Museu de Ciències Naturals de Barcelona


Science Scientific departments Mineralogy

The mineralogy collection contains over 26,000 specimens, which form the basis for carrying out activities related to research, dissemination and scientific communication.

The collection is divided into four sub-collections, according to the features of the specimens:

  • General mineralogy: made up of the most significant mineral samples. It represents the collection’s greatest cultural heritage. At present, this sub-collection consists of 15,680 registered items and contains over 1,000 well-identified species.
  • Micromounts: made up of small mineral samples that require the use of magnifying optical aids (between 20X and 60X) in order to observe them. This sub-collection consists of 9,500 registered items and contains 2,500 identified mineral species, some of which are extremely rare. It is a reference collection for mineral characterisation studies, often related to the description of new species.
  • Gemmology: made up of 998 registered items, it includes all the faceted, polished and cut minerals. Worthy of note is the good representation of gemstones from different locations on the Iberian Peninsula.
  • Meteorites and related items: made up of 66 registered items. This section contains meteorites, tektites and impactites. It contains specimens from various locations around the world, including samples of historic meteorites in Catalonia, such as those from Terrassa (1704), Nulles (1851), Canyelles (1861) and Garraf (1905).

Projects associated with the collection

With regard to the documentation, conservation and dissemination of the collection, the main projects carried out by the Mineralogy Department are:

  1. The documentation and characterization of specimens from different sub-collections.
  2. The conservation and improvement of the protocols related to the preservation of specimens sensitive to environmental conditions, radioactive minerals and asbestos.
  3. The PangeaDB® Project: the development of a new collection management tool created by the MCNB.
  4. The dissemination and publication of data associated with the collection’s specimens on online public portals.
  5. The dissemination and carrying out of activities related to mineralogy and the Earth sciences..

Research projects

Research projects developed in the Mineralogy Department are included in the following continuous lines of research:

Critical metals for the energy transition
