IMA–CNMNC Approved Mineral Symbols
Mineralogical Magazine (2021), 85, 291–320 doi:10.1180/mgm.2021.43 Article IMA–CNMNC approved mineral symbols Laurence N. Warr* Institute of Geography and Geology, University of Greifswald, 17487 Greifswald, Germany Abstract Several text symbol lists for common rock-forming minerals have been published over the last 40 years, but no internationally agreed standard has yet been established. This contribution presents the first International Mineralogical Association (IMA) Commission on New Minerals, Nomenclature and Classification (CNMNC) approved collection of 5744 mineral name abbreviations by combining four methods of nomenclature based on the Kretz symbol approach. The collection incorporates 991 previously defined abbreviations for mineral groups and species and presents a further 4753 new symbols that cover all currently listed IMA minerals. Adopting IMA– CNMNC approved symbols is considered a necessary step in standardising abbreviations by employing a system compatible with that used for symbolising the chemical elements. Keywords: nomenclature, mineral names, symbols, abbreviations, groups, species, elements, IMA, CNMNC (Received 28 November 2020; accepted 14 May 2021; Accepted Manuscript published online: 18 May 2021; Associate Editor: Anthony R Kampf) Introduction used collection proposed by Whitney and Evans (2010).

Extreme Chemical Conditions of Crystallisation of Umbrian Melilitolites and Wealth of Rare, Late Stage/Hydrothermal Minerals
Cent. Eur. J. Geosci. • 6(4) • 2014 • 549-564 DOI: 10.2478/s13533-012-0190-z Central European Journal of Geosciences Extreme chemical conditions of crystallisation of Umbrian Melilitolites and wealth of rare, late stage/hydrothermal minerals Topical issue F. Stoppa1∗ and M. Schiazza1 1 Department of Psychological, Humanistic and Territory Sciences of G.d’Annunzio University Chieti-Pescara, Italy. Received 01 February 2014; accepted 07 April 2014 Abstract: Melilitolites of the Umbria Latium Ultra-alkaline District display a complete crystallisation sequence of peculiar, late-stage mineral phases and hydrothermal/cement minerals, analogous to fractionated mineral associations from the Kola Peninsula. This paper summarises 20 years of research which has resulted in the identification of a large number of mineral species, some very rare or completely new and some not yet classified. The pro- gressive increasing alkalinity of the residual liquid allowed the formation of Zr-Ti phases and further delhayelite- macdonaldite mineral crystallisation in the groundmass. The presence of leucite and kalsilite in the igneous as- semblage is unusual and gives a kamafugitic nature to the rocks. Passage to non-igneous temperatures (T<600 ◦C) is marked by the metastable reaction and formation of a rare and complex zeolite association (T<300 ◦C). Circulation of low-temperature (T<100 ◦C) K-Ca-Ba-CO -SO -fluids led to the precipitation of sulphates and hy- 2 2 drated and/or hydroxylated silicate-sulphate-carbonates. As a whole, this mineral assemblage can be considered typical of ultra-alkaline carbonatitic rocks.
