Mineral Exploration and Alteration Zone Mapping in Eastern Desert of Egypt Using Aster Data
This paper proposes a method to find gold deposits in the Eastern Desert of Egypt. Different methods including various classification methods, principle component transform (PCT), band ratios, and a constrained energy minimization technique are evaluated for their performance for hydrothermal alteration zone mapping. First, these techniques are carried out to highlight known gold deposits over ...
متن کاملAbu Hamamid Neoproterozoic Alaskan-type complex, south Eastern Desert, Egypt
Abu Hamamid (AH) Neoproterozoic (Sm/Nd model age of 770 ± 20 Ma) mafic–ultramafic intrusion lies along a NE–SW fracture zone in the Shadli Metavolcanic Belt, south Eastern Desert, Egypt. AH intrusion is concentrically zoned with cumulate clinopyroxenebearing dunite core mantled by olivine clinopyroxenite, hornblende clinopyroxenite and hornblende gabbroic rim. The observed crystallization seque...
متن کاملApplication of fractal modeling and PCA method for hydrothermal alteration mapping in the Saveh area (Central Iran) based on ASTER multispectral data
The aim of this study is determination and separation of alteration zones using Concentration-Area (C-A) fractal model based on remote sensing data which has been extracted from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images. The studied area is on the SW part of Saveh, 1:250,000 geological map, which is located in Urumieh-Dokhtar magmatic belt, Central Iran. The ...
متن کاملDelineation of hydrothermal alteration Zones for porphyry systems utilizing ASTER data in Jebal barez area, SE Iran
Abstract: The Urumieh-Dokhtar Magmatic Belt (UDMB) is the host of many Iranian Cu porphyry deposits. Southern part of this belt, in the range of geological Jebal barez, has been less investigated because of the mountainous and rough topography and also some security confrontation. Porphyry deposits are associated with hydrothermal alteration zones can be mapped using remote sensing data such as...
متن کاملAdaptive Neuro-Fuzzy Inference System application for hydrothermal alteration mapping using ASTER data
The main problem associated with the traditional approach to image classification for the mapping of hydrothermal alteration is that materials not associated with hydrothermal alteration may be erroneously classified as hydrothermally altered due to the similar spectral properties of altered and unaltered minerals. The major objective of this paper is to investigate the potential of a neuro-fuz...
