“…A special case of SIs is represented by band ratios, where the ratio of two spectral bands is computed. Several SIs have been proposed using a range of wavelength combinations for mapping various mineral assemblages (Cloutis, 1996;Sabins, 1999;Cudahy and Hewson, 2002;Yamaguchi and Naito, 2003;Henrich et al, 2009;Shim et al, 2021), especially after the arrival of ASTER data with their SWIR spectral bands (Abrams et al, 1983;Abrams & Hook, 1995;Yamaguchi et al, 1998;Yamagushi & Naito, 2003;Kalinowski and Oliver, 2004;Gad and Kusky, 2007;Rajendran et al, 2011;Abrams et al, 2015;Ferrier et al 2016;Askari et al, 2018;Shuai et al, 2022) and/or Landsat 8 data (Anifadi et al, 2016;Ferrier et al 2016;Tompolidi et al, 2020;Anifadi et al, 2022;Sykioti et al 2022), spectral unmixing on (i) S-2, ASTER and Landsat 8 OLI data (Tompolidi et al, 2020) and (ii) EO-1 Hyperion hyperspectral data (Nikolakopoulos et al, 2007), Spectral Angle Mapping and Mixture-Tuned Matched…”

“…During the last three decades, the use of satellite imagery in geological mapping and mineral exploration has grown rapidly in order to detect mineralization-related alterations and associated ore deposits (Van der Meer et al, 2012;Van der Meer and Van der Werff, 2014;Van der Meer, 2015, 2016;Ge et al, 2018(a), 2018(b); Hu et al, 2018;Van der Meer et al, 2018;Pour et al, 2019;Vasuki et al, 2019;Ferrier et al 2019;Tompolidi et al, 2020;Anifadi et al, 2022). Recent multispectral satellites such as the Landsat Operational Land Imager (OLI), and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) have been the most widely used multispectral satellite sensors for the detection and mapping of minerals related to alteration, such as iron oxides, hydroxyl-bearing minerals, and Volume 59 carbonates (Rowan and Mars, 2003;Rowan et al, 2006;Ferrier et al, 2010Ferrier et al, , 2016Mars and Rowan, 2010;Hosseinjani et al, 2011;Pour et al, 2011;Rajendran et al, 2017;Yang et al, 2018;El Kati et al 2018;Abubakar et al, 2019;Pour et al 2019;Ferrier et al 2019;Tompolidi et al 2020;Vural et al, 2021), especially, when the satellites provide spectral information in the shortwave infrared (SWIR) part of the electromagnetic spectrum.…”

“…In particular, concerning Fe-Ni-laterite and/or bauxite detection and characterization, several processing techniques have been proposed using Earth Observation (EO) data, such as band ratios (BRs), Principal Component Analysis (PCA) applied to ASTER and Sentinel-2 data [31][32][33], sub-pixel-based classification techniques on hyperspectral data such as Linear Spectral Unmixing (LSU) [32,34], and various regression methods on Sentinel-2 data [21,35,36]. Other studies have focused on the use of reflectance spectroscopy techniques and Spectral Indices in order to recognize general categories of Fe-Ni-laterite or bauxite-related mineral assemblages, such as iron-bearing minerals and/or iron oxides [19,21,22].…”
