On the palaeoclimatic structure of MIS-5 analogues in the midland part of Siberia (palaeobotanical and U/Th dating data)
A simultaneous use of 14C, U/Th dating and palaeobotanic researches of the midland part of Western and Middle Siberia (Shurishkary, Gornaya Subbota, Golden Cape, Chembakchino and Bedoba) has allowed to trace a correlation of the palaeoclimatic events detected in these sections with similar events fi...

A simultaneous use of 14C, U/Th dating and palaeobotanic researches of the midland part of Western and Middle Siberia (Shurishkary, Gornaya Subbota, Golden Cape, Chembakchino and Bedoba) has allowed to trace a correlation of the palaeoclimatic events detected in these sections with similar events fixed in the ice-core of Greenland (SUMMIT) and MIS-5.
