- Abstract
- The loess-paleosols deposits in the Chinese Loess Plateau are a huge archive of a continuous record for paleoclimates. These loess-paleosols sequences have long been studied and correlated with modelled paleoclimates. However, measured soil data would not be straightforward to identify relations between modelled paleoclimate intensity and paleosol development, as five key soil-forming factors drive soil formation (“CLORPT”): Climate, Organisms, Relief, Parent material and Time. Therefore, not only the past climate (precipitation, temperature) has an effect on soil development, but also vegetation, interglacial duration and dust deposition play a vital role. Additionally, observed soil parameters may have been affected by pedogenetic overwriting in later periods. Therefore, we combine a dynamic climate and –soil model to identify important drivers for paleosol development. The intention of this research study is to identify the relative importance of soil-forming factors (temperature, precipitation, vegetation, interglacial duration and dust deposition) on soil development during each of the Quaternary intergalcials (MIS-1, MIS-5, MIS-7, MIS-9, MIS-11 and MIS-13) over the past 500 kyr in the Chinese loess-paleosol sections.
