2 Loess and terrestrial archives

Chair: Markovic, Slobodan ; Zech, Michael ;

Monday, 16:00-17:50,

Loess and loess-like deposits cover about 10% of the Earth’s continents mostly concentrated in the mid latitude zone of Eurasia. These deposits represent one of the world's most outstanding terrestrial archives of climate and environmental change. Attaining considerable thickness and formed under high accumulation rates, they preserve long-term paleoclimate signals that can be analyzed at high resolution to uncover millennial-scale climate changes.

In Europe, the middle and lower Danube basin exhibits extensive loess plateaus formed under ecological conditions which are today prelevant in Central Asia. Outside the areas with loess-plateau facies west and north of the Danube basin spatially and temporally discontinuous loess and loess-like deposits provide nevertheless valuable insights into the Pleistocene environments. In the recent past, substantial progress has been made in chronostratigraphy and in environmental reconstruction of loess deposits using geophysical, sedimentological, biological and inorganic as well as organic geochemical proxies which allow for qualitative and quantitative reconstruction of the environment under which the deposits were formed. Presentations addressing these new developments are highly appreciated.

 Besides loess, other terrestrial archives (e.g., dunes, slope deposits, ....) are relevant for this session. We invite presentations focussing on new methods of loess research and on the European loess belt as well as on other areas and archives.

The session will be held in English language.
