Initial substantiation and subsequent perception of hypotheses on structure and development of the Baikal system of basins

The history of getting ideas on the structure and development of the Baikal system of basins and its most important structural elements is conventionally divided into stages of putting forward: 1) initial hypotheses that appeared before the 1960s, 2) numerous hypotheses associated with a large amount of work performed in connection with the development of the rifting problems in the south of Eastern Siberia in the 1960–1990s, and 3) latest hypotheses that resulted from new facts obtained through new approaches implemented in geological studies of the 2000–2020s.
