Geophysical Considerations on Lithospheric Composition in the Western Yakutia

60th EAGE Conference and Exhibition, 1998
New aspects of the Western Yakutian geological composition were obtained with advanced techniques of geophysical processing. These data allow to improve empirical methods of kimberlite forecast. The results of complex geophysical investigations in the Western Yakutia carried out by "Alrosa"Co. Ltd. in 1995-97 are presented.

Lithium-bearing brines in the Daldyno-Alakatsky district (Western Yakutia)

Geography and Natural Resources, 2008
Abstract Presented are the results from investigating the regularities of lithium distribution in salt waters and brines of the Daldyno-Alakatsky district (Western Yakutia). It is established that lithium concentration in the groundwater under investigation exceeds many times (by factors of 10 to 20) the concentration contents, according to which the

Application of High-frequency Seismic Method for Kimberlite Prospecting in Western Yakutia

Proceedings (EAGE), 2008
В сложных геологических условиях Якутской кимберлитовой провинции для поисков коренных месторождений алмазов трубочной формы применяются нетрадиционные методы работ – высокоразрешающие технологии сейсмических наблюдений МОГТ. Диатремы фиксируются контрастными волновыми аномалиями, изометричная форма которых в плане позволяет отличить их от прочих ...

Geology and mineral composition of Zarya kimberlite pipe, western Yakutia

Domestic geology, 2021
The geological and tectonic settings of new primary low-grade diamond deposit, the Zarya pipe (Alakit-Markhinsky kimberlite field, Yakutian diamond province, Western Yakutia, Russia), are discussed. Data on the geological structure of the diatreme, mineral composition and kimberlite diamond content is presented. The factors determining the vertical and

Deep structure of Western Yakutia from magnetotelluric soundings

Izvestiya, Physics of the Solid Earth, 2006
Analysis of magnetotelluric (MT) sounding studies in western Yakutia showed that amplitude curves are strongly affected by the regional distribution of electrical conductivity heterogeneities of the sedimentary cover, while phase curves are distorted to a lesser extent.

The role of plicative structures as forecast criteria in the Alakit-Мarkhinsky field (western Yakutia)

Ores and metals, 2021
This paper describes the tectonic features of the Alakit-Markha kimberlite field, regional factors of kimberlite magmatism control in this area, structural and tectonic preconditions for kimberlite pipe prospecting. The paper highlights kimberlite pipe formation features and the role of tectonics in this process.
