The hydrocarbon potentials of the carbonates and siliciclastic rocks forming the continuous Paleozoic successions in Southeast Turkey are well understood. In this study, every aspect of the sequence stratigraphy was investigated and the erosional unconformity surfaces of different origin and transgressive surfaces were defined. In this way, the Paleozoic successions of Southeast Turkey were correlated with the hydrocarbon-producing Paleozoic successions of Saudi Arabia. Based on fieldwork, new formations and members were defined and formation boundaries were slightly modified. The stratigraphic sequence extending between the Neoproterozoic igneous basement (Telbesmi Formation) and the Early Ordovician (Konur Formation) is best represented along Zabuk Valley (Derik town). Middle-Late Ordovician successions are exposed between Bedinan (Gurmese) and Yurteri villages, west of Kiziltepe town. The stratigraphic sequence between the Early Silurian (Dadas Formation) and Late Permian-Early Triassic (Gomanibrik Formation) is represented northwest of Hazro town. In these areas, many stratigraphic and sedimentologic sections were measured, and shale and sandstone samples were collected for palynological and petrographic examination to evaluate their reservoir quality. The outcrops and subsurface indicated that the thick Middle Cambrian stromatolitic algal limestone (Koruk Formation) has both source rock and reservoir rock potentials. The glaciogenic Yurteri Formation has deeply incised into the Bedinan Formation. The well-sorted and porous glaciofluvial sandstones produce oil and gas in southeast Turkey and other countries located on the Gondwana continent. The organic rich shale deposited at the base of the Silurian Dadas Formation forms a very productive source rock for the entire Paleozoic successions. Crude oil has been produced from the Late Silurian Hazro sandstone. In order to locate exploration wells in the right place, depositional environment models of all the formations, their lithofacies, isopach maps and hydrocarbon migration pathways were prepared. This is crucial for geological exploration and oil and gas production.

The Etyemez coal field in the Kangal Neogene basin is an intra-cratonic basin, located south of Sivas (Central Turkey), was filled with continental sedimentary sequence, and contains important coal deposits with approximately 500 million short tons lignite reserves. This basin is surrounded by the sedimentary and ophiolithic pre-Neogene basement rocks and it contains several lignite deposits, particularly Etyemez and Kalburçayırı sites. This study was performed to investigate the underground structure, geological features and potential of the lignite deposits. In addition to, the growth fault effect on coal thickness and quality, tectonic-sedimentary evolution of the coal basin are other important goals of this present study. NE-trending normal fault systems have developed in marginal parts of the basin and influenced the thickness and distribution of the coal bearing Neogene sediments. These syn-sedimentary growth faults have controlled the thickness of the Neogene overburden sediments and coal seams in a lateral direction. [Received: March 3, 2014; Accepted: November 11, 2014]

The Fethiye-Burdur fault zone is not a single line. Still, it consists of discontinuous northeasterly trending fault segments developed parallel to each other between the Gulf of Fethiye and Burdur Lake. The NE-trending and leftlateral oblique-slip Fethiye-Burdur fault zone bounds the Isparta Angle to the west and is probably a continuation of the Pliny fault zone of the Hellenic arc. Year 1914, 1957, and 1971 earthquakes occurred in the Fethiye-Burdur fault zone, with magnitudes of 7.1, 7.0, and 6.1, respectively. The epicenter distribution of the earthquakes of the last century indicates the continuation of the Fethiye- Burdur fault zone under the Gulf of Fethiye, probably to Rhodos Island. According to GPS measurements, the Fethiye-Burdur fault zone is the southern limit of the Aegean extensional region. The Aegean region is characterized by coherent motion toward the SW at 30 mm/yr relative to the Eurasian plate. Field observations and fault plane solutions of recent earthquakes in and around the Burdur Lake region reflect normal and left-lateral oblique faulting considering the NE extension of the fault zone. According to the proposed kinematic model, the different seismotectonic behaviors of the Fethiye-Burdur fault zone originate in the rigid influence of Yeşilova peridotite massif of the Lycian nappes that occur to the SW of Burdur Lake. The kinematic interactions between the mainly NE-trending enechelon fault constituents of the Fethiye-Burdur fault zone result in different seismotectonic characteristics. Consequently, a new kinematic model is obtained for Burdur Lake and its surroundings.
