Ichnusaite (pronounced iknusa-ait) is a very rarely found
Sardegna, Italy in 2013.[2] The name is from the old Greek name of Sardinia, Ιχνουσσα, Ichnusa.[5]
This locality is also a place of discovery of the second natural thorium molybdate - nuragheite.[6]

Occurrence and association
Muscovite, nuragheite, and xenotime-(Y) are the associates of ichnusaite.[2]
Notes on chemistry
Ichnusaite is chemically pure.[2]
Crystal structure
The main features of the crystal structure of ichnusaite are:[2]
- electroneutral Th(MoO4)2(H2O)2 (100) sheets
- ThO7(H2O)2 and MoO4 polyhedra polymerize to give the above sheets
- sheets are stacked along [100] and held by hydrogen bonds
