The work was undertaken to provide a basis for detailed planning and execution of a regional mineral exploration programme that is being conducted by the Egypt-Sudan Integration Project and was initially assisted by the UNDP. This paper describes the main geological and mineral exploration results and the interpretability of the satellite imagery.

In this regard, it discusses in detail the various genetic mineralization styles in the ANS including: (1) magmatic mineral deposits associated with mafic-ultramafic rocks (e.g. chromite, Ni-Cu-Co-PGE magmatic sulfides, Fe-Ti-V oxides), (2) intrusion-related (magmatic-hydrothermal) deposits associated with felsic to intermediate rocks (porphyry ...

Sudan by the geological Research Authority of Sudan making use of satellite images. Band ratio technique was applied to Arbaat area and a signature of alteration zone was detected.

Satellite processed images were used to identify the main features regionally associated with the Quaternary deposits. Using Electrical Resistivity Tomography (ERT) survey for mineral exploration is feasible in the current study because the ground conditions of the study area are favorable for carrying out the geophysical …

Satellite systems have long been used to investigate mineral deposits. While work has been conducted in mapping remote deposits or types of minerals that are harder to quantify, such as from clays, recent work has also shown that minerals that move around, due to wind erosion, could have also important consequence for the planet.

These methods have helped to discover many minerals deposits around the world, such as gold deposits (Gossanic ridges) in Red Sea hills of NE Sudan using Landsat 8 OLI …

Spectral signatures acquired from satellite images, on the other hand, could be used to study mineral deposits. As a result, this study proposes a method that takes advantage of both domains.

Today, its estimated mineral deposits include at least 700,000 tons of chrome, 160 tons of gold, 100,000 tons of manganese, and smaller amounts of asbestos, talc, gypsum, kaolin, and magnesite. South Sudan's mineral deposits include substantial quantities of gold, copper, lead, zinc, and nickel and marble.

The study area is located in North Kordofan State, central Sudan at approximately 990 km from Khartoum, the capital. It is situated between latitudes: 13° 36′ 00" and 14° 00′ 00" N; and longitudes: 27° 55′ 07" and 28° 38′ 11" E (Fig. 1 a).It extends over two climate belts, corresponding to the two major E–W trending climatic zones in …

A series of robust image processing algorithms was implemented for detecting spatial distribution of pixels/sub-pixels related to key alteration mineral assemblages and structural features that ...

3.6 Magmatic Mineral Deposits in Sudan ... The results from satellite image analysis and monitoring showed that sand dunes along with heavy rains and fooding are the main decay factors, causing ...

existence of iron mineralization in the study area. The iron ore as revealed by the satellite image is quite prospective; however, detailed ground geological survey is needed in …

Satellite image analysis to detect mineral occurrences in areas with thick vegetation cover; ... The effectiveness of the vegetation index (VI) for identifying mineral deposits was demonstrated by the case study of the kuroko deposits in the Hokuroku district, northern Japan. Vegetation anomalies were detectable though a sequence of …

This introduction has highlighted the science and technology of using satellite images in mineral exploration. Satellite images are ideal for early exploration in arid regions with sparse vegetation, and make an ideal first data package when combined with field mapping and geophysics. The subject of remote sensing is massive and I've …

Other options include KOMPSAT-3 and KOMPSAT-3A, operated by the Korea Aerospace Research Institute, which provides high-resolution satellite imagery over Sudan with a spatial resolution of up to 38 centimeters, and the Satellogic Aleph-1 constellation of satellites has developed a unique way to improve the spatial resolution of their …
