Determination of relationship between basement faults and alteration zones in Bafq-Esfordi region, central Iran

Abstract

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.

The Relationship between Fe Mineralization and Magnetic Basement Faults using Multifractal Modeling in the Esfordi and Behabad Areas (BMD), Central Iran

“…The structural zone includes the Anarak-Bafq-Kerman metallogenic belt (Berberian and King, 1981). The general trend of structures in the Bafq area is NW-SE (Nabilou et al, 2018). The Bafq region has become one of the most important mineralized zones of central Iran with the Upper Precambrian metamorphic-sedimentary rocks and Rift series of Precambrian-Paleozoic (Haghipour, 1977;Samani, 1988).…”

“…In Table 1, the general physical properties ('susceptibilities') of the rock types in the study area are summarized based on Soheili and Mahdavi (1991) and Mahdavi (1996). The Relationship between surface structures (e.g., Khavari et al, 2009;Arian et al, 2012;Arian and Aran, 2014;Ehsani and Arian, 2015;Aram and Arian, 2016) and basement faulting (e.g., Nabilou et al, 2018;Mansouri et al, 2018) show that Iran is affected by active tectonics. In terms of lithofacies, especially the role of tectonics in the Iran sedimentary basin, Arian (2015), Razaghian et al (2018) and Taesiri et al (2020) divided all rocks into several large tectonic-stratigraphic units.…”

“…1 and 2) (Mo'tamedi and Tahmasebi, 2009). The Relationship between sedimentary basins (e.g., Khavari et al, 2009;, 2012; Arian and Aram, 2014;Ehsani and Arian, 2015;Aram and Arian, 2016) and basement faulting (e.g., Arian, 2012;Nouri et al, 2013a,b;Mansouri et al, 2017;Nouri and Arian, 2017;Mansouri et al, 2018;Nabilou et al, 2018) indicates the role of faults in the control of sedimentary basins in Iran. In terms of lithofacies, especially the role of tectonics in the Iran sedimentary basin, Arian (2015), Razaghian et al (2018) and Taesiri et al (2020) divided all rocks into several large tectonic-stratigraphic units.…”

Relationship between Fe-Cu-REEs mineralization and magnetic basement faults using multifractal modeling in Tarom region, NW Iran

“…Relationship between structures and mineralization is a fundamental study for regionalized exploration for magmatic and hydrothermal ore deposits (Pirajno, 2009;Mustansar et al, 2016). The ideas about the relationship between mineralization and geological structures were introduced in 1950s (Adib et al, 2017;Nabilou et al, 2018). Airborne geophysical data are useful instruments to determine structures especially basement faults (Safari et al, 2016;Ahmadfaraj et al, 2019).…”

“…Airborne geophysical data are useful instruments to determine structures especially basement faults (Safari et al, 2016;Ahmadfaraj et al, 2019). To explore the relationship between structures, several mathematical methods specifically fractal modeling are widely adopted (e.g., Agard et al, 2005;Safari et al, 2016;Adib et al, 2017;Nabilou et al, 2018;Ahmadfaraj et al, 2019). Distribution and dispersion of elements rely on geological features such as magmatic rocks, sedimentation, structures (e.g., faults), metamorphism and mineralization.…”
