Аннотация

The study of the geochemical and mineral composition of the bottom sediments of Lake Onega (the Petrozavodsk Bay) described fundamental differences between the chemical composition of sediments formed at the Holocene and Upper Pleistocene. It suggested the reason for mechanical to chemical type of weathering.
