[Termes IGN] signature spectraleRésumé : (auteur) This article examined the spectral interference by heavy metal on the spectral signal of moisture content of heavy metal contaminated soils. Soil samples were collected from an abandoned mine area, and the chemical analysis revealed extremely high contamination amount of copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), and lead (Pb). The mineralogical analysis showed that the spectral signature of the heavy metal contaminated soils was manifested by secondary minerals. Water content suppressed the spectral reflectance of the soil samples but increased the absorption depths. Although a regression model can predict moisture content using the magnitude of the water absorption feature, the accuracy was much lower when the heavy metal concentration was extremely high. It indicates that geochemical reactions between the heavy metal cation and iron oxide/clay minerals may have affected the spectral responses of the contaminated soils at the water absorption bands. Our model also showed that there was a shift of the absorption features of moisture content if the heavy metal contamination level went up. Unlike normal soils, the absorption features of clay minerals and ferric iron were not able to accurately predict moisture in highly contaminated soils. Given the fact that the spectral bands selected in this article were associated with water absorption, the findings from this article may only be useful to a drone-based low-altitude remote sensing of soil moisture content.

[Termes IGN] rayonnement proche infrarougeRésumé : (auteur) The Shahr-e-Babak region located in the Kerman metallogenic belt is one of the high potential segments of Urumieh–Dokhtar magmatic arc for porphyry copper and epithermal gold mineralization in the south of Iran. This high potential zone encompasses several porphyry copper deposits under exploitation, development and exploration stages. The aim of this study is to evaluate Landsat-8 data and comparison with the Advanced Spaceborne Thermal Emission and Reflection Radiometer data-sets for mapping hydrothermal alteration zones related to Cenozoic magmatic intrusions in Shahr-e-Babak region. Previous studies have proven the robust application of ASTER in lithological mapping and mineral exploration; nonetheless, the Landsat-8 data have high capability to map and detect hydrothermal alteration zones associated with porphyry copper and epithermal gold mineralization. In this investigation, several band combinations and multiplications, developed selective principal component analysis and image transformations were developed for discriminating hydrothermal alteration zones associated with porphyry copper mineralization using Landsat-8 data.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Irregularity of geological variables over adjacent rock units makes the standardization and continuity of base metal spatial distribution uncertain. Previous approaches to predict preferable locations of minerale occurence had often been based on systematic data-grid-network sampling. The St.Catherine region in south Sinai has moderate deposits of sulphide mineralization. Comprehensive studies of sulphide mineralization found in the area provide evidence that this mineralization is controlled by three factors : (1) base-metal concentration distribution, (2) structure alteration and (3) intensity. Variables of each controlling factor have been represented by vector layers and then integrated and analysed using a geographic information system to produce mineral potential maps for the study area. Variables of each controlling factor were analysed for each rock type individually. This approach was used to overcome problems due to the geochemical irregularities of various rock units. Field verification of the integrated mineral potential maps confirmed the presence of copper sulphide in the vicinity of St. Catherine. It was concluded that the maps could be used to define suitable locations for sulphide mineralization exploration.
