Variations in environmental conditions of intracontinental Asia over the past 1 Ma in high-resolution geochemical records from bottom sediments of Lake Khubsugul (Mongolia)

A study reports the first detailed data on the distribution of trace and major elements in Pleistocene sediments of Khubsugul, as well as interpretation of geochemical variations as reflections of environmental variations in Inner Asia. Data indicate that events in the Khubsugul geochemical record d...

Summary:A study reports the first detailed data on the distribution of trace and major elements in Pleistocene sediments of Khubsugul, as well as interpretation of geochemical variations as reflections of environmental variations in Inner Asia. Data indicate that events in the Khubsugul geochemical record described above might be a component of a common 400- to 500-ka-long cyclic evolution of the environment. At the same time, inner climatic peculiarities of these cycles were extremely diverse in different continental systems.
