The paper presents the results of comprehensive study of the primary diamond deposit of the Nyurbinskaya pipe in the Yakutian diamondiferous province. It is established, that the pipe is confined to the fault junction of four directions and is composed of the kimberlite of four phases. Analysis of different faults and tectonic fracturing allowed to reconstruct the tectonic stress fields acting at the stage of the kimberlite body formation and to determine their occurrence sequence in time. The data obtained about regularities of the Nyurbinskaya pipe compositional structure and results of geologo-structural studies are combined in a single structural-compositional model of the deposit formation. Peculiarities of the fault network operation during the deposit formation stage are confirmed by experimental results using polarization-optical method. The model allowed to formulate the basic structural characteristics of the prospecting works object within which the formation of kimberlite body type of the Nyurbinskaya pipe is possible and to determine the elements of the fault network which are promising for the kimberlite pipes discovery.

Gladkov et al.: Structural-compositional model of the Nyurbinskaya kimberlite pipe formation…кимберлитами четырех фаз. Анализ разноранговых разрывных нарушений и тектонической трещиноватости позволил восстановить поля тектонических напряжений, действовавшие на этапе формирования кимберлитового тела и определить последовательность их проявления во времени. Полученные данные о закономерностях вещественного строения трубки Нюрбинской и результаты геолого-структурных исследований объединены в рамках единой структурно-вещественной модели формирования месторождения. Особенности функционирования разрывной сети на этапе формирования месторождения подтверждены результатами экспериментов с использованием поляризационно-оптического метода. Полученная модель позволила сформулировать признаки, определяющие основные структурные характеристики объекта поисковых работ, в пределах которого возможно формирование кимберлитовых тел типа трубки Нюрбинской, и на их основании выделить те элементы разломной сети (разломные узлы), которые являются перспективными для обнаружения кимберлитовых трубок.

The problem of heat supply to remote dispersed consumers of the Arctic and the possibility of such a local renewable energy source as wind to be involved in are considered. The wind potency distribution over the western sector of the Russian Arctic is shown. Areas with enhanced wind potency are identified, which are the most promising ones for heating needs. Wind energy cadastre principal characteristics of the region are studied (average longterm wind speeds, seasonal distribution in average monthly speeds, wind speed frequency, etc.). There is a winter wind speed peak in coastal areas, which coincides with the cold season peak demand for heating power and electricity. This is the main prerequisite for the successful joint operation of current boiler rooms with wind power plants (WPP), which are able to provide a significant part of the heating load. It is shown that the use of wind energy will save (displace) a significant amount of expensive imported fuel and significantly reduce the working cost of heat generated. The climatic characteristics of the region are studied, and the values of reduced (taking into account the wind) outdoor temperature are estimated. The way how the wind strains the initial picture of the distribution of average annual air temperatures is shown. The consumer heating-load curve and its provision by WPPs possible participation and boiler rooms are considered. The share of high wind potency WPPs reaches 60-80% in one year.
