Çaltı Çayı Yukarı Havzası’nın (Kangal Doğusu) Jeomorfolojisi

Abstract

Research area include the Upper Basin of Çaltı Stream which is the one of the important branches of Fırat in the east of Uzunyayla Plateau which constitutes one of the important Neogen basins in Turkey. Uzunyayla Plateau which is a geological basin, has been divided in two parts as a morphological unit. The west part of this Plateau constitutes Uzunyayla Basin and the east part constitutes Kangal Basin. The limitation of reverse fault from North and South caused the construction of intra mountaine basin. This basin is the research area which locates in the east of Kangal Basin. The research area which is affected by the pressure regime in strike of N-S has rised, continuously. Rising depends on thrusts. This condition had been effective until early Pliocene. For this reason, neo-tectonic started in Pliocene. The basin had indicated the characteristics of sedimentation area during Upper Miocene-Pliocene. There are lacustrine and river formation in Basin. The thicknesses of these formations are approximately 200 m. Erosional surfaces developed at specific heights in highland at the North and the South, according to base-level of the Basin in different periods. Highlands were sliced by left lateral faults in the strike of NE-SW. These faults were cut by the secondary right lateral faults in the strike of NW-SE. Upper Basin of Çatlı Stream is a structural Plateau which is approximately 1650 m in height formed by splitting cores on horizontal structure. Geomorphological units can be seen in curled, faulty, horizontal and monoclinal structure at the Basin. Typical structur plateau, cornish and mesa are formed by splitting cores. Offset ridge and valley, fault scarps, sag-pont, triangular facets, thermal sources and mass movements had developed throughout faults
