som en tunn fyrsidig tavla, men även andra former har iakttagits. Lanthanit förekommer på sprickytor i ceriummalm, ibland tillsammans med vismutglans och kopparkis. Påträffas även i drusrum och i amfibolskarn ofta åtföljt av kvartskristaller, , kloritfjäll, magnetit och malakit. Bastnäs är typlokal för lanthanit. (sv)
  • Лантані́т (англ. lanthanite; нім. Lanthanit m) — мінерал, водний карбонат лантану, диспрозію та церію острівної будови. Названий за основним елементом, що входить до його складу (W. K. Haidinger, 1845). (uk)
