Morphometric analysis of hava and khesht anticlines and their relationship with active tectonics in Fars Zagris

Active tectonics is one of the most important topics that has been discussed in earth scinces field in recent decades. Due to the shortage of historical and instrumental sesimology information in different parts of the world especially in Iran, the necessity of country’s researchers and managers familiarity with active tectonics and reconnaissance of tectonically active regions seems to be obvious. The aim of this study is to evaluate morphometry of Khesht and Hava anticlines and its relation to tectonics active of region. To achieve the above objectives, the necessary data were extracted from1/50000 topographic and 1/100000 geological maps as well as from Landsat satellite images. Also The field studies of geomorphic forms and processes were conducted. The required data for estimaiting geomorphological indices such as Fold Symmetry index, mountain front sinuosity, crest length, aspect ratio, bifurcation ratio, drainage density, stream frequency, drainage texture, texture ratio, Drainage patterns, after importing to GIS software, were evaluated. In general, estimated quantitative indices and qualitative evaluation show that studied anticlines are tectonics activity and laterally growing.
