Title: "More cups of tea in Tajikistan and Mongolia: lake-sediment studies, geoarchaeology, and a surprise"
List of Friday seminars of Institute of Earth Sciences and Nordic Volcanological Center
Abstract:
Following Greg’s talk last year, our presentation takes you on another culinary (bring your empty teacup!) road trip in Central Asia. A first sip is offered from Tajikistan: sediment cores from the country’s largest lake, Lake Karakul, were recovered and analysed to reconstruct the environmental and climate history of the last 31,000 years. Sedimentological, geochemical and palynological data suggest that the level of the closed-basin lake was highest before ca. 26,000 years and between 17,000 years and the early Holocene. Stable isotope analyses of fine-grained carbonate and ostracod (micro-crustacean) valves are still ongoing with the aim to prepare a continuous climate record with a 50-years resolution. Additional teacups are accompanied by presented results of completed and newly started research projects in central and western Mongolia.
Bring your empty teacup to try some Middle/Central Asian wonders of refreshing cold and hot beverages.
All are welcome.
