摘要：
This research study aims at utilizing the ASTER data for lithological mapping of the Fawakhir area, Central Eastern Desert of Egypt. Short wave infrared and thermal infrared channels were processed and interpreted for the potential mapping of the various rock types at the Fawakhir area. A newly developed ASTER band-ratio of 4/7, 4/10, 4/11 is introduced to characterize the lithological units in the area of study. Field visits and laboratory microscopic examinations of selected samples collected from the different exposed rocks in the area of study were carried out. The validation mechanism was based on both calculating statistical optimum index factor (OIF) and matching interpreted lithological boundaries to field data and previously published geologic maps.
