The Tyrkanda gold-bearing region is located in the South-East part of Yakutia within the Aldan Precambrian granulite-gneiss region and the Tyrkanda area of Mesozoic magmatism and gold mineralization of Aldan-Stanovoy shield. Despite the long history of development of gold placer deposits in the area, primary sources for some of them have not yet been founded and are not characterized. The typochemical and morphological features of native gold from placers of Tyrkanda gold-bearing region, in particular r. Bolshaya ...

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...
