Post-conference fieldtrip: 16. August-24. August 2008

Departure/Arrival: Köln / Köln

Aproximated costs: 1010€
Preliminary prices include: Train ticket from Frankfurt to Cologne airport. Flight costs Cologne-Skopje Bus transfer all over the field in Macedonia, Greece and Turkey All accommodations in Macedonia including all Lunches and Dinners Overnight Ferry from Thessaloniki to Lesbos, including reservation for 2 bad cabin. All accommodations in Lesbos including all Lunches and Dinners Ferry Ticket from Lesbos to Dikili (Turkey) All accommodations in Turkey including all Lunches and Dinners.

IMPORTANT!!
Preliminary prices do not include: Flight tickets from Turkey. We decided to live on participant the date of the departure from Turkey, as many of them were interested about spending a few days at the end of the trip visiting sites in Turkey. Many flight agencies fly from Antalia international airport, including cheep ones like Germanwings, Sunexpress etc. Visa costs for Macedonia, Greece and Turkey-you need to get informations about the necessary visas.
We cannot fix the costs at the moment, because some of the prices are not yet fixed (e.g. Ferry costs within Greece, and we made our recalculations on the basis of last-year prices).

KULA volcanic field-Turkey

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.


Preliminary route of our fieldtrip.

This field trip will highlight various stages in the evolution of the eastern Mediterranean volcanic provinces. We will concentrate on lamproites, ultrapotassic rocks and alkali basalts, but also we will discuss on the field the major features of general geology of the areas. Mediterranean lamproites not intrude any cratonic basement or nearby orogenic belts, which is typical for "unorogenic" lamproites, like e.g. Leucite Hills. They occur in orogenic belts which mark the locus of continental convergence between African and Euroasian tectonic plates. They are genetically closely related with the other orogenic and postorogenic volcanics and their connection with subduction processes is inescapable.

We will fly from Köln to Skopje, the major city of Macedonia.  We will start in northern Macedonia (FYROM) where fieldtrip stops will include the youngest Mediterranean lamproites (9-2Ma) with small groups of volcanic cones, lava flows, plugs and dykes. We will also visit the outcrops of the ophiolitic rocks which constitute one of the largest exposures of mantle rocks on Earth and metamorphic terrains accreted during the closure of Neo-Tethys.

KURELJ diatreme-MACEDONIA (FYROM)

After Macedonia we continue to Greek volcanic island Lesbos (ferry overnight) where we plan to see lamproitic dykes but also the famous Petrified Forest. The final country of our excursion will be Turkey. In Tertiary time, Turkey was a site of intense volcanic activity related to the collision and subduction along the Hellenic and Cyprus arcs. Turkey presents a key area for study of Mediterranean style subduction, and related volcanism. We will visit two lamproitic provinces: the Western Anatolia-Aegean province which was dominantly affected by voluminous Tertiary magmatism with orogenic geochemical signature and in which the lamproitic rocks are related to the end of the orogenic phase, and the N-S-trending Kyrka-Afyon-Isparta volcanic province. Also, we will visit Kula volcanic field which erupted between about 1.1 million and historical times, spectacular ignimbrite fields around Foca and Afyon, and a number of historical places from Hellenistic and  Roman times. The fieldtrip will finish in Antalya, where our plane will fly back to Köln.

This 7-day field trip will present a quick, intensive overview into volcanism and tectonism in this dynamically still active region. We invite you to discuss with us origin models and examine geological features of this exciting area, but also to have fun!
