Project summaryProject goal – to research the minerals of medium, high and ultra-high pressure in order to determine their physical-chemical conditions in the mid and lower parts of the earth’s crust as well as the upper mantle. It is also designed to determine their practical usage.
Minerals of medium, high and ultra-high pressure are usually formed in mid and lower parts of the crust and the upper mantle. By the character of their associations, directions of overlapped processes, changing features of their chemical content, zoning of their structure one could determine the course of physical-chemical processes on those depths, as well as analyze the geodynamic condition of the region around the time of their formation. Therefore these minerals are invaluable source of information about the nature of processes taking place in the deep parts of the crust and upper mantle, as well as about the possible reasons for the formation of magmatic masses, hydrothermal solutions and natural resource deposits. Structural-textual features of these minerals, associations will provide data on the character of deformation on those depths and the possible reasons for the occurence of centers of intra-crust and intra-mantle (deepfocused) earthquakes. Ascertainment of possibilities for practical use of these and accompanying minerals will enrich the list of mineral resources of the world, in particular of Kyrgyzstan.
Researching these questions has a significant scientific and important practical value. In Kyrgyzstan there are three locations (Kyrgyz, Zailiisk, and Atbashy ridges) with eclogite bearing complexes with minerals of high and ultra-high pressure. There is also one location with kyanite-sillimanite type metamorphic complex with minerals of medium pressure. The later one is partially overlapped by metamorphism of andalusite-sillimanite facies series. Researching their relation to each other should enable us to study the evolution of metamorphic processes from subduction of oceanic plates to different stages of continental collisions. Partition of Tian Shan’s metamorphic complexes and their mapping have been done earlier. Results of researches of eclogite bearing complexes are provided in the list of works by Bakirov et al, 1985; Bakirov, 1989; Tagiri, Bakirov, 1990; Tagiri et al, 1996; Puelles, Takasu, 1996; Bakirov, Tagiri, Sakiev, 2002 and others, whereas the results of research kyanite-sillimanite types of metamorphism are listed in the works by Bakorov, Dobrethsov, 1972; Bakirov et al, 1985.
The project implementation will take place at the Institute of Geology of the National Academy of Sciences of the Kyrgyz Republic (IG NAS KR). The institute is a leading scientific institution in Kyrgyzstan, and highly ranked in the Central Asian region on researching metamorphic minerals. It has been conducting scientific researches in the region for more than 60 years (since founding in 1943), sufficiently endowed with scientific equipment, laboratory, chemical and physical basis, located in a good quality building in the center of state capital – Bishkek.
The project will involve the research fellows from the Institute of Geology of NAS KR as well as invited weapon scientists (see list of personnel).
Our collaborators are well known leading scientists from Japan professor Michio Tagiri (Ibaraki University, Mito, Japan) and professor Akira Takasu (Shimane University, Matsue, Japan). As hitherto done we will continue to conduct joint field works (expeditions) and laboratory research of above-mentioned minerals and rocks. The collaborators will assist in researching the minerals with microbore analyzers and in determining radiological age of rocks and minerals.
The project hopes for a assistance and support form ISTC in conducting joint field expeditions in high altitude areas of Tian Shan.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
