ABSTRACT: The Kuh-e Siah anticline
is located in the Sarvestan area of the Fars province (186 km to Persian Gulf)
and Interior Fars sub basin. This anticline is a fault bend fold and is located
in the Sarvestan fault zone with Northwest-Southeast trend. The Sarvestan fault
zone has caused main deformation by dextral strike slip activity in southern
part of the Zagros fold-thrust belt. The main aim of this paper is to determine
of fold style elements and folding pattern of the Kuh-e Siah anticline. This paper presents part of the
results of a regional study of the Fars province in the Zagros Simply folded
belt, based on original fieldwork, satellite images, structural sections,
geological maps and well data. In addition, we used some software as Global
Mapper and Tectonics FP for prepared some data. Folds, which are close
sideways, are neutral and these require special attention. It is remarkable
that, in all sections of the Kuh-e Siah anticline, fold type is close and in
the middle part of the anticline, fold type is different with other parts. In
the middle part, fold type is upright-moderately gently plunging. On the other
hand, in northwestern and southeastern parts fold type is similar together.
These results maybe show that fold style follow that fold sigmoidal shape that
created with two-fault segment of the Sarvestan fault zone in the study area.
Therefore, it seems that the Kuh-e Siah anticline has suffered high deformation
in the Sarvestan fault zone and this fault zone has created shear zone.
