Session Description
Loess records blanket 10% of the Earth’s land surface and constitute some of the most continuous Quaternary sediments on land, providing invaluable archives of environmental and climatic variability. Two critical components underpin loess palaeoclimatic reconstruction: 1) precise and accurate chronologies, and 2) the development and application of reliable proxies that elucidate specific environmental or climatic parameters, such as temperature, precipitation, wind dynamics and vegetation assemblages. This session focusses on recent advances in proxy development and chronological methodologies for quantitative reconstruction of Quaternary climatic and environmental change. Breakthroughs in magnetic analysis, stable isotope studies (including clumped isotopes), biomarker investigations, palaeoecology, paleopedology and provenance methods are encouraged. Submissions addressing dust flux estimation through absolute dating from loess deposits are especially welcome.
