- ALTERNATIVE ENERGY RESOURCES
Kadir GÜRGEY – Near East University, TRNC
İsmail BAHTİYAR – Turkish Petroleum
Hasan Armağan DERMAN – Turkish Petroleum
Dear Geoscientists, when we talk about alternative energy sources, for sure, we think about alternatives to fossil fuels. However, increase in energy demand, huge gap between energy supply coming from alternative energy resources like renewables and energy demand, did not reduce the dependency on fossil fuels. For this reason, to access fossil fuels, use of technologies for energy production seem inevitable in the future. The use of new technologies other than the conventional methods are crucial. In this session, not only alternative to fossil fuels will be discussed but also, innovative/alternative technologies used to exploit fossil resources will be covered. We are expecting your unique studies on the following subjects:
- Shale Oil/Gas exploration, exploitation and production
- Industrial Application Projects for Natural Gas Hydrates in Methane Hydrates
- Coal Gasification Projects and Research& Development Projects
- Research& Development Projects on extracting oil equivalent products from Bituminous Shale Reserves
- Scientific and Technical Studies on Hydrogen Technologies and Economics
- Research& Development Projects on Carbon Capture and Storage
- Applications of environmental protection technology in fossil fuel production

- EARTH – ATMOSPHERE INTERACTION
Doğuşhan KILIÇ – Paul Scherrer Institut, Switzerland
Alper ÜNAL – İstanbul Technical University
Fatma ÖZTÜRK – Abant İzzet Baysal University
Layers of atmosphere interact with the Earth and hydrosphere directly or indirectly. This interaction may show up as the decreased average global temperature by a volcano or a significant change in the average annual precipitaion due to the change of the sea surface temperature over a specific region on the ocean (e.g. ENSO). Thus, atmospheric variability, impacts all biota, is driven by determinants such as geography, meteorological conditions, extra-terrestrial determinants and the anthropogenic activity.

All forecasts show that fossil fuels are going to continue to make up a large percentage of total energy consumption in the following decades. However, considering world population growth, and the increase in energy need per person, the contribution made by alternative energy sources will need to increase as a percentage of the total global consumption. When the geography and geology of our country are considered, it has clear potential for the use of alternative energy sources such as solar, wind and geothermal. Recent legislative regulations and incentives have encouraged investigation into and investment in production facilities, which has resulted in an increase in geothermal energy production in our country.
The purpose of this session is to encourage a scientific discussion of the current research results related to topics such as geology, geochemistry and geophysics, with a focus on geothermal energy. This geothermal energy session is open to those participants who share information with stakeholders about the results of direct or indirect utilization applications of geothermal energy by giving oral or poster presentations. We expect the attendance and contribution of Earth scientists who are working on geothermal energy.

Even in different sizes, all human settlements are in a part of nature. For this reason, the historical, cultural and natural environment that provides the continuity of past to the future as well as the surface – underground richness that nature provides, and the macro – micro risk cases that nature has explicit or hidden, must be recognized first and defined with positive – negative characteristics and spreads. All these natural phenomena should be examined considering all possible interactions with existing and possible settlement areas, with the determinations to be made during the planning phase while maximizing the opportunities of the ability to use natural resources on the other hand the probability to meet encountering natural and/or anthropogenic problems that may occur during and after implementation – structuring should be minimized. At this point, local administrations’ level of consciousness and directive decision making mechanisms about the issue are vital importance.
The situation requires “urban geology” studies which applies every kind of information and finding, initially “regional and areal” and later on “local and point”, to planning, structuring, making livable, renewing, and elaborating terrestrial problems of human settlements. In this context, urban geology uses terrestrial data at the making decisions about urban planning – implementing and solving settlement problems, designates site selections, current and possible structuring conditions, renwing situations, new extension areas, and apparent / possible problems of cities and city elements and produces solutions to all natural and anthropogenic origin problems.
The major urban geological studies that should be carried out in the context of creating a city that is planned, developed, lived and renewed, in brief made sustainable by local governments can be summarized under the following main titles as ; terrestrial analysis, terrestrial synthesis, terrestrial planning decisions production, making decisions about site selection for habitation / settlement areas – units, examination of habitation / settlement areas at regional / local planning and practices, examination on suitability for structuring, sustainability studies, structured environmental analysis, reconstruction (recycle – conversion) studies, determination of strategies, areas, and direction of potential urban development.

Bülent ÖZMEN – Gazi University
Turkey is subject to frequent natural disasters such as earthquakes, floods, mass movement, storms, cyclone, drought etc., are often experience. When adequate measures have not been taken, These events turn into disaster and They lead to loss of life and property. Because of disaster, 2-5% of Turkey national income is lost every year. In order to reduce these losses, It is necessary to comprehensive interdisciplinary studies and these studies should be managed effectively. Disaster management can be defined as the organization and management of resources and responsibilities for dealing with all humanitarian aspects of emergencies, in prticular preparedness, response and recovery in order to lessen the impact of disasters. Geoscience has important responsibilities in all phases of disaster management.
The management focused on mitigation of disaster losses should be accomplished only by comprehensive interdisciplinary efforts and the contributions of geologists. For effective and sustainable disaster management, legislation, administrative, technical, and scientific methods should be determined before disaster period. In essence, this approach adopts a risk management approach rather than crisis. In this session, how to ordinary natural phenomena turned into disaster, and mitigation, preparedness, response and recovery efforts, the mission of earthscientists in disasters will be discussed with the valuable presentations of data collected from some regions of Turkey and abroad.
Natural disasters and Disaster management section will be presented all kinds of articles related to natural disasters and disaster mangement.

