Study of a Geological Structure Using Remote Sensing Technology for The Regions of Fukha' and Temsa in South Central of Libya

Abstract

This study is based on the use of remote sensing technology for satellite imagery to study the geological structures in the south central Libya region (Fuqaha'). In this study, some of the satellite images of Landsat 7 for the study area, and the geological structures and linear manifestations of the area were explained. The manual mapping of the studied area is done, which is one of the primary methods of mapping. Geological maps were prepared for the studied area. The study of the area indicated that it contains many faults and fractures. The direction, lengths, angles, and ages were determined and the diagram was prepared by Rose Diagram. Then drainage of valleys and some folds and stratigraphy of the region and other geological features were determined. The study showed that most of the probable and confirmed Faults and Fractures in the Fuqaha' area take directions (northwest-southeast to east-west) and for the Temsa area they take directions (northeast-southwest and northwest-southeast). It is clear from this mapping that most of the sedimentary rocks of the region, except for some areas, contain Igneous Rocks as a result of basalt flows due to the tectonic movements in the region which caused the weakness of the crustal rocks. These are believed to be the cause of the Black Herring
