Department of physical-chemical methods of analysis
Brief historical background: The laboratory (now the department) of physical-chemical
methods of analysis was established in 2006 under the leadership of candidate of geological and
mineralogical sciences V.S. Suknev by merging laboratories: spectral analysis methods, X-ray
analysis methods, mass spectral analysis methods and chemical analytical laboratory. Since
2011, the department has been headed by L.T. Galenchikova.
The Analytical Department, one of the first structural divisions of the Institute of
Geology, YB SB of the USSR Academy of Sciences, was established in 1957. the first head of
which was V.D. Shalitskaya.
The chemical analytical laboratory was headed by candidate of chemical sciences K.S.
Pakhomova (1958-1960), K.I. Kashirtseva (1961-1975), candidate of chemical sciences A.I.
Kalinin (1975-1980), V.V. Gamyanina (1980-2004), L.T. Galenchikova (2004-2006).
Since 1957, works in the field of absolute geochronology began in Yakutia under the
leadership of N.I. Nenashev, who headed the laboratory for determining the absolute age of
geological formations for 30 years and handed it over in 1987 to candidate of geological and
mineralogical sciences A.I. Zaitsev as a laboratory of mass spectral analysis methods.
In 1959 candidate of geological and mineralogical sciences I.Y. Nekrasov, subsequently,
the corresponding member of the Russian Academy of Sciences, organized laboratory of
physical-chemical research methods as part of the cabinets of spectral, X-ray diffraction, electron
microscopy and thermal analysis. In the 80s, the laboratory was divided into the laboratory of
spectral analysis methods (head, candidate of geological and mineralogical sciences V.S.
Suknev) and the laboratory of X-ray analysis methods (head N.V. Leskova).
RESEARCH DIRECTIONS:
Group of X-ray methods of analysis:
Thermal analysis: (Yemelyanova Н.Н.)
– Study of the properties of a substance and the processes occurring in it when heated
according to a given program.
– Research of thermal processes for the determination of a substance, to study reactions
in rocks and minerals (derivatograph STA 449 С Jupiter)
X-ray diffraction analysis: (Vasilyeva T.I.)
– Study of any crystalline materials (rocks, cements, soils, etc.):
– determination of the phase (mineral) composition
– determination of crystallographic characteristics for rare and new minerals
(diffractometer D2 PHASER, database PDF-2)
X-ray spectral analysis: (Khristoforova N.V., Popov A.V., Romanova D.Y.)
– Quantitative determination of the elemental composition of solid materials
– Determination of the composition of microinclusions (microanalyzer KAMEBAKS-
micro).
– Scanning electron microscope JSM 6480 LV JEOL in scan mode (magnification up to
150,000 times) allows exploring the topography of the surface, and in the microanalysis mode,
characterizing the heterogeneity of the material with simultaneous determination of the elemental
composition from carbon to uranium.
– The scanning electron microscope is equipped with a cathodoluminescent adapter,
which allows recording the glow of minerals such as diamond, quartz, spinel, calcite, apatite,
diopside, zircon and others that occur under the action of an electron beam. It can be used to
study inclusions, distribution of crystal lattice defects, the processes of growth and dissolution in
natural diamond crystals.

The main task of the department is to provide the research work of the Institute with
various types of analysis of rocks and minerals.
On June 29, 2017, the Center for the collective use of physical-chemical methods of
analysis was established (CCU PCMA), in accordance with the order on DPMGI SB RAS based
on the decision of the scientific board of the Institute.
CCU PCMA was established on the basis of the department of physical-chemical
methods of analysis, DPMGI SB RAS and includes:
– methods of chemical-analytical analysis;
– spectral analysis methods;
– methods of X-ray and thermal analysis.
Over the years, the team has carried out not only analytical work in accordance with the
main activities of the Institute, the staff was engaged in methodological and scientific work,
engineers ensured a time-appropriate level of progress in the automation of devices. A lot of
methodological work has been done to determine small inclusions by electron probe
microanalysis. With the active participation of the staff of the team, such minerals as native
aluminum, silicon, cadmium, lenaite, yafsoanite, indigirite, arangasite, mangazeite,
nabalamprophyllite and others were discovered with geologists. The laboratory staff were not
just analysts, but geochemists, mineralogists, crystallographers, experimenters
