Application of Remote sensing techniques in discrimination of rock units and preliminary assessment of tectonic activity using ASTER and ALOSE-PALSAR data at Gabal Delihimmi, Central Eastern Desert, Egypt

Abstract

HE CURRENT study examines the validity of remote sensing and tectonic geomorphology techniques in delineating different lithologies and inferring the relative tectonic activity in arid areas. Principle Component Analysis, spectral Band Ratioing, and Minimum Noise Fraction Analysis were applied using the satellite ASTER data of Gabal Delihimmi area in Central Eastern Desert of Egypt. Additionally, mountain front sinuosity and valley floor width to valley height ratio as two major geomorphic indices were extracted and calculated from the ALOSE-PALSAR digital elevation
