Abstract:
Relevance of the work. The conditions for the formation of chromium ores in alpine-type ultramafites remain a topical subject of research. In recent years, scientific papers have focused on the issue of changing the chemical composition of ore-forming minerals and chromium ores under the influence of deformation and dynamic recrystallization processes accompanying metamorphism. The results of such studies make it possible to formulate a new model of the formation of chromium mineralization taking into account a significant amount of geological data indicating that alpine-type ultramafic rocks

Abstract:
The overall objective was to create a geological and geophysical field test site for chromite mineralization and detailed works in order to determine and test the main search criteria for disseminated mineralization. To create a field test site, an area was selected in the southern part of the Klyuchevsky massif characterized by abundant development of disseminated mineralization in the banded dunite-clinopyroxenite complex and strong processes of superimposed metamorphism.

For the first time in podiform chromitites, a mineral of the humite group, titanium–containing hydroxylclinohumite, belonging to natural dense water-containing magnesian silicates (DHMS phases), was found. The find was made in chrome ores of the Paity plateau, located in the northern part of the Voikaro-Synyinsky ultramafic massif of the Polar Urals. Chromitites are deposited in the dunite body, which is located at the contact of apoharzburgite amphibole-olivine-antigorite and amphibole-enstatite-olivine metamorphic rocks containing relics of non-serpentinized harzburgites.
