Preliminary Remote Sensing Investigation towards Geological Mapping in Northwest Libya

[ABSTRACT]This stu dy p resents a de tailed analysis based on d igital pro cess of o ptical La ndsat E nhanced Th ematic Mapper Plus (ETM+) and radar (C-band Synthetic Aperture Radar (ERS-2 SAR)) remote sensing data, and digital elevation model (DEM) extracted from topographic maps (1: 50,000) to eval uate their efficiency for geol ogical mapping in the Jifara Plain of northwest Libya. Lithological and structural units were distinguishable based on their topographic form and spectral properties. GIS and remote sensing-based methods were used to integrate all raster a nd v ector resul ts extracted from multiple g eoscientific data types. T he results d iscriminated e ighteen lithological units were p lotted int he・ geological map defined by the new b oundaries. The dominant extracted lineaments tend to run in the NW-SE direction. Analysis and interpretation of the extracted lineaments provided information about the tectonic evolution of the study area. Field work was done for ground-based verification of remote sensing data.
