Abstract

We briefly report the history of studying Baikal gas hydrates, their discovery in the areas of new structures, and the specific composition of Baikal hydrate-containing subsurface sediments. The structures with a volcanic breccia were referred to as mud volcanoes. The first geological search criteria for the presence of gas hydrates in the Baikal subsurface sediments are presented.
