The paper considers the features of the sedimentation of the lakes of the Southern Urals, Bolshoi Kisegach and Turgoyak. Previous studies shows that micrometeorites and cosmic dust can be found in different types of sediments and rocks and also magnetic properties can be used for choosing reliable samples for further investigations. Morphology and elemental composition of 5 magnetic separates studied using scanning electron microscopy in the Interdisciplinary Center for Analytical Microscopy of the KFU on the fiel...

In this study we did complex investigations sediments of lake Maloe Miassovo (Chelyabinsk region, Russia). Seismic explorations allowed characterized the sedimentation mass and find the best sites for core samples collection. Four core samples collection were taken with the use of hydraulical core extractor. The maximum core length was 5.08 m. For investigations in laboratory all cores divided into samples, step of cutting is 2 cm. The magnetic properties of lake sediments were studied on the basis of magneto-mine...
