MAIN RESULTS OF GEOLOGICAL STUDIES OF PROCESSES RELATED TO THE HYDROCARBON MIGRATION IN THE LAKE BAIKAL WATER AREA

A general assessment of geology of the Lake Baikal basin is given. Issues related to the methodology and main results of studying hydrocarbon migration processes in the central environmental zone of the Baikal natural area from 2015 to 2020 are discussed. Extensive material has been obtained on geology of the upper part of the section of recent sediments, geochemical, physicochemical and other features of the near-bottom area of the lake. An electronic atlas of 1:1M maps of the central ecological zone of the Baikal natural area and an electronic catalogue of hydrocarbon occurrences and their discharge zones were compiled. The high efficiency of combining various geological methods for identifying, studying and monitoring sites of natural hydrocarbon migration is shown.
Keywords: Lake Baikal, hydrocarbon, methods of geological studies.
