Study area, the Eskipazar Basin, is located in the western part of the North Anatolian Fault System. It is a 3-5 km wide, 10 km long and NWSE trending depression, bounded by a complex array of oblique-slip normal faults and strike-slip faults. The Eskipazar Basin is interpreted to be a superimposed basin. The basin fill is composed of two different units deposited under the control of different tectonic regimes, namely the paleotectonic and the neotectonic regimes. The latest paleotectonic fill of the basin is the fluvio-lacustrine deposits of the paleotectonic Eskipazar formation. This formation is unconformably overlain by a group of neotectonic units namely, the Budaklar, the Karkin and the imanlar formations. The unconformity in between these paleotectonic and neotectonic units represents the time interval during which the paleotectonic period comes to end and the neotectonic period started. Thus, onset age of the strike-slip neotectonic regime in the study area is Late Pliocene (&amp / #8764 / 2.6 My). Common basin margin-bounding faults of the Eskipazar Basin are the Kadilar fault set, the Beytarla Fault Zone, the Budaklar fault set, the Arslanlar fault set, the Dibek fault, the Karkin fault, the Boztepe fault and the Acisu fault. These faults display well preserved fault scarps, in places. Morphological expressions of these faults and their geometrical relationships to regional stress system indicate that these faults are mostlystrike-slip faults with normal component. However the Kadilar fault set displays a different characteristic, being the major fault controlling the basin to the west and it is indeed an oblique slip normal fault. Long term seismicity and their epicentral distribution in and very close to the study area suggest that the Eskipazar basin is located in an area of seismic quiescence, nevertheless the morphotectonic expressions of the faults exposing in the basin suggest that these faults are active. Since the most of settlements are located on different lithologies of poorly consolidated deposits of the Eskipazar formation susceptible to landslides, the area is open to future earthquake hazard. Therefore, structures and settlements have to be constructed on strong ground away from active faults.

Study area, the Yeni&ccedil / aga Basin, is located in the western part of the North Anatolian Fault System. It is a 1-5-km-wide and 14-km-long WSWENE- trending depression bounded by a complex array of strike-slip faults. The Yeni&ccedil / aga Basin is interpreted to be a fault &ndash / wedge basin with the North Anatolian Fault&rsquo / s System Master Strand, namely the Gerede Fault, cutting across the basin itself. The basin and its surroundings contain mainly two groups of rock units namely the paleotectonic units and the neotectonic units. Paleotectonic units, which are deposited or formed during different phase(s) of tectonic regimes, comprise several formations. The most important one of these formations is the Upper Miocene &ndash / Lower Pliocene Eskipazar formation which plays an important role in understanding the evolutionary history of the basin. Neotectonic unit deposited under the control of today&rsquo / s tectonic regime is the Plio-Quaternary Betem&uuml / rl&uuml / formation.v Betem&uuml / rl&uuml / formation unconformably overlies the paleotectonic Eskipazar formation throughout the study area and the unconformity separating these two units corresponds to the time interval during which the paleotectonic stress regime changed into the neotectonic stress regime. Thus, onset age of the strike-slip neotectonic regime in the study area is Late Pliocene (~ 2,6 My). Common basin margin-bounding faults of the Yeni&ccedil / aga Basin are, the ASagi Kuldan fault, the Aksu fault, the izmirli fault set, the Saray&ccedil / ali fault, the Degirmen fault set and the Hamzabey fault set. They display well-preserved fault scarps in places. Morphological expressions of these faults and their geometrical relationships with the local stress regime indicate that these faults are mainly strike-slip and oblique-slip faults. Morphotectonic expressions of the faults exposing within the study area indicate that these faults are active. Most of the settlements within the study area are located on water-saturated loose basin fill nearby the active faults. Hence, these are open to future earthquake hazards. Therefore, structures and settlements have to be constructed on strong grounds away from the active faults.

&Ccedil / i&ccedil / ekdagi basin developed on the Central Anatolian Crystalline Complex (CACC) is a foreland basin developed as the southern integral part of the &Ccedil / ankiri Basin during the Late Paleocene to middle Oligocene. The basin has two compartments separated by the &Ccedil / i&ccedil / ekdagi High comprises two sedimentary cycles. The oldest cycle comprises Barakli, Koca&ccedil / ay and Bogazk&ouml / y formationsa and is exposed both in the northern and the southern sectors. They were deposited in marine conditions. The second cycle comprises incik and G&uuml / vendik formations and was deposited in continental settings. The first cycle comprises uniformly south-directed paleocurrent directions in both the northern and southern sectors whereas the second cycle deposits are represented by south-directed directions in the southern sector, and bimodal directions in the northern sector. In addition, the second cycle formations contain progressive unconformities and coarsening upwards sequences indicative of thrusting. Internal structures of the units and paleostress data indicate that the basin experienced over-all compression and local extension due to flexural bending. This gave way to inversion of some of the normal faults and uplift of the &Ccedil / i&ccedil / ekdagi High during the deposition of second cycle in the Late Eocene to middle Oligocene time which subsequently resulted in compartmentalization of the basin.

