Surface exposure dating
The second main part of the work contains the detailed results from the chosen study areas, presented separately in four chapters.Finally, a synthesis about the calculated former ELAs and the conclusions put the regional findings together to gain a more general outline for both, geochronological and methodological aspects.The results in the present study indicate that the PVF was active in the last 5 ka. Linking the past athmospheric circulation pattern to terrestrial climate proxies is essential for an understanding of climate-glacier interaction.A good part of the section of the book is dedicated to the problems of calibration and age interpretation of the results.Reuther stresses the possible influence of site-related factors (e.g.We modeled the variation of Be concentrations with depth down into the sediment in which the first (exhumed) boulder was once buried in, and down into the third (quarried) boulder.
This allows the reader to make his own opinion about the potential errors and precision of the dates presented, and delivers some practical solutions for those readers applying SED using TCN by themselves.Recent studies on the Llancanelo Volcanic Field (LLVF) and PVF have determined volcanic activity mainly using K-Ar and 40Ar/39Ar as well as cosmogenic 3He.However, K-Ar and 40Ar/39Ar fail to produce reliable ages in Holocene basaltic flows. Glacial deposits constitute an important terrestrial record of climate change. appendix, 17x24cm, 600 g Language: English (Relief Boden Palaeoklima, Band 21) ISBN 978-3-443-09021-0, paperback, price: 68.00 € in stock and ready to ship Bib Te X file A major research goal in Quarternary sciences today is the reconstruction of past glacial fluctuations.
