ABSTRACT: Folds have a significant
development in the Cretaceous-Tertiary rock units of the northern part of
Bagheran Mountains in southwest Birjand between Lut and Sistan structural
zones. The general trends of fold axis and axial surface are E-W and the folds
are less exposed by distance from mountain and plain boundary. Geometric and
kinematic status investigation of folds (such as f2 fold in the middle part)
and faults shows that faulting process has created some of the folds leading to
their development. Such structures are described as fault-related folds. Also,
analysis of geometry and mechanism of faults indicate that back thrusts have
the largest influence on generation and development of folds in this region.
