The distribution of elements in soil is affected by various natural processes, and therefore, it is essential that exploration geochemists are able to recognize whether an elemental concentration is related to mineralization or other processes. This research aimed to recognize the elemental distribution and its controlling factors around the Zhaoji...
Article
Traditionally, a geochemical exploration index is based mainly on elemental concentration, and focusses on positive anomalies. This results in two problems: firstly, it ignores depleted elements, negative anomalies, and immobile elements, and secondly, elemental concentration does not directly reveal the degree of elemental mobility. To discover in...

... The PLS-DA is a supervised classification technique using labeled data compared to the traditional analysis, which achieves maximum separation between categories by rotating the PCA components to reinforce the separation between observation groups, which in turn identifies different categories of separated variables [2,[5][6][7][8][9][10]. Currently, the discriminatory models are constructed by such methods to study the chemical composition of minerals such as magnetite [4,11], scheelite [12], tourmaline [13], and chalcopyrite [8], and to discriminate deposits and ore types such as the uranium deposits [14], gold deposits [15], magmatic Ni-Cu sulfide deposits [16,17], sphalerite [18], and lead-zinc deposits [19], as well as the ore-prospecting prediction [20,21]. ...
... To establish another approach to geochemical mapping, Zuo et al. [26] applied deep learning and indicated that this method could deal with nonlinear and complex problems. In addition, various ML techniques have been used to detect the content as well as the potential of minerals and geochemical anomalies as the following works [18,25,[27][28][29][30][31][32][33][34]. ...
