As a result, low- and moderate-pressure series of regional metamorphism turn out to be juxtaposed. Moderate-pressure metamorphism related to collision [1] is locally superimposed on low-pressure metamorphic rocks. Therefore, andalusite is progressively replaced with kyanite, and new mineral assemblages of moderate pressure and deformational microstructures are formed. The replacement of andalusite by kyanite in the Yenisei Ridge is not a common phenomenon, because the stationary continental geotherm, as a rule, does not intersect the andalusite–kyanite equilibrium line.
