Abstract :
Zagros Fold-Thrust Belt consists of several fault–related folds which important hydrocarbon reservoirs are formed in relation to their evolution. Understanding of fold geometry and its growth pattern are affective parameters in the exploration and drilling programs of hydrocarbon reservoirs. In this research, stream bed erosion pattern and quantitative morphometric indices were used as geomorphic indicators to recognition the mechanism of fold-growth. Results of geomorphic investigation reveal dominant of detachment folding pattern in the coastal Fars area. Moreover, the effect of change in the thickness of detachment horizon on the folding pattern was evaluated.
