Abstract
Dynamometamorphic lithologic transformations of ores and ore-hosting rocks are substantiated by the example of the Tishinka deposit and the upper beds of the Ridder-Sokol’noe deposit in Rudny Altai. The lenticular and lenticular-banded morphology of orebodies in the deposits is due to the in situ redeposition of ore substance in the form of bodies oriented concordantly with the direction of the maximum tangential stresses and, correspondingly, the general strike of the deformation-metamorphic structures. It is shown that dynamometamorphism is not only the structure- and rock-forming factor but also plays a great role in the concentration and localization of ores, favoring the formation of rich ore deposits in zones of intense deformations and structural and geochemical transformations. The age of the main phases of dynamometamorphic impact and the time of formation of the deposit orebodies are estimated. For the Tishinka deposit, it is 294-301 and 279-288 Ma (Early Permian), and for the lenticular orebodies of the upper beds of the Ridder-Sokol’noe deposit, ~307 Ma (Late Carboniferous).
