Some issues to be considered in establishing age models for the long Lake Baikal sediment records

Abstract The middle part of core BDP98 from Lake Baikal, which contains the oldest lake sediments ever obtained in the world from an existing lake, is structurally different from other parts of the core. Age models that disregard this difference are of little meaning. This part of the core must be examined and discussed in detail if we are to propose physically reasonable models for dating this long terrestrial record from Lake Baikal.
