Tectonic Lakes

Lakes formed by large scale crustal movements separating water bodies from the sea ate tectonic lakes, e.g the Aral and Caspian Seas. Lakes formed in rift valleys by earth faulting, folding or tilting, such as the African Rift lakes and Lake Baikal , Russia. Lakes in this category may be exceptionally old. For example, the present day Lake Baikal originated 25 million years ago.
