Author(s):
Abstract:
West Guilan drift with more than llo kms of length along north-west, south east direction is located at the south west part of Kermanshah province. In this study, techtonic and morphologic issues of the areas located in the path of west Guilan drift at the south west wing of Ghalaje anticline have been studied. Geomorphic indices and geomorphologic have been used for evaluating the activeness of west Guilan drift. In this study, topographic quantities (Smf, Fmf, Fd, Eu, Sl) and indices of drainage network modle (Af, T) have been used as the main tool. Also, geomorphologic evidences obtained from west Guilan drift, earthquake data and geological evidences have been used. The main purpose of this study is to investigate the activeness of west Guilan drift. The result of the study shows that west Guilan drift has been active with in Peliyo-Quarternary period and with respect to the earthquake occurance along its direction, it is also active in the present time (Holocene). Analysis of topographic quantities indicates the continuing of active rising in the region.
