Next meeting: March 11 - 14, 2018 at Skalní mlýn - the heart of the Moravian Karst, Czech Republic


Critical metals are metals whose availability is essential for high-technology, green and defense applications, but vulnerable to politically or economically driven fluctuations in supply. At present, this designation applies particularly to the rare-earth elements (REE), tantalum (Ta), niobium (Nb), lithium (Li), molybdenum (Mo) and indium (In). Their areas of application, supply market and mine to end-user pathways have undergone major changes in the past 25 years. Some of these changes have greatly affected metal prices, or raised concerns regarding the future of advanced technologies dependent on critical metals, and the national security of those countries whose demand for these metals for industrial and defense applications is satisfied entirely by imports.









In recent years, great progress has been made in the understanding of those geological processes that produce industrially viable concentrations of critical metals in igneous systems and supergene environments. At the same time, many aspects of metal transport and enrichment in the mantle and lower crust remain unclear, as do the driving forces and mechanisms behind hydrothermal and metasomatic processes leading to the formation of such important deposits as Bayan Obo, Mineville and Steenkampskraal.

CM2018 will provide a forum for further discussion of the origin, possible models of evolution REE, Nb, Ta deposits, and related processes in igneous, hydrothermal, metamorphic and supergene environments with maximum focus to carbonatites. The meeting will be accompanied by a rich social program and followed by a fieldtrip to several deposits in Czech Republic.

Experts - geologists, petrologists, mineralogists, geochemists, explorationists, technologists and market experts were invited to attend, contribute to the Workshop!

The First Workshop on the Geology of Critical Metals (CM2012) was held September 4-7, 2012, at Peking University in Beijing, China. The meeting was a great success, attracting many distinguished speakers from China and abroad (USA, UK, Germany, Canada, Japan, Czech Republic, Slovakia and Russia) and delegates from as far away as Brazil. The topics discussed ranged from the geology and evolution of Bayan Obo and other deposits, to regional metallogeny, to method development, to market considerations. The Workshop was followed by a fieldtrip to Xi’an and Mo deposits in central China.

The Second Workshop was organized from July 3, 2013, in Ulaanbaatar, Mongolia. It addressed key current issues facing critical-metals research, exploration, mining, remediation and global supply market. Almost fifty geologists, petrologists, mineralogists, geochemists, ore processing and market experts attended and contributed to the Workshop on the campus of the Mongolian University of Science and Technology (MUST). Additionally, 32 people went to the Gorkhi Terelj National Park for a 1 day fieldtrip to examine mined pegmatite deposits.The workshop was followed by a field trip to southern Mongolia, attended by 21 of the workshop participants.This trip involved a flight to Oyu Tolgoi mine camp, run by Rio Tinto, where 8 local geologists and organizers provided excellent logistical and scientific support. Geological component of this part of the tripwas led by Rio Tinto staff and by Mr. Garamjav of Turquoise Hill Resources, who was involved in the early stages of exploration and mine development. The field trip then spent 3 days visiting REE-enriched alkaline complexes to the east of Oyu Tolgoi (alkaline granites and pegmatites of Khan Bogd complex; carbonatites, syenites and REE hydrotermal veins of Lugiin Gol REE deposit; carbonatites, syenites and REE skarns of Ulgii Khiid complex), before returning to Ulaanbataar. We, the Organizing Committee of the CM2013 workshop are grateful to all sponsors which contributed and especially for the support of Rio Tinto, Tescan and IAGOD as well as to all geologists and geophysicists who looked after us so well during the CMM2013 and additional fieldtrips.










The Third Workshop was organized between August 9 - 14, 2015 at the Geological Institute in Apatity, at the heart of the Kola Peninsula in northwestern Russia. It was opened jointly with Lia Kogarko’s School on Alkaline Magmatism as an international workshop on Alkaline Magmatism of the Earth and Related Critical Metal Deposits. It was organized in the middle of Kola alkaline province worldwide known for the Khibiny apatite mines, loparite mines (and the world’s largest eudialyte reserve) at Lovozero, Kovdor magnetite-apatite-baddeleyite mine, Afrikanda magnetite-perovskite deposit, and a score of other exciting places. The meeting was a true success, attracting many distinguished speakers from Russia, USA, UK, Germany, Canada, Japan, Czech Republic, Slovakia, Turkey and Egypt - totally more than 130 scientists attended this critical metals meeting.

The Fourth Workshop entitled "Magmatism of the Earth and related strategic metal deposits" was organized between August 4 - 9, 2017 at the in Miass in the hearth of Ural, Russia.

Our colleagues from Miass have prepared several interesting excursions to the Vishnevogorsky miaskite-carbonatite massif, Mines (diverse pegmatites) of  Ilmen Nature Reserve , "Russian Brazilia" - granite & pegmatite complex, Medvedevskoe deposit - mineralogically interesting location with basic magmatic titanomagnetite ores and perovskite-bearing skarns,  Karabash Deposit - Au-bearing rodingites with intetesting rodingite and hydrotermal mineralisation.

There was organized also a school for young scientists in the same place and in the same time!
