Advanced nuclear radiation shielding studies of some mafic and ultramafic complexes with lithological mapping

Landsat-8 OLI/SRTM and gravity characteristics of the Pan-African fracture aquifers of the north central Cameroon region (central Africa)

“…According to Refs. [ [11] , [12] , [13] , 57 ], CB is a mathematical operation applied to bands. According to Ref.…”

“…These cracks would be fault zones or shear zones, in accordance with [ 59 ]. To decrease highly linked multidimensional data for accurate geological interpretations, PCA is a method of linear transformation [ 11 , 29 , 59 , 60 ]. For lineament extraction, it provides the optimal combination of independent bands from Landsat-8 OLI images.…”

“…4 a-d). The PCA technique has been utilized internationally [ [11] , [12] , [13] , [60] , [61] , [62] , [63] , [64] ] and in Cameroon [ [29] , [30] , [31] , 65 ]. Next, the color composition (CC) technique assigns red (R), green (G), and blue (B) to the initial image to optimize visual analysis.…”

“…[ 9 , 10 ], the major water flow comes from deep fractures. Recently, remote sensing studies provided new insights on mineral resource mapping [ [11] , [12] , [13] , [14] , [15] , [16] , [17] ] and on spatial mapping of this reservoir [ [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] ]. Remote sensing is advantageous where plant cover and soil cover are important.…”

Satellite data based abundance mapping of mafic and ultramafic rocks in Mettupalayam, Tamil Nadu, India

“…Different band combinations can be generated and they can be well suited for the identification of rocks, minerals, vegetation, etc. (Gomez et al 2005, Libeesh et al 2021. Based on the spectral behavior, various band combinations were derived for mafic and ultramafic rocks.…”
