Petrografik olarak takilit veya impaktit şeklinde adlandırılan çok özel taneler, içine yerleştiği istifin alt-orta bölümünde olup, bulunduğu alandaki toplam çakıl miktarının yaklaşık % 1-1,5 kadarını oluşturur. Bu takilit parçaları ve/veya metamorfik kaya kırıntıları büyük bir çarpma kraterinin aşınıp dağılan parçaları olup, Geç Miyosen öncesi bir zamanda orta Anadolu'ya asteroid düşmesinin işaretçileridir. Takilit tiplerine ve bolluğuna göre, çarpma kraterinin minimum 2 km çapında ve 200 m derinliğinde dairesel bir çukur olduğu anlaşılmaktadır. Böyle büyük bir çarpmanın yarattığı olası paleoekolojik ve paleocoğrafik etkiler araştırılmaktadır. ABSTRACT It is presented here some unusual brecciated rock clasts within the clastic deposits of the Late Miocene and Pliocene at the Mucur (Kırşehir) area of central Anatolia, Turkey. Petrographycally, these clasts are described as tachylite or impactite. They are dark-coloured metamorphic rock fragments with size of 100 to 3-4 cm in diameter, which are abundantly breccaited and to a lesser extend melted-rock fragments embedded in thick silica layers. The tachylite clasts are found only at the lower and medial part of the Late Neogene sequence, forming only 1-1.5 % of the total clast components of the host deposits. These special clasts (tachylite or impactite) represent the destroyed walls of an impact crater created by an asteroid at central Anatolia in preLate Miocene time. Based on tachylite types and their abundance, the inferred impact crater was a circular depression with minimum 200 m depth and 2 km in diameter. The possible palaeogeographic and palaeoecological results of such a big impact to the earth have been searched.

Over the past 21 years, the southern region of Turkey has undergone more significant land-cover change than any other regions. The extent of these changes is remarkable, especially over the last years, during which time much of the area has been exploited in Kumluca District as greenhouse zone. In this paper, Landsat (Land Satellite), Aster (Advanced Spaceborne Thermal Emission and Reflection Radiometer), Spot (Satellite Pour l'Observation de la Terre), satellite images have been used to expose existing land-cover changes. Among the mentioned changes, those relating the extension and development of greenhouse zone have affected obviously the socioeconomic and demographic structure of the Antalya-Kumluca District. In addition, day by day natural land are being converted to build-up (Settlements, Roads, Tourism Facilities, Water Reservoirs, etc…) and greenhouse area. According to different satellite images and maps of the years between 1990-2011, greenhouse area covered almost 70-80 percent of the study area.

For this purpose, related conceptual framework was analyzed, covering related sewage characteristics, soluble microbial products generation, and substrate solubilization and leakage due to hydrolysis. Soluble COD footprint was experimentally established for a selected treatment plant, including all the key steps in the sequence of wastewater treatment and sludge handling. Observed results were compared with reported DOCs in other treatment configurations. None of the leakage tests performed or considered in the study could even come close to the prescribed limitation. All observed results reflected 10-20 fold higher DOC levels than the numerical limit of 800 mg/kg (80 mg/L), providing conclusive evidence that the DOC limitation imposed on municipal treatment sludge for landfilling is not attainable, and therefore not justifiable on the basis of currently available technology.