Osman Parlak – Çukurova University
İbrahim Uysal – Karadeniz Techincal University
Utku Bağcı – Mersin University
Ophiolites, on-land fragments of oceanic lithosphere, are the key to understanding processes involved in the evolution of oceanic basins. Ophiolites display variable internal structure, pseudostratigraphy, geochemical composition and feature in many different orogenic belts of different age. They are interpreted to have formed in a wide range of tectonic settings, including mid-ocean ridge, back-arc and fore-arc. Numerous models exist for oceanic crust generation, metamorphic sole and melange formation, tectonic emplacement and ore genesis.
The aims of this session are to discuss (i) recent scientific advances on ophiolites of Tethyan belt and surroundings, (ii) mantle melting and melt/rock interaction, (iii) metamorphic processes during formation and emplacements and (iv) melange genesis. We warmly welcome a large number of scientists from Turkey, Asia, Europe and America for fruitful discussions on this topic.

Ayten ÇALIK – Çanakkale Onsekiz Mart University
Therefore, gemstones, if they are of good quality, differ from metallic and other industrial minerals and natural building stones because they do not need bulky excavations and large production amounts, even though they have ore of low tenor and small reserves. Gemstones, because of the reasons that can be shortly expressed as beauty and attractiveness emerged from the original physico-chemical properties as well as rarity, are the general definitions for the resultant specially valued mineral (ore), rock and petrified organic material. Gemology covers all scientific and commercial activities related to precious and semi-precious gemstones (such as the geology, mining, lapidary, identification, synthetic production, artificial treatment, mounting to novel metals, marketing, and also archeogemology). However, the economic impact of gemology and related industries has not yet been realized. Hence, “Precious Semi-precious Gemstones Session” of the symposium welcomes the proceeding abstracts of all original research, review and case presentation relating to gemological materials (gem-minerals, gem-rocks and gem-petrified organic formations).
- QUATERNARY STUDIES
Ahmet Evren ERGİNAL – Ardahan University

Yeşim BÜYÜKMERİÇ – Bülent Ecevit University
The Quaternary is the most recent geological period of time in Earth’s history, beginning 2588000 years ago and continuing to the present day. The Quaternary period is characterized by a series of large-scale environmental changes that have profoundly affected and shaped both landscapes and life on Earth. One of the most distinctive features of the Quaternary is to have ongoing consecutive cycles with long lasting glacial stages (build-up of major continental ice sheets and mountain ice caps) and shorter warm episodes (interglacials), of which temperatures were similar to or higher than today. Turkey is situated in between intercontinental basins of the Black, Marmara, Aegean, and Eastern Mediterranean seas with their connecting straits and coasts. The periodic episodes caused the connections and isolations of these basins were repeatedly connected and isolated from each other. Thus, it is very important (1) to reveal Quaternary geological history with the integration of stratigraphic, sedimentological, geochemical, palaeontological, ecological and molecular data to identify the critical environmental conditions and processes involved (2) to focus on paleoenvironmental and paleolandscapes changes (climate, glacials, sea level fluctuation, coastline migration, volcanism, etc.) and (3) to understand human response (archeologhy, paleoantropology, migration, subsistence strategy, physical and cultural adaptation, etc.) to environmental changes. Furthermore, understanding long‐term natural biotic and abiotic drivers of marine, lacustrine and terrestrial systems in the past 2.6 million years will also help to obtain valuable information about the current response of environmental and biodiversity crises to rising natural‐ and human‐induced perturbations.

- REMOTE SENSING AND GIS
Kaan Şevki KAVAK – Cumhuriyet University
Can AYDAY – Eskişehir Anadolu University
Bekir Taner SAN – Akdeniz University
Remote Sensing and Geographic Information Systems are becoming more and more widely used every day due to the equipment that will benefit the understanding and observation of earth sciences in Geological Engineers more effectively. Remote sensing technology and methods have become one of the indispensable tools of earth sciences at a time when the importance of spatial data has increased. Nowadays, these methods have made a great contribution to the creation of geological maps in a controlled manner in large areas. The same methods provide interferometry to detect the horizontal and vertical displacements in the earth’s crust and provide information during the monitoring and evaluation of natural disasters such as earthquakes. In addition to these, in addition to Remote Sensing and Geographical Information Systems, a large number of spatial data can be interpreted in a short time and studies can be made to reveal the mineral zones in the alteration zone. Again with these new technologies and methods, geosciences are able to open up new areas of renewable energy exploration (e.g. wind, solar and geothermal). For these reasons, we invite you to work in the field of remote sensing and geographical information systems, we are inviting you to share in the 71st Turkish Geology Congress together with all of Turkey and look forward to your abstracts.

This session is aimed to provide a platform for understanding the mechanism, kinematics and geodynamic settings of Ayvacık, Lesvos (Mytilini) and Bodrum–Kos (the Gulf of Gökova) earthquakes in the Aegean Sea. It includes utilization of satellite geodesy data (GNSS, InSAR and dense local GPS arrays) to control static and dynamic ground deformation and in combination with seismological and strong motion data to compute finite-fault models. Such models are then used as input for modeling of strong motions, of tsunamis, and of diverse seismological parameters, and for identification of the fault pattern and its geological, geomorphological and seismological implications. Case studies associated with post-tsunami surveys, eyewitness reports, measurements of run-up traces, methods and results of tsunami numerical modeling, assessments with observations and measurements are encouraged. We invite contributions from all multi-disciplinary fields of the Earth Sciences to share their observations and proficiencies for our mutual interests.
