Session – The Ever-Growing Mineral Diversity in the Earth and the Solar System: New Minerals, including Nano- and Biominerals, and Related Nomenclature/Classification Issues

New methods as well as refined existing methods open the way to detailed studies of minerals and they also broaden the field to explore minerals that occur only as micro- or even nanopartices. An increasing number of minerals discovered in samples of extraterrestrial bodies as well as phases observed in samples formed through interactions at the geo-bio interface highlights aspects of increasing importance in mineral science.

The IMA Commission on New Minerals, Nomenclature and Classification (CNMNC) is central to several of these aspects. Many recently described new minerals underline the need for modifications of existing mineral nomenclature. The CNMNC remains very active with respect to mineral nomenclature and classification matters by publishing guidelines and recommendations on mineral names and mineral groups. The Commission reviews new mineral submissions and handles discreditation matters. This session will address current nomenclature and classification issues in mineral science and it will offer a forum for discussions on potential needs to modify existing mineral nomenclature in the light of recently discovered minerals.
