英文摘要: Lake Baikal sedimentary records in general and magnetostratigraphy in particular have already enormously contributed in the global context to evaluate environmental and climatic changes in the deep continental setting. The Baikal Drilling Project (BDP) has become a world leader in pioneering recovery of extremely long (several hundred meters) lacustrine sediment sequences from deep water. This has made it possible, for the first time, to obtain a continental archive with the same chronostratigraphic integrity as marine records to address critical questions of the last eight million years. It explains why the amount of publications on Lake Baikal sedimentary and magnetic records can be compared to the number of papers for the Oceanic Drilling Program. The unique continuity of the Lake Baikal deep drilled cores — short piston cores and deep drilled cores — of 1993, 1996, and 1998 enables one to reconstruct reliably the geomagnetic polarity chrons and a number of the shorter geomagnetic events. Data from three very long cores allows a comparison to the geomagnetic polarity time scale (GPTS) and detailed records of geomagnetic events in the last 8.4 Ma. A refined age model, supported by 10Be dates, provides constraints for the short geomagnetic events. Some geomagnetic events are correlated with geomagnetic excursions already discussed in the literature; others are identified for the first time and may need future confirmation. © 2017 Elsevier B.V.
