Andrianovite is a very rare mineral of the eudialyte group,[2] with formula Na12(K,Sr,Ce)6Ca6(Mn,Fe)3Zr3NbSi(Si3O9)2(Si9O27)2O(O,H2O,OH)5.

[4] Andrianovite is unique among the eudialyte group in being potassium-rich (other eudialyte-group species with essential K are davinciite and rastsvetaevite[2]).

[3] Andrianovite was discovered in pegmatites of Koashva open pit, Khibiny massif, Kola Peninsula.

It coexists with aegirine, lamprophyllite, lomonosovite, microcline, mosandrite, natrolite, sodalite (silicates) and villiaumite.

Minor substituting elements are lanthanum, neodymium, yttrium, titanium, barium, hafnium and aluminium.
