CATALOGUE OF TYPE MINERAL SPECIMENS (CTMS)
The CTMS is now (2021) an evolving document, it is updated every month with NEW data directly from the IMA's Commission of New Minerals, Nomenclature and Classification. Additionally, data will be progressively audited and developed by the members of the IMA-CMs CTMS working-group alongside submissions from museum curators across the globe. Please get in touch with errors and corrections. The aspiration is that these Adobe Acrobat PDFs will be updated with a searchable database. The current team responsible for the updating and developing the CTMS would like to recognise the efforts of those before them; H-A.Stalder, A.R.Hölzel & A.R.Kampf. (LATEST UPDATE FEB 2021). Updates are compiled by IMA-CM-CTMS working-group volunteer Jacques Lapaire - THANKS!
