MNR

Ministry of Natural Resources
and Ecology
of the Russian Federation


Rosnedra

Federal Agency
of Mineral Resources



The CIR solves actual problems of geology:

1) Creation of new generation geological maps;
2) Regional and exploration studies;
3) Study of formation conditions and mineral deposit localization peculiarities;
4) Creation of isotope and geochemical register of Russia’s mineral deposits:
isotope and geochemical passportization of high-liquid raw materials.

CIR can provide isotope study of the following directions of the MNR activity:

Biological resources:
Estimation of biosystem stability to the antropogenous factors: isotope tracing matter migration in biological communities.

Ecology:
Pollution source identification: isotope tracing waste-related chemical element migrations.
Current ecological monitoring: measurement of peculiarities of waste component accumulations, including short-life nuclides in natural environment.

Aquatic economy:
Natural water quality control: isotope and geochemical water scoop monitoring.
Creation of water resource register: isotope and geochemical passportization.
Study of water balance and matter migration in the most important water systems: isotope and geochemical tracing of water migration.

Soil Science and forest economy:
Determination of tree ages and estimation of speed of forest resource growth.
Source identification of the forest raw: isotope passportization of timber from different regions.


Isotope methods realized in CIR:

I. Isotope geochronology

Rb-Sr age dating (bulk rock and individual minerals).
Sm-Nd isochrone age dating (bulk rock and individual minerals).
U-Pb age dating (zircons)
K-Ar age dating (micas, amphiboles).
Radiocarbon (14C) organics age dating.
T-He underground water dating
Point methods:
U-Pb age dating of zircon grains.

II. Methods of isotope geochemistry:

Determination of the initial Sr and Nd isotope composition (bulk rock)
Determination of C, O and Sr isotope composition in carbonates
Determination of the initial S and Pb isotope composition in sulfides
Determination of C and N isotope composition in hard organic samples (coal, bituminous and graphite shales, graphite)
Determination of C and N isotope composition gas and oil
Determination of H and O isotope composition in water
Determination of short-life radionuclides in natural environment
Determination of noble gas isotope compositions (He, Ne, Ar, Cr, Xe) in silicate minerals
Determination of noble gas isotope compositions (He, Ne, Ar, Cr, Xe) in hard organic samples


Point methods of isotope geochemistry:

Determination of Rare Earth Elements (REE) distribution in mineral zones
Determination of trace elements distribution in mineral zones (including REE and PGE for sulfides and native noble metals)
Determination of the initial Hf isotope composition in the zones of zircons
Determination of the Pb isotope composition in the zones of feldspars
Determination of the Sr isotope composition in the zones of carbonates
Electron microprobe study of minerals
