“…The set of copper carbonates and iron oxides described in the mineral occurrence under study is frequently present in peripheral portions of proven sulfide deposits with subsequent surveys in the study region (CPRM, 1995;Silva et al, 2014), and serve as prospective guides in studies of mineral exploration for hydrothermal deposits in several world cases (Allis, 1990;Irvine & Smith, 1990;Moon et al, 2006;Salem et al, 2013;Darabi-Golestan et al, 2013;Dentith & Mudge, 2014).…”

The geophysical diagnosis of mineral deposits can be extremely useful in detailing mineralized zones and is a strategy for direct sampling by probing holes for content analysis. This study involves the combined use of Electrical geophysical methods (DC resistivity and Induced Polarization), geological recognition and structural field analysis, with a study of the mineralized occurrence of copper, previously described in a systematic geochemical survey carried out by the Geological Survey of Brazil (CPRM), located in the north of the Camaquã Basin, extreme south of Brazil. The mineral occurrence is partially outcropped and consists of quartz vein shafts with malachite and relic structures of sulfides, contained in schist. Structural data obtained in the field revealed the existence of a system of fracture pairs in the directions N40-50W and N70-80E. Such information is presented in the programming of the geophysical data acquisition scheme, which consisted of 6 lines of electrical tomography with 410m each, in azimuthal disposition and Schlumberger arrangement, where all lines cross a single center and are separated according to an angle of 30°, in an attempt to cover fractures in various orientations. The 2D results reveal the existence of high chargeability zones (>40mV/V) positioned below the 40m depth. These data were interpolated in 3D visualization models and generated resistivity and chargeability maps for several depths, which integrated with previous structural data, and indicate the existence of zones with potential sulfide concentration with strong structural control, in addition to clear target recognition for direct and objective probing evaluation, with rationalization of costs.

“…It is well known that porphyry copper mineralization is derived largely from the fractionation process associated with igneous rocks of calc-alkaline affinities [55,56]. These granites are regarded as good resources of magmatic fluids and heat for the formation of Cu-porphyry [57][58][59][60][61]. Copper plays a role of great importance in many industries related to high ductility, malleability, electronics, architecture, plumbing, building construction, thermal conductivity, and electrical and corrosion resistance.…”

Excess Lifetime Cancer Risk Associated with Granite Bearing Radioactive Minerals and Valuable Metals, Monqul Area, North Eastern Desert, Egypt

et al. 2022

The present work is concerned with assessing the cancer risk contributed by the studied granite types including valuable metals, such as Cu, Au, and Ba mineralization, as well as radioactive-bearing mineralization, such as monazite and zircon, in south Monqul at Wadi Makhrag El Ebel, north Eastern Desert, Egypt. The mineralization analyses illustrated that copper mineralization containing chrysocolla and tenorite minerals were restricted to the alteration zone, especially (argillic, phyllic, and propylitic) in monzogranite. However, barite veinlets had an ENE–WSW trend, while gold mineralization was confined to quartz veins having NE–SW trends. Monazite and zircon are radioactive-bearing minerals recorded in monzogranite causing high radioactive zones in south Monqul. The radionuclide activity concentrations were detected in the studied monzogranites. The mean values of AU (103 ± 91 Bq kg−1), ATh (78 ± 19 Bq kg−1), and AK (1484 ± 334 Bq kg−1) in the monzogranite samples were higher than the recommended worldwide average. The change in radioactive-transporting minerals found inside granite faults caused the high amounts of radioactivity seen in the samples. Due to the monzogranites being applied in building materials, the radiological hazards were assessed by calculating risk indices such as annual effective dose (AED) and excess lifetime cancer risk (ELCR). The acceptable limit for the ELCR readings was surpassed. As a result, the investigated monzogranite samples are not suitable for use in infrastructure materials.

“…The multi spectral image is widely used for mineral exploration, specifically to individuate the presence of altered minerals such as alunite, pyrophyllite, kaolinite, sericite, illite and muscovite (Salem et al, 2013). We used it in combination with airborne magnetic data for the determination of basement rocks and faults/structures deeper than 1 km.…”

The remote sensing was utilized for mineral exploration specifically to look for the presence of altered minerals. In addition, airborne magnetic data have been used for modelling of basement faults/structures. Furthermore, these data provide a synoptic view, which is helpful in the identification and delineation of various land forms, linear features and structural elements. Moreover, mapping geological lineaments is essential for regional exploration of hydrothermal deposits. The aim of this study is the determination of relationship between faults/structures and hydrothermal alteration zones based on geophysical and remote sensing data in the Esfordi area, central Iran. Basement faults were extracted by magnetic airborne data and alteration zones were detected using remote sensing data. Statistical and geostatistical parameters were determined in this area including correlation between areas of alteration zones and distances to faults, variograms and anisotropic ellipsoid. These reveal that there is a direct correlation between alteration zones and basement faults in the study area.
