Figure 2

Illustrates (a) RGB color composite image of B8/B4, B4/B2, and B11/B12 ratios, (b) Kaolinite mineral index based on (B4/B8)*(3 + 4)/11 band ratio (red pixels refer to Matulla Formation and yellow pixels refer to the other clayey geological units), and (c) RGB color composite image of PC1, PC2 and PC3 indicates the occurrences of Kaolinite mineral (clay minerals: yellow pixels). These figures were generated from Sentinel-2A MSI image (S2A_MSIL1C_20190220T081951_N0207_R121_T36RWT_20190220T102134, Copernicus Open Access Hub; https://scihub.copernicus.eu/dhus/#/home) by using Envi 5.4 processing and analysis tools (Trial Version, https://www.l3harrisgeospatial.com/Software-Technology/ENVI).
