Combination of domes and synform structures is a normal structural paragenesis of the Precambrian granulitic terranes. Structure of ore fields depends on deformations, related to granitic-domical tectonics. Deposits are usually confined to synforms framing domes. Such localization indicates motion and concentration of ore material in connection with tectonic transport on shoulders of emerged domes and transformations of rocks as a result of effect of rheomorphic granitoid mass [1]. Deposits of iron (with cobalt an...
