Arabia-Eurasia convergence is achieved in the NW Zagros by a combination
of shortening on NW-SE- trending folds and thrusts, mainly in the Zagros
Structural Belt, and by right-lateral strike-slip on the NW-SE-trending
Main Recent Fault.The contrast stretched of ETM band 4 was found to be
the best in displaying lineaments and folds for the area, hence was
further processed by using directional filters and generated different
combinations of False Color Composites.Finally a structural map of the
study area has been prepared using the processed ETM images.This study
indicates that the Landsat ETM data is useful for locating and
interpretation of the structural features in the Zagros Structural
Belt.Study on the Landsat ETM, images combined to field visits reveals
that the area is highly active and structurally is in dynamic state due
to compression forces. However the density of the structural features on
the imagery calibrated to several filed visit data shows that the south
and southeast of the study area are not as tectonically active that may
be due to presence of thick evaporite sequence of Gachsaran Formation on
the Landsat image.
