In the territory of the At-Uryakh-Shturmov zone there were three richest placers of Kolyma, now almost completely mined out. Native ore occurrences identified in the area of the zone are not comparable to the placers. Nevertheless, the regularities in the distribution of ore occurrences, established as a result of the conducted research, show that their number is far from being exhausted by the known ore occurrences, and, consequently, significant metal resources may be concentrated in them. However, in order to turn these resources into real reserves, it is necessary to take into account the laws outlined in the proposed article when prospecting and exploring these ore occurrences.

The structures of native gold deposits in the Northeast of the USSR have repeatedly attracted the attention of geologists.

Geochemical criteria are established on the example of one of the fields in Yakutia. Climatic conditions predetermined the widespread development in the area of permafrost up to a depth of 300 m.

The deposit is confined to the southern periclinal closure of the anticline, composed of a monotonous thickness of calcareous-clay siltstones and shales. The rocks are characterized by abundance of pyrite and marcasite nodules. The rocks are not characterized faunistically, but lithologically they parallel the Kukkan Formation of the Lower Permian of the unified stratigraphic scheme of the Southern Verkhoyany. The mineralization is localized in crushing and buckling zones of near meridional strike and in quartz veins of near-latitudinal strike. Both have a steep dip at an angle of 70-80°; the zones are westward, and the veins are northward ...

The Nezhdaninskoye gold deposit is located in the northern part of the South Verkhoyansk synclinorium and is situated in the vaulted part of the southern periclinal closure of the box-shaped Dybinskaya anticline. The intervening rocks are represented by a monotonous thickness of sandy siltstones and shales of Lower Permian age.

All the most interesting in practical terms deposits and ore occurrences within the South Slope of the Gissar Range are hydrothermal in nature and localized within the zones of rupture faults. In this connection, geochemical sampling of the material composing the zones of tectonic faults becomes extremely important, because it is obvious that the basic patterns of element introduction or removal in the faults can be used as geochemical criteria for age dissection of faults or assessment of prospects for their metalliferousness.

As a rule, works considering the geochemical specialization of rocks concern intrusive formations and mainly granitoids, since they dominate the lithosphere and are naturally the most thoroughly and comprehensively studied. It seems interesting to analyze the geochemical specialization of the main effusives (basalts) of some areas of the Pacific ore belt, mainly from the point of view of its relation to the tin content of the region.

The compilation of geochemical maps should be preceded by a clear formulation of the concept of geochemical map. As it is known, there are different points of view and different understandings of map construction and practically there is no experience in making polyelemental geochemical maps.Under geochemical the authors understand a map that reflects the content, character of distribution and form of finding a wide range of chemical elements in the bedrock. Such a map should be one of the main in the creation of metallogenic and prognostic-geological maps ...
