Abstract: (2496 Views)
The Dara anticline as one of the anticlinal oil structures in the Zagros fold-and-thrust belt within the Dezfol embayment (west of the Kazerun fault) has been carried out at this research. For this aim, after the determination of fold trend and mechanism, some sections at: NW nose, center and SE nose of anticline have been drown by using subsurface data. Analyses of folds exhibit the Dara anticline at Class 3 Ramsay classification. On the base of Fleuty classification, this fold is an open one. Fractures are at three main trends: E-W, N-S and NW-SE. Restoration sections indicate that the rate of shortening along the NW nose (A-A' section) is 6.5% and at B-B' section is 8.4% that illustrates on high folding rate at SE nose of the Dara anticline.
