An understanding of the spatio-temporal evolution of Eurasian climate through the Quaternary requires comparable datasets as a very basic prerequisite.
Here the standing inconsistency of time scales of Eurasian loess is initially outlined; numerous authors interpret soil formation phases in Eurasia in different ways, leading to different timing of related soil formations. Based on this issue, a personal view on the challenge of obtaining correlative age models with highlight on MIS 3 is given, and suggestions for a correlative age model based on northern hemisphere reference records are made. Ice models (as e.g. the Imbrie & Imbrie 1980 model) can explain several features seen in loess records, which deviate from most marine records and insolation. Using a combination of marine data and the Imbrie & Imbrie 1980 ice model, a proposal for the time scale of magnetic enhancement in loess-paleosol sequences is given. It needs to be noted that although such a correlation is useful for most records, but exceptions may exist especially for the timing of the S1 roughly related to MIS 5.
