The geology collections hold an important natural heritage and consist of three sizeable collections of national and international reference: Palaeontology (fossils and thin sections), Petrology (rocks and thin sections) and Mineralogy (minerals, gems and meteorites).
The collections are housed in the Museum, where they are conserved and studied by geology experts who document the items by inventorying and cataloguing them and then computerising and publishing the databases to facilitate their use by the scientific community. The specialised laboratories at the Museum are used for these purposes.
