Most rifts consist of a series of separate segments that together form the linear zone characteristic of rifts. The individual rift segments have a dominantly half-graben geometry, controlled by a single basin-bounding fault. Segment lengths vary between rifts, depending on the elastic thickness of the lithosphere. Areas of thick colder lithosphere, such as the Baikal Rift have segment lengths in exc… WebMay 20, 2024 · The Baikal Rift Valley (sometimes called the Baikal Rift Zone) cuts through 2,000 kilometers (1,200 miles) of Siberia, in eastern Russia.
