Data for: Delineation of deep prospecting targets by combining factor analysis and fractal methods in the Kekeshala skarn Cu deposit (China)
The borehole samples were crushed, reduced in volume, and pulverized to 200 mesh. Geochemical analyses of samples were performed using different methods at the Seventh Geological Group Analytical Laboratories of Xinjiang Geology and Mining Bureau in China. Au was dissolved in aqua regia and fluoride and then enriched using activated carbon, while Ag was dissolved in aqua regia. Both concentrations were determined through flame atomic absorption spectrometry. Ba was melted using NaCO3, while Cu, Mo, Pb, W, Sn, and Zn were dissolved by the mixture of hydrochloric acid, nitric acid, hydrofluoric acid, and perchloric acid. The results were determined by ICP–OES and full-spectrum direct-reading plasma-emission spectrometry. As, Sb, and Bi were dissolved in aqua regia, and their concentration was determined through atomic fluorescence spectrometry. A total of 4,878 samples were collected from different depths of the borehole in the district.
