Climate: Past, Present & Future

Christian Zeeden

Christian Zeeden is a (cyclo)stratigrapher and geophysical sedimentologist at the Leibniz Institute for Applied Geophysics (LIAG, Hannover, Germany). His research includes sedimentology and stratigraphy of aeolian terrestrial deposits as palaeoclimate and geoarchaeological archives. He applies and advances cyclostratigraphy as part of an integrated stratigraphical approach. His research includes geological time series analysis and statistical programming, and focuses on terrestrial sediments and recorded climate cycles both as stratigraphical information as well as palaeoclimatic archive.

What’s my age again? Comparing dating methods in loess

What’s my age again? Comparing dating methods in loess

As you have learned from our previous posts, loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, such as luminescence dating, radiocarbon dating, magnetic stratigraphy, and or ...[Read More]

Desert loess: formation, distribution, geoscientific value

Loess is an aeolian (wind-driven) silty sediment covering over 10% of the Earth’s land surface; it occurs predominantly in the mid-latitudes. On a global scale, loess is among the most widespread unconsolidated sediments, and of crucial importance for agricultural regions where loess deposits are known to form fertile soils because of its ability to store water and retain nutrients. Loess is compr ...[Read More]
