Geometric Analysis of the Buneh Kuh Anticline (Zagros)

The Buneh Kuh anticline (with 25 km length and 7 to 17 km width) is a NW-SE trending anticline in the Coastal Fars Sub-basin (Zagros simple folded belt). Gachsaran formation is cropping out in the core of this anticline. In this paper the elements of fold style and folding mechanism have been investigated in the Buneh Kuh anticline. It is an asymmetric detachment fold on the Hormoz Formation. Herang anticline is a NW continuation of the Buneh Kuh anticline. Sub-surface contour map on the top of the Dehram group (gas reservoir) was prepared and its western culmination (near to the DD' cross section) could be recommended for drilling.
