ELEMENTS - IMPURITIES AND INTERNAL STRUCTURE OF NATIVE GOLD OF THE GEDABEK DEPOSIT AND THEIR PRACTICAL IMPORTANCE

Abstract

Impurity elements and the internal structure of native gold, which provide valuable information in determining the stages and stages of ore deposition, are considered. The results of analytical studies established that the composition of native gold contains the following impurity elements (%): Cu (0.008-0.012), Fe (0.0015-0.006), Sb (0.03-0.04), As (0.001-0.002), Bi (0.002-0.005), Zn (0.008-0.001), Pb (0.006-0.005), Mo (0.0002), Hg (0.1-1.27). As you can see from the analysis results, there are increased concentrations of Sb, As and Hg in native gold. Which gives reason to assume that the Gedabek deep fault also played a certain role in the formation of this field. A homogeneous, unclearly zoned, colloform internal structure of native gold has been revealed, which makes it possible to determine the deep formations of ores, as well as to clarify the stages and stages of ore deposition of this deposit.
