One of the major strengths of a Geographic Information System (GIS) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. These capabilities make GIS an extremely useful tool for mineral exploration. Several spatial modeling techniques can be employed to produce potential maps. However, these...

Frequency is a key physical parameter in potential field theory. Accordingly, Fourier transforms play an important role in aeromagnetic processing and many common enhancements are efficiently implemented in the Fourier domain. However, the trade-off for accurately measuring the frequency content of a signal is a complete absence of spatial localisation in the Fourier domain. Fourier-based enhan...
Egypt’s mineral resources are an effective means of raising the country’s income. Consequently, searching for deep subsurface ore deposits is essential. In this study, we map structure and occurrence related gold-ore mineralization in ophiolitic-assemblage rocks around Wadi El-Saqia area Central Eastern Desert Egypt. Our approach combines airborne geophysical data (aeromagnetic mapping) geochem...

Abstract Geothermal energy potential is identified through the deep investigation of geological, geothermal, and geophysical information over a small area; however, this task both expensive complex. Geographic Information Systems (GIS) can integrate different types data (or thematic layers) large regions use them to identify zones high geothermal potential. In study, we GIS as tool construct fi...

Basin-and-range geothermal resources are typically fault-controlled, deep-circulation systems. They commonly occur beneath thick sequences of Tertiary and Quaternary basin-fill sediments which hinder understanding of fault geometries and faulting patterns. Recent experience at Dixie Valley and survey of the literature for other systems suggest a low-cost and rapid exploration strategy for estab...