A wide range of organic compounds are released from building and furnishing products and these have the potential to adversely affect indoor air quality. There are growing international requirements for testing and controlling these emissions for the protection of public health. The test methods require specialist analytical chemistry facilities based on thermal desorption/gas chromatography/mass spectrometry (TD/GC/MS). This project has addressed the need for better performance and greater automation of the analysis, as well as development of simpler screening tests. A variety of products were tested using screening techniques, with an emission cell method being used as a reference test. Short duration tests, using a micro-scale chamber at slightly elevated temperature, were shown to have the potential to predict emissions occurring during longer term reference tests. Multi-sorbent air sampling tubes, that have the potential to extend the volatility range of compounds determined by a single TD/GC/MS analysis, were compared with Tenax TA tubes specified by current standard methods. This showed no difference in performance for the range of compounds for which Tenax is optimal, with improved performance for a number of more volatile compounds. The determination of formaldehyde was investigated using 2-hydroxymethylpiperidine as a derivatising agent, followed by TD/GC/MS. The results showed the possibility of this method being developed as an alternative to the current standard method that involves solvent elution and liquid chromatography. The performance of a newly developed time-of-flight mass spectrometer was compared with a standard quadrupole instrument. This showed its potential, with the use of re-collection, to extend the concentration range of compounds quantified from a single air sample, of particular benefit for the determination of carcinogens. New compound identification software was applied to increase automation of analysis of the TD/GC/MS data. Good correlation with manual processing was achieved, demonstrating the possibility of routine application to material emissions testing.

Study area, the UruS province, is located 70 km WNW of city of Ankara. Major settlements in the study area are two counties, UruS and G&uuml / d&uuml / l / and there are a number of villages, such as, from W to E, Macun, Yogunpelit, Kabaca, &Uuml / regil, &Ouml / zk&ouml / y, Tahtaci&ouml / rencik, Kirkkavak, Kavak&ouml / z&uuml / , Kayi and Karaca&ouml / ren. The study area is 189 km2 in size and included in 1/25000-scaled topographic quadrangles of H28a3, a4, d1 and d2. The G&uuml / d&uuml / l- UruS section of the &Ccedil / eltik&ccedil / i morphotectonic depression (&Ccedil / eltik&ccedil / i Basin) drained by the Antecedent Kirmir River and its second-order drainage system was first mapped in detail in the present study, and faults determining northern margin of the &Ccedil / eltik&ccedil / i depression were named as the UruS fault set comprising the SW part of the &Ccedil / eltik&ccedil / i Fault Zone / and the mechanism of the master fault of the UruS fault set was determined as left lateral oblique-slip fault with reverse component by the morphologic markers such as the deformed drainage system and pressure ridges. This was also supported by the fault plane solutions of the 2000.08.22 UruS earthquake. Three fault plane solutions, of which two of them for the 2000.08.22 UruS earthquake, and one of them for the 2003.02.27 &Ccedil / amlidere earthquake, were done to determine nature of the source. Ground material underlying the city of Ankara were divided into three categories: (a) well-lithified basement rocks, (b) Pliocene fluvio-lacustrine v sedimentary sequence, and (c) unconsolidated terrace and alluvial sediments of Quaternary age. Quaternary unconsolidated sediments are densely populated in Ankara. These sediments are fine-grained and have a maximum thickness of 200 m or more. Inside these sediments, static ground water level is very close (as on average: 6 m) to ground surface. These conditions are quite suitable for liquefaction of these unconsolidated alluvial sediments. In addition, basement rocks are full of zone of weakness. Even if, the city of Ankara is characterized by the shallow focus and small earthquakes (M&amp / #8804 / 5), it is open to the risk of large earthquakes to be sourced from the North Anatolian Fault System and the Seyfe Fault Zone located 110 km and 80 km, respectively, owing the ground material conditions beneath the city of Ankara. This point has to be taken out in constructions and site selection solution.

The geometry, deformation mechanism and kinematics of the S&uuml / rg&uuml / Fault Zone is investigated by using remotely sensed data including Landsat TM and ASTER imagery combined with SRTM, and stereo-aerial photographs. They are used to extract information related to regional lineaments and tectono-morphological characteristics of the SFZ. Various image processing and enhancement techniques including contrast enhancement, PCA, DS and color composites are applied on the imagery and three different approaches including manual, semi automatic and automatic lineament extraction methods are followed. Then the lineaments obtained from ASTER and Landsat imagery using manual and automatic methods are overlaid to produce a final lineaments map. The results have indicated that, the total number and length of the lineaments obtained from automatic is more than other methods while the percentages of overlapping lineaments for the manual method is more than the automatic method which indicate that the lineaments from automatic method does not discriminate man made features which result more lineaments and less overlapping ratio with respect to final map. It is revealed from the detail analysis that, the SFZ displays characteristic deformation patterns of strike-slip faults, such as pressure ridges, linear fault controlled valleys, deflected stream courses, rotated blocks and juxtaposition of stratigraphical horizons in macroscopic scale. In addition to these, kinematic analyses carried out using fault slip data indicated that the S&uuml / rg&uuml / Fault Zone is dextral strike-slip fault zone with a reverse component of slip and cumulative displacement along the fault is more than 2 km.
