Geological, geomorphological and structural characterization features of Al Bordi area, Libya

Abstract

This study has been conducted on Al Bordy area, which lies between latitudes N31°48'16.51 N31°43'14.91and E25°00'18.09 E25°06'55.07 on the sea coast of eastern Libya, The area has specified geological features, where the different rock formation exhibit good exposures that give a clear view about the stratigraphic column. The exposed formations are Al Gaghbub, Al Faidiyah and Al Khowaymat. The target of study is to evaluate some characterization features e.g. lithology, stratigraphic analysis, fossil distribution, structural and tectonic setting. The technical simulation models and geographic information system (GIS) software have been applied to interpret some geologic structures such as faulting, fractures, cracks and folding as well as the effect of stresses on formation strata. The field observations and the obtained data revealed that the area has affected by variable geological factors and changes in depositional environments, in addition to tectonic movements that led to the formation of various structures such as anticline and syncline folds, normal faults and unconformities
