Lay Summary (English)

Lead
The Lesser Caucasus is a major ore deposit regions of the Tethyan metallogenic belt. The potential for remaining resources is important and explains the interest of international mineral exploration and mining companies. Major ore deposit types include porphyry-Cu±Mo±Cu, volcanogenic massive sulfide and epithermal deposits. The global geodynamic setting is better understood, there is still a poor understanding about the details of magma petrogenesis and ore deposit formation.
Lay summary
The Lesser Caucasus is a major ore deposit region of the Tethyan metallogenic belt, where Cu, Au and other metals are produced. Major ore deposit types include porphyry-Cu±Mo±Au, volcanogenic massive sulfide and epithermal deposits. While the global geodynamic setting starts to be better understood and constrained, there is still a poor understanding about the details of magma petrogenesis and ore deposit formation in the Lesser Caucasus. The controversies reflect a lack of adequate descriptions of host environments, little absolute dating with modern techniques, and a poor understanding of stratigraphic and structural relationships. Our aim is to study several ore deposit districts, and integrate ore formation processes into regional magmatic, tectonic and geodynamic events.This project includes teams from Georgia, Armenia, Azerbaijan and Switzerland. The researchl includes (1) basic research of selected ore deposits and their immediate geological environment, (2) district related research to understand the spatial and temporal relationships among different ore deposits and prospects, as well as magmatism, and their link with the geological evolution of the different mining district, and (3) at the scale of the orogenic belt, including along belt and transverse belt research to integrate ore formation processes into regional events. The project will be focused on three cross-sections across the Southern Caucasus. This will allow us to characterise the spatial and temporal association of given ore deposits, and therefore metal enrichments in the crust, with specific magmatic and tectonic events. Each cross-section will include some of the major ore districts or ore deposit clusters of the Lesser Caucasus.The methods of investigations include field work, lithogeochemistry, stable and radiogenic isotope geochemistry, microscopy, fluid inclusion microthermometry, and absolute dating (mainly U-Pb, Ar/Ar and fission-track). This project will improve our knowledge about the metallogeny, magmatic and geodynamic evolution along the Tethys belt spanning Jurassic to Cenozoic times. It will allow us to constrain age relationships among ore forming events and regional tectono-magmatic events in the Lesser Caucasus. This project will improve our general understanding of the formation of different types of ore deposits, including porphyry-Cu deposits, volcanogenic massive sulfide deposits and epithermal deposits along the Tethys. It will offer us the possibility to construct more robust geodynamic and metallogenic models at the scale of the entire Tethys belt.

Abstract

The Lesser Caucasus is one of the major ore deposit regions of the Tethyan metallogenic belt, where Cu, Au and other metals are produced. The potential for remaining resources is important and explains the interest of international mineral exploration and mining companies for this part of the world. Major ore deposit types include porphyry-Cu±Mo±Cu, volcanogenic massive sulfide and epithermal deposits. While the global geodynamic setting starts to be better understood and constrained, there is still a poor understanding about the details of magma petrogenesis and ore deposit formation in the Lesser Caucasus.The controversies reflect a lack of adequate descriptions of host environments, little absolute dating with modern techniques, and a poor understanding of stratigraphic and structural relationships. Volcanogenic massive sulfide and pophyry-Cu associations are reported, but are paradoxical since they are considered as incompatible ore types from a geodynamic point of view. Moreover, the exact nature of epithermal deposits is open to many questions, as their characteristics are not known accurately to understand their affinity with respect to the large classes of epithermal deposits. Our aim is to study several ore deposit districts, and intergrate ore formation processes into regional magmatic, tectonic and geodynamic events.This SCOPES project will include four teams from Georgia, Armenia, Azerbaijan and Switzerland. The research will be carried out at three different levels; (1) basic research of selected ore deposits and their immediate geological environment, (2) district related research to understand the spatial and temporal relationships among different ore deposits and prospects, as well as magmatism, and their link with the geological evolution of the different mining district, and (3) at the scale of the orogenic belt, including along belt and transverse belt research to integrate ore formation processes into regional events. The project will focus on three distinct cross-sections placed roughly transversally across the Southern Caucasus. This will allow us to characterise the spatial and temporal association of given ore deposits, and therefore metal enrichments in the crust, with specific magmatic and tectonic events. Each cross-section will include some of the major ore districts or ore deposit clusters of the Lesser Caucasus.The methods of investigations to collect the data of the project will include field work, lithogeochemistry, stable and radiogenic isotope geochemistry, microscopy, fluid inclusion microthermometry, and absolute dating (mainly U-Pb, Ar/Ar and fission-track). This project will improve our knowledge about the metallogeny, magmatic and geodynamic evolution along the Tethys belt spanning Jurassic to Cenozoic times. It will allow us to constrain age relationships among ore forming events and regional tectono-magmatic events in the Lesser Caucasus. This project will improve our general understanding of the formation of different types of ore deposits, including porphyry-Cu deposits, volcanogenic massive sulfide deposits and epithermal deposits along the Tethys. It will offer us the possibility to construct more robust geodynamic and metallogenic models at the scale of the entire Tethys belt.The Georgian team will mostly work on the Bolnisi district, the Azerbaijani team mostly on the Karadag district, the Armenian team mostly on the gold districts, the Alaverdi-Teghut ore deposit cluster and the Kapan-Megrhi region. The field aspects will be clearly under the responsibility of the different Caucasian groups. Regional and magmatic aspects will be shared by the different groups, and laboratory studies, including radiometric dating and litho- and isotope geochemistry will be under the responsibility of the Swiss group. Some of the field work activities will be conducted jointly by the Swiss team and the Caucasian teams. Visits of selected scientists of the Georgian, Armenian and Azerbaijani groups to Geneva will be organized to allow them to carry out or help with selected laboratory studies (e.g. microscopy, geochemistry, microprobe), and to discuss and interpret results with the aim to prepare manuscripts for publication in international, peer-reviewed scientific journals.The planned research is significant for our partner countries for different reasons. It is relevant for education, and for training partners in the Caucasian states, and it will have impacts on the economy and the employment of Georgia, Armenia and Azerbaijan on a long term basis.This SCOPES proposal requests financial support that is fundamental for our partners from Georgia, Armenia and Azerbaijan for carrying out field and laboratory investigations that meet international standards of quality, and which cannot be supported by Georgian, Armenian or Azerbaijan sources of funding.The ultimate goal of our collaboration is that the SCOPES partners from Georgia, Armenia and Azerbaijan will undertake independent, effective and problem-oriented research. This joint proposal will also permit us to improve the collaboration between the university environment (typically primarily devoted to education) and the environment of research (Academy of Sciences). It will also improve the international recognition of research by Georgian, Armenian or Azerbaijani scientists and give them a broader audience to disseminate their results. The ultimate goal is to submit different manuscripts to international scientific journals with peer reviews for publication.
