New аge data for the Gerdiz Massif (Polar Urals)
https://doi.org/10.52349/0869-7892_2022_92_50-63
Abstract
The Gerdiz massif in the Polar Urals was identified as an autochthonous granite-pluton of the Ordovician age, formed by seepage of Precambrian schists by granitic material. Оn state maps of the new generation, the Gerdiz massif retains its morphological features, but with conflicting interpretations of its geology. New geological data testify to the artificial allocation of a massif that combines rocks of different origin and age. Intensely dislocated (cataclased) metasomatized rocks of the Khanmeikhoi Formation and an A-type alkaline granite massif were combined into the Gerdiz massif.
