Аннотация

Subjects of the inquiry: holoccnc sediments in the basin Chirchik. Aim of the inquiry: To establish the characteristics of spatial-temporal structure of the geomagnetic field through the holoccnc palcomagnctic study of sections of the river basin Chirchik and drafting magnetostratigraphy scheme of Holoccnc sediments in the region Methods of inquiry: magnetostratigraphy holoccnc on the basis of integrated field and laboratory palcomagnctic studies. The results achieved and their novelty: For the first time the continental deposits of the holoccnc basin Chirchik by magnetostratigraphy studies modeled the structure of the geomagnetic field of the Holocene, the scheme magnetostratigraphy subdivision and correlation of the studied sections and the correlation magnetostratigraphy scheme. Age characteristics of short-term deviations of the holocene dates the gcomorphological levels of terraces and use them for palcogcographic reconstruction of extensive regional coverage and linkage with paleoclimatic and archaeological data. Practical value: Established stratigraphic levels of short-term geomagnetic events of the holocene, which determine the palacomagnctic reference frame for the studied sediments and allows their use magnetostratigraphy dismemberment of holocene sediments for geological and stratigraphic problems, the implementation of the correlation, the development of the regional stratigraphic scheme of continental holocene formations on the territory of Uzbekistan. Degree of embed and economic effectivity: The results of the study in the State Committee of Uzbekistan on Geology and Mineral Resources and the learning process of the geological department NUU named after Mirzo Ulugbek implemented. Studies have considerably strengthened the stratigraphic base of subdivision and correlation of holocene sediments, which ultimately enhances the effectiveness of geological prospecting, geological survey work and research of engineering geology. Sphere of usage: Quaternary geology, stratigraphy, geomorphology, paleogeography, paleomagnetism, palcoclimatology, archeology.
