General information

Name of the project: Origins, metallogeny, climatic effect and the cyclical nature of large igneous provinces

Strategy for Scientific and Technological Development Priority Level:  б

Goals and objectives

Research directions: Origins, metallogeny, climatic effect and the cyclical nature of large igneous provinces

Project objective: Creation of a laboratory for geochronology and geodynamics equipped with high precision analytical equipment on the basis of which we will conduct breakthrough research in solving problems of formation of large igneous provinces and unique mineral deposits related to them, the cyclical nature of catastrophic magmatic events, change of the climate and the organic world in the Earth's history.


The practical value of the study

  • We have described geochronological correlation between ore-producing ultrabasite-basite complexes of suture zones, alkaline and granitoid associations of the Central Asian fold belt and estimated their mineralogical potential.
  • Preliminary models of polychronic alkaline basite magmatism in Northern and Central Asia.
  • Our researchers have described the principles of the correlation between geological events and transformation of the climate and the organic world.
  • We have determined a concept of comparison of different isotope geochemical systems for diagnostics of age and sources of substance in rock mineral association.
  • Our researchers have evaluated potential impact of formation of large igneous provinces on changes in the organic world of the Earth.
  • Preliminary criteria of mineralization have been developed as well as recommendations for Russian and foreign companies in the field of subsurface resources management.

Education and career development:

  • One candidate dissertation has been defended.
  • We have introduced the following general training programs to the curriculum of the Tomsk State University (lecturer – Richard Everett Ernst): «Introduction to large igneous provinces», «Global geological and climate change and their relation to large igneous provinces», «Large igneous provinces – petrological implications», «Large igneous provinces of terrestrial planets».

Organizational and structural changes:

  • A new laboratory of geochronology and geodynamics has been created to investigate geological object of the Siberian region.
  • A unique analytical laboratory which has no analogues in Russia in terms of competences (inductively coupled plasma mass spectrometry, equipped with an Agilent 7900 double quadrupole, a Teledyne CETAC Analyte Excite 193 nm excimer laser ablation system with HelEx cell).

Collaborations:

  • University of Washington (USA): joint research (sponsored by a Russian Science Foundation grant for 2018–2020)
  • University of Salamanca (Spain): joint research (results of research in alkaline magnetism and HP-metamorphism have been compiled and published)
  • China University of Geosciences (China PR): joint research and publications
  • University of California (USA): joint scientific events, internships of members of the academic staff of the laboratory in setting analytical methodologies
  • V.S. Sobolev Institute of Geology and Mineralogy of the Siberian Department of the Russian Academy of Sciences: joint research, internships of academic staff members, preparing collaborative publications, conducting the 4th International conference «Correlation between the Altaides and Uralides: deep structure of the lithosphere, stratigraphy, magnetism, metamorphism, geodynamics and metallogeny» (Novosibirsk, 2018)
