摘要:Abstract(#br)Deep-seated gravitational slope deformations (DSGSDs) are complex slope instabilities commonly involving long-term evolution with significant spatial and temporal variations in slope kinematics. The Cerentino compound landslide in southern Switzerland exemplifie...

摘要:Abstract(#br)Meteoric 10 Be is commonly used as a geochemical tracer of soil erosion and regolith residence time over long time scales (> 10 3 yr). The acidic conditions of tropical soils are less favorable for meteoric 10 Be retention, and make a translation of meteoric 10 Be i...

摘要:Abstract(#br)In 2012, Miyake et al. reported a sudden and strong increase of the atmospheric radiocarbon ( 14 C) content in Japanese cedar trees of 1.2% between AD 774 and 775. While their findings were quickly confirmed by a German oak chronology for the Northern Hemisphere...

摘要:Abstract(#br)The topographic signature of a mountain belt depends on the interplay of tectonic, climatic and erosional processes, whose relative importance changes over times, while quantifying these processes and their rates at specific times remains a challenge. The eastern And...

摘要:Abstract(#br)In this paper we present the first comprehensive analysis of the 1 MV AMS system at the Centro Nacional de Aceleradores (CNA, Seville, Spain) for 236 U studies in environmental samples. In the last years, this radionuclide has become key in the AMS community, du...

摘要:Abstract(#br)The motivation of this work is to establish a new multi-isotope plutonium standard for isotopic ratio measurements with accelerator mass spectrometry (AMS), since stocks of existing solutions are declining. To this end, certified reference materials (CRMs) of each of...

摘要:Abstract(#br)Terrestrial cosmogenic nuclide exposure ages for the Wohlthat Massif (Antarctica), have previously been determined. This was done with 10 Be and 26 Al measurements by accelerator mass spectrometry (AMS) at the AMS facility at the ETH Zurich.(#br)In order to dete...

摘要:Abstract(#br)The first dataset of 236 U/ 238 U in the water column of the Arctic Ocean (AO) is presented and shows the widest range of ratios reported so far in the open ocean, from ( 5 ± 5 ) to ( 3840 ± 260 ) × 10 − 12 . Surface samples and depth profiles were collecte...

摘要:Abstract(#br)A hominid tooth found in a river terrace layer from Azmaka (Bulgaria) has been biochronologically dated to ∼7 Ma. This age is younger than expected and indicates that hominids became extinct in Europe later than previously thought. In this study, authigenic 10 B...

摘要:Abstract(#br)The possibility that galactic cosmic rays (GCR) influence the Earth's cloud cover and therefore have an important impact on the Earth's radiative climate forcing has become a leading candidate to explain the observed sun–climate connection. A correlation between...
