Petrographic-geochemical characterization of rocks and evaluation of prospectivity of Yakokut massif (Central Aldan)
- Authors:
- I. N. Kritsuk
- E. E. Plyushchev
The genetic relationship between magmatism and endogenous mineralization has always been one of the most important problems of geology and geochemistry. The connection of gold mineralization of the Central Aldan with Mesozoic alkaline magmatism has been discussed many times in the works of Y.A.Bilibin, T.V.Bilibina, E.P.Maksimov, G.K.Shnay, M.P.Orlova and others.

Geochemical prospecting features of gold mineralization in dikes of the Inyali-Debinsky synclinorium
- Authors:
- V. P. Polevanov
- S. V. Sendek
The territory of the south-eastern part of the Inyali-Debinsky synclinorium is known as the main mesozoid gold-ore zone of the North-East of the USSR. Systematic geologic studies have been conducted here for more than half a century.

Gradation of gamma-spectrometer logs with the help of small ore models
- Authors:
- V. V. Vyshenkov
- G. F. Novikov
The grading of field logging f-spectrometers is an important but poorly developed issue. Usually it is performed in f-saturated media modeling the conditions of measurements in boreholes.

Some questions of methodology of the active raid method
- Authors:
- A. L. Poleshchuk
- A. M. Gilevich
In prospecting for uranium deposits, much attention is paid to various modifications of the emanation method. The most promising type of survey is the method of active raids.

Four-channel amplitude spectrometer
- Authors:
- A. Ya. Sinitsyn
- R. M. Gabitov
Serially produced radiometric and nuclear geophysical spectrometers with rare exceptions contain one or two measuring differential channels, which complicates research and does not provide high labor productivity. As experience of geophysical works shows, radiometric spectrometer should have at least three independent differential channels, nuclear geophysical spectrometer - three-four, and sometimes more channels.

Theory of effective nuclear geophysical parameters of heterogeneous ores
- Authors:
- V. A. Artsybashev
The construction of modern theory of gamma- and neutron methods of nuclear geophysics should be based on the description of photon and neutron fields in heterogeneous media, reflecting the real structural features of ores.

X-ray radiometric sampling of silver ores in mine workings
The deposit, where the X-ray radiometric sampling (XRD) of the walls of mine workings was carried out, is confined to the local uplift of the graben-shaped sag, composed of Cretaceous volcanogenic and sedimentary-volcanogenic formations.

X-ray spectral dispersionless analysis of ceramic raw material samples
- Authors:
- Yu. O. Kozynda
- O. I. Yavorsky
The increasing demand of the industry for ceramic raw materials leads to a sharp increase in their extraction. The increase in extraction implies an improvement in the quality of the raw materials supplied to the processing companies, which makes it possible to increase the economic efficiency of the industry.

Nuclear-geophysical logging of explosive open-pit wells at copper-coal deposit
- Authors:
- A. A. Volkov
Ore sampling in the massif is an important link in the chain of mining and geological problems solved during the exploitation of deposits. Information on the spatial location of ore and its quality is used in the organization of mining operations, including measures to reduce ore losses and dilution and in planning the operation of mines in the averaging mode.
