GOLD-BEARING CRUSTS OF WEATHERING OF THE UKRAINIAN SHIELD

Based on gold spectrometric analysis, the distribution of gold in the weathering crusts of the Ukrainian shield was studied. The mineralogical composition of the weathering crusts has been clarified - kaolinite, hydromica-clayey, zone of initial decomposition. Typical diagrams of the most common weathering crusts of the Ukrainian shield were constructed on rocks of different types: acidic and intermediate, basic, ultrabasic. The gold content in the weathering crusts of the Skvir area well was determined. It has been established that the kaolin weathering crust contains more gold - 0.5 g/t, brecciated rocks of the weathering crust have the same gold content (0.2 g/t) at different depths.
