Mineralogical and rock collections

The mineralogical collections

The mineralogical collections bring together more than 30.000 specimens, from the systematic sample to the show display piece, and from the specimen of national interest to the representative specimen for worldwide deposits. These collections are subdivided like that:

  1. the national collection
  2. the regional collections, essentially focused on boundary areas (called ‘great area’) and subdivided into Mineralogy of France, Belgium and Germany. They contain exceptional and unique specimens for the great area.
  3. the african and brazilian collections, contain among other things the famous collections from J-M Pendeville, A. Rostenne and J. Cassedanne.
  4. the systematic collection, contains minerals coming from famous worldwide deposits, a lot of rare species, and some holotypes (and cotypes)

The holotypes in our collections are:

  • the Thoreaulite discovered in 1933 [SnTa2O6] at Manono, Congo.
  • the Burtite discovered in 1981 [CaSn(OH)6] at El Hammam, Maroc.
  • the Foordite discovered in 1988 [(Sn,Pb)(Nb,Ta)2O6] at Lutsiro, Rwanda.
  • the Qinghéiite-Fe2+ discovered in 2009 [Na2Fe2+MgAl(PO4)3] at Sebastiao Cristino, Brazil.

The rock collection

The rock collection is composed by approximately 1400 samples with something like 300 specimens constituting a representative sampling of the rocks diversity from Grand-Duchy; 300 rocks coming from Germany and more than 200 samples with associated thin sections. These collection must be enlarged in the future and tend to a reference rock collection for geologist and archeologist.

All our collections are opened to scientist for studies. Specimens could be loaned for national and international exhibits, with a preliminary loan agreement.
