Subsurface Analytical Methods For identification basementStrike-slip Fault in Ahvaz Field

Category Tectonic & Seismotectonic
Group GSI.IR
Location 21th symposium on geosciences
Holding Date 24 May 2008

Abstract:
      In a fold cross section, a plan that has equal distances from every limbs, spilits the fold angle and cuts the every fold layers hinge (every layer most flexure point) named ?Fold Axis Surface? and it cuts the hinge zone across the ?Fold Axis?.
   Many methods established to determine a true axis of Ahwaz Anticline, some of them are:
   Inscribed Circles Analysis, second derivative manipulations of structural maps key bed deformation analysis, regional morphologic analysis of subsurface structures (in horizons of Asmari and Sarvak formations) and Surface Analysis.
   Finally, based on these methods, a probable basement strike-slip fault identified. In which its strike is N15?E and has been displayed 2 Km through the folding of Asmari Formation. On the base of geophysical data and deformation of Ahwaz Sandstone member, this fault has effected Asmari formation by a shear zone with no detachment planes.

   Finally, based on these methods, a probable basement strike-slip fault identified. In which its strike is N150E and has been displayed 2 km through the folding of Asmari Formation. On the base of geophysical data and deformation of Ahwaz Sandstone member, this fault has eddected Asmari formation by a shear zone with no detachment planes.
