SIGNS OF SULFIDE MINERALIZATION OF BASALTS OF THE GREAT KUREYSKY WATERFALL (PUTORANA PLATEAU)
The geological structure of the Tunguska series of the Siberian platform is shown in connection with the development of a modern river network on the Putorana plateau among of tholeiitic basalts. In the hydrographic network, deep canyons are established, in shape in plan and section reminiscent of a «tortoise shell». Signs of sulfide mineralization of basalts are established within the Great Kureysky waterfall. At the bottom of the naked channel, the decomposition products of sulfides in the form of crystalline sulfate iron hydrates were determined. Reservoirs with hydroxide iron were installed within the limits of erosion (eurasion) boilers. The presence of sulfide decomposition products can be used as a direct search sign of sulfide mineralization.
