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...

We performed seismoacoustic and magnetic investigations of samples taken from Lake Bolshoe Miassovo (Chelyabinsk region, Russia) in 2018. Before sampling, seismoacoustic investigations were conducted in order to study stratification in sediments, reconstruct the reservoir?s history and select core locations with undisturbed stratification. A special hydraulic corer was used for taking long core samples. Five cores up to 5 meters long were obtained. For laboratory investigations, all cores have been cut into smalle...
