International Earth Science Colloquium on the Aegean Region IESCA 2012 ABSTRACTS BOOK October 1, 2012 – October 5, 2012 Dokuz Eylül University, Izmir, TURKEY i ii WELCOME Dear colleagues, It is a great honour for us to welcome you to the International Earth Sciences Colloquium on the Aegean Region, IESCA-2012. The Aegean Region has been home to a variety of races and peoples over the centuries. With its matchless beauty, which came about via the operation of various geological processes through the ages, from ancient times this region has hosted population, cultural and commercial centres for a plethora of different civilizations; Pergamum, Smyrna, Sardis, Ephesus and Miletus are but a few examples. From the days of the ancient Aegean civilizations, people with various cultures and beliefs, hailing from the Mediterranean Region, from Anatolia, from Mesopotamia and beyond, have lived on this soil in peace. Since the times of Thales and Anaximander, geological studies have been carried out in this region. Many scientists have engaged in research and mineral exploration, and all have contributed to the understanding of the geology and natural resources of the Aegean Region. And many earth scientists are still at work here, including institutes and individuals from around the globe, insofar as this region presents so many key geological problems and provides an exceptional laboratory in which we may come to further understand the ever-developing earth sciences. The Aegean Region plays a key role in our understanding of geological problems of the eastern Mediterranean region and preserves important records of geological processes which have operated in a zone of convergence. Many examples of metamorphic, magmatic and sedimentary processes, and the related economic mineral deposits and energy resources of the region, have already been extensively studied by earth scientists from around the world. This geological wealth is a consequence of a regional tectonic setting in which several continental blocks were amalgamated via Tethyan subduction events, giving rise to the present configuration of the region. The colloquium has been organized broadly along the lines of several regional geological topics, including tectonics, metamorphism, magmatism, sedimentation, geophysical research, mining and mineral deposits, energy resources and engineering geology. We believe that new advances in our knowledge of the geology of the Aegean Region will be discussed extensively and that the colloquium will encourage the collaboration of scientists from different countries in the international scientific endeavour. This international meeting has been designed as a forum to bring together geoscientists from around the world so that they might discuss the regional geology and processes at work in this extraordinary region—so active that it is one of the world’s great natural geological laboratories. Conference participants and guests will also examine the geology and regional culture via an array of field trips. In recent years, global climate changes have profoundly demonstrated the magnitude of the environmental threats to our world. One of the main reasons that 2008 was designated “Year of the Earth” by UNESCO was -through resources provided by the earth sciences- to focus on what might be done to create a cleaner, healthier, and more productive world. Accordingly, the maximum reduction of risks associated with natural events such as earthquakes, landslides, floods and erosion; the protection of subsurface and surface waters; the prioritization of new, clean energy sources; the iii most productive and effective utilization of underground resources; and, most importantly, the creation of a sustainable environment, are among the fundamental issues upon which earth scientists must train their attention. The main goals of this colloquium are to provide 1) a platform for the communication of new ideas and 2) a setting for the possible obtainment of interdisciplinary solutions pertaining to the natural resources and geological problems of the Aegean Region by eminent scientists from all over the world. Hosting this distinguished group of scientists is a great privilege for me, and the calibre of these researchers makes me confident about the success of this meeting. I greatly appreciate and thank you all for your efforts and contributions. I extend my heartfelt thanks to all of the prominent earth scientists from many different countries who have given of their valuable time to contribute to the success of this gathering, who have given encouragement and practical and financial support, and who will share with us here their accumulated knowledge. Even though this meeting has become a tradition, it also provides a choice venue and important opportunity for our younger colleagues -who have newly begun (or will soon begin) scientific research- to become familiar with our profession and to gain knowledge and experience on a variety of subjects. I sincerely believe that, beyond the goals of emphasizing the importance and quality of international-level earth science investigations being carried out in Turkey, of creating a setting for scientific discussion, and of providing a context for exchange of knowledge, the meeting will be productive and successful as it draws the attention of all segments of our populace, and also national and international organizations, to subjects which concern them; namely, subsurface mineral, water and energy resources, earthquakes and other natural disasters. Once again, I wish to thank you profusely and wish you all fruitful and pleasant scientific sessions, workshops and field trips. I offer sincere affection and kind regards to each of you, thanking you - personally and in the name of the organizing and planning committees- for your significant contributions, with the desire that the colloquium will bear much fruit for the sake of our country and the earth sciences community.
