Summary: Based on the fact that eight global glacial-interglacial cycles are identified in the Brunhes Chron from the deep-sea oxygen isotope records, it is shown that the discrepancies in the number of glacial cycles determined from the deep-water and terrestrial paleoclimatic records largely come from the loess sequences of different regions. An incomplete geological record, the uncertain position of the Matuyama-Brunhes geomagnetic reversal in the geological sequence, and insufficiently correct identification of the climatic rank of the corresponding warmings and coolings are the most probable sources of this inconsistency. A consistent systematic approach applied in the integrated investigations of the loess-soil sequences is likely to yield the solution to these problems. The guidelines are suggested for the paleomagnetic studies focused on the most accurate location of the Matuyama-Brunhes reversal in the loess sequences. Copyright 2015 Pleiades Publishing, Ltd.
