Subjects of research: paleogene sedimentary formations of Kyzyl Kum.
Purpose of work: comprehensive study of the conditions of deposition and composition of sedimentary formations of Paleogene of Kyzyl Kum with definition of key stages in the evolution of a sedimentary basin, establishing patterns of facies changes in units of time and space and the identification of a genetic connection with the formation of mineral deposits.
Methods of research: stage dynamic principle of facial analysis of sedimentary formations and the complex layering and biorhythmostratigraphical differentiation and correlation of the sections, facial analysis of differentiation of sediment on a range of hydrochemical conditions defining the hydrochemical composition of the water basin, reductive-oxidative and acid-base indicators.
The results obtained and their novelty: identified five stages of evolution of the Paleogene sedimentary basin. It is established that the change of transgressions and regressions of Paleogene marine basin is related to global causes - of eustatic changes in sea level. Clarified biorhythmostratigraphical definition and correlation of Paleogene sections of the region. Selected dynamic facial units. For the first time identified: sulfate-dolomite chemical, calcareous biochemical and bentonite physical-chemical facies, reflecting the specific environmental conditions of sedimentation.
Practical value: opened deposits of alkaline bentonite and carbonate palygorskite clays of Navbahor, white mealy dolomites of Vaush, manifestations opoka clays Kokcha, pelitomorphic dolomites of Amantaytau.
Degree of embed and economic effectivity: on the basis of Navbakhor deposit built a plant of mud powder with capacity of 40 tons per year. Products manufactured by the enterprise are the import- and export-oriented.
Field of application: regional forecast on the basis of stratigraphic, facies, mineral and geochemical criteria, the search and evaluation of deposits of non-metallic materials.
