Field Trips

The final organization of the field trips will be announced in the 2nd circular. If you are interested in organizing a field trip, please make your suggestions to the organizing committee. The dates of field trips that will run in conjunction with the colloquium are:

27-30 September 2012 Pre-Colloquium Field Trips
6-8 October 2012 Post-Colloquium Field Trips



Post-Colloquium Field Trip

Trip to Kışladağ (Uşak) Gold Mine, Kırka and Emet Borate Deposits

Field Trip Leaders: Cahit Helvacı, İbrahim Gündoğan, Yeşim Yücel Öztürk, Özgür Karaoğlu and E. Yalçın Ersoy


Day 1 - 6 October 2012, Thursday, Departure from İzmir.

Morning drive through Kula Volcanics on the way to Uşak.
Kula Volcanics: The Mediterranean region is a complex collage of microplates of different compositions and geological history, which originated in response to late Cretaceous-Cenozoic convergence of Africa-Arabia with Eurasia when numerous continental, microcontinental and ophiolitic terranes amalgamated together. The closure of numerous pre-existing oceanic basins was facilitated by oceanic subduction, continental drift, microplate rotations and migration of subduction arcs. This complicated interaction between orogenic processes and widespread extensional tectonics was especially dramatic in eastern Mediterranean, where Tertiary volcanism of contrasting geochemistry has taken place.

Kula Volcanics

Visit to Kışladağ Gold Mine : Located in one of several mid to late Tertiary volcanic complexes in Western Turkey, related to subduction along the Hellenic Trench southwest of Turkey. In the Kışladağ region, the volcanoes erupted onto a basement of metamorphic schist at the northeast margin of the Menderes Massif. Hosted by a number of latitic intrusive bodies. A coarsely porphyrytic latite is host to the bulk of the gold mineralization and has undergone extensive and intensive hydrothermal alteration. An early potassic phase of alteration is overprinted by later quartz-tourmaline and advanced argilic alteration. 135 Mt, 1.16g/t Au. The mine began commercial production on July 1, 2006. It is an open pit, heap leach operation with a planned 14 year mine life.

* Spend most of the day at deposit.

Kışladağ Gold Mine

* Lunch at Deposit. Afternoon drive to Afyon.
* Dinner and Accommodation: Afyon

Day 2 - 7 October 2012, Friday

Kırka Borate Deposit: The world’s largest borax (tincal) ore body. The most important B2O3 producer at present in the world, exhibits a symmetrical zonation in a lateral sense; it is comprised of a central body of Na borate (borax), an intermediate zone of Na-Ca borate (ulexite), and amarginal zone of Ca borate (colemanite) This mineral zonation is also developed in a vertical sense, although it is somewhat asymmetrical because of the presence of a discontinuous Mg borate horizon overlying the central body of borax. The genesis of such a mineral zonation in the Tertiary lacustrine borate deposits of the world has been attributed to a number of diagenetic processes.

* Spend most of the day at the mine. Lunch at Deposit.

Kırka Borate Deposit

* Afternoon drive to Emet (Approximately 3 hours drive).
* Dinner and Accommodation: Emet

Day 3 - 8 October 2012, Saturday

Visit to Emet borate deposit (world’s largest colemanite deposit). Emet is located 100 kilometers southwest of Kütahya, which was an important ceramic center in Anatolia in the past. The Emet borate deposits are situated in the middle of the known borate deposits of Western Anatolia. The Emet district includes Palaeozoic metamorphic rocks intruded by granite, and overlying Tertiary sediments associated with volcanic rocks. The deposits are mined by open-pit mining methods in the southern and northern basins.

Emet Borate Deposit

* Return back to İzmir.

Fee: 450 EUR in single rooms, 400 EUR in double rooms.

The price of the field trip covers transport, meals and accommodation from the 6th to 8th October (includes hotel accommodation in Afyon on the 6th October and in Emet on the 7th October).

Minimum number of participants: 20
Maximum number of participants: 40
