14 – 20 May 2018
Çesme, Izmir, Turkey
European Federation of Geologists (EFG) and Maden Jeologlari Dernegi (MJD) / Turkish Association of Economic Geologists.
- Optional Field Trip
- Council Meeting
- Euroworkshop Grant
- How to arrive
- Clarification concerning the EuroWorkshop in Turkey
The European Federation of Geologists (EFG) and the Maden Jeologları Derneği (MJD), Turkish Association of Economic Geologists, will co-organise a EuroWorkshop on “Epithermal Gold Deposits in the Big Peninsula” in Çeşme (on the western coast of İzmir, Turkey) on 17 and 18 May 2018. The EuroWorkshop will have an optional Pre-Workshop Field Trip between 14-16 May 2018.
The EuroWorkshop 2018 aims to understand;
- How the low, intermediate and high sulfidation epithermal mineralization have been formed
- Metallogeny and current understanding of the epithermal deposits
- Success and failure on exploration and mining for epithermal deposits in Turkey
EuroWorkshops are a new form of professional training that EFG proposes to European Geologist title holders and other geoscientists. This new type of training activity will intensify the professional exchange of ideas and the contacts between geologists from all over Europe and will also strengthen the European idea within the family of geoscientists. The EuroWorkshops will also provide applied training for students and young professionals, offering special conditions for them. This way, young geologists will become familiar with the vision and mission of EFG, while EuroGeologists will have the chance to upgrade their knowledge and experience since the workshops are CPD certified.
The 75th EFG Spring Council Meeting will be held on 19-20 May, 2018 (for EFG delegates only).
Turkey, a collage of complex terranes in the Tethyan Belt, has largely been shaped by interplay of several subduction and collision events related to the opening, final closure and terminal suturing of the Tethys oceanic realms, since the Permian. The mineral deposits in this collage are particularly resulted from subductional and post-collisional events due to closure of NeoTethys ocean and collision between Afro-Arabian passive margin and Eurasian active margin since the late Cretaceous to Miocene. Collectively, this led to fertile metallogenic environment with abundant porphyry Cu, orthomagmatic, volcanogenic massive sulfide, skarn, epithermal, and ironoxide-Cu-Au deposits, clustering in narrow arc segments, and post to late-orogenic transtensional and transpressional settings. Turkey has a long history of mining and hosts some world-class epithermal gold deposits that are being exploited commercially. Over 500 gold occurences, prospects and deposits are known occuring in Turkey, and they are mainly clustered in three metallogenic provinces; western Anatolia with the Biga Peninsula in particular, northeastheastern Anatolia, and eastern central Anatolia.
Turkey has become an attractive destination for gold mining companies, proudly taking the title of Europe’s largest gold producer. The initiation of full production of first gold mine of Turkey at Ovacik (Bergama, Izmir) in 2001, has revolutionized the gold exploration and mining, and triggered many active gold mines to come into production such as Kışladağ porphyry Au, Çöpler porphyry Cu-Au, Efemçukuru epithermal Au-Ag, Ovacık epithermal Au-Ag, Çukuralan epithermal Cu-Au, Mastra epithermal Au, Kaymaz epithermal Au, Himmetdede shear zone-hosted Au, Bolkardağ lateritic Au, Altıntepe epithermal Au, Kızıltepe epithermal Au and Midi epithermal Au-Ag. Apart from the deposits being mined, the last five years were a major era for many ongoing feasibility and development gold projects, such as Mollakara, Öksüt, Karadere, Sahinli, Inlice, Kartaldag, Yenipazar, Ağı Dağı, Kirazlı and TV tower.
The significant mineral deposits of the Biga Peninsula are temporarily and spatially associated with magmatism related to mainly to collisional and post-collisional tectonic regime between 42 Ma to present. This magmatism has been generated in response to final closure of the NeoTethys Ocean along Hellenic-Aegean subduction due to closure of the Mediterranean Sea, the remaining NeoTethys ocean to the west. These events generated voluminous calc-alkaline and alkaline magmatism, that reflects a transition from arc to post-collisional settings and effects of collision and onset of crustal thickening and subsequent extension since the ca. 42 Ma.
The aim of this EuroWorkshop is to provide an outlook to and a deeper understanding of the epithermal gold deposits of Turkey with the Biga peninsula in particular. This will also enable the participants to evaluate the current exploration programs and the discoveries of gold deposits in the area, to contribute to society to see successes and failures on exploration and discoveries. Finally, the EuroWorkshop will provide a general overview of the present status of gold discovery and mining in Turkey.

It is possible to go from the İzmir Adnan Menderes Airport to Çesme by bus or taxi. The information about the company providing this service (HAVAS) can be found here in English. The bus stop it is at the same airport, the destination of the bus is “Çesme Bus Terminal”. The price of the ticket will be 5-6 EUR including 18%VAT and the travel will be 90 minutes long. Going by taxi can be expensive.
If going by bus, once in the Çesme Bus Terminal it is recommended to take a taxi to arrive at the hotel.
In light of recent actions of the Turkish government, we received comments from concerned colleagues on the upcoming Council meeting and EuroWorkshop that will take place in Izmir, Turkey.
We understand these concerns. As a not-for-profit organisation whose purpose is to represent the professions of geology in Europe, we distance ourselves from the political »side-taking«, and we stand in the position that geological practice has to be independent of political, religious, gender or racial constraints. Our Turkish colleagues from MJD/TAEG (Maden Jeologları Derneği/Turkish Association of Economic Geologists) are independent of the Turkish government, and they share EFG values.
Consequentially, despite the policies of the Turkish government and the current conflict situations in the mid-east region, the EFG Board decided not to cancel the Council meeting in Izmir, in support of the independence of TAEG/MJD.
We sincerely hope that you understand our decision.
