Cosmogenic nuclide burial dating of Liuwan Paleolithic site in the Luonan Basin, Central China
The Luonan Basin is a key region of early human settlement in Central China with more than discovered Paleolithic sites. Artifact layer 1 of the Liuwan site was dated to approximately 0. We determined the burial age of artifact layer 1, which was most likely at least 0. The new burial age confirmed the previous estimated age and provided a considerably accurate age range.

Aluminium helps date solar system
The interaction of cosmic radiation with terrestrial matter leads to the in-situ production of cosmogenic nuclides in the exposed surface material. Accelerator mass spectrometry AMS enables us to quantitatively measure trace concentrations of in-situ produced radionuclides like 10 Be and 26 Al. This ultimately allows the determination of surface exposure ages, erosion rates and other processes of landscape evolution.
The availability of a pure and well defined mineral sample is an important prerequisite for surface exposure dating.
Diarmad G. N2 – We successfully apply exposure dating using cosmogenic nuclides to natural terrain landslides in Hong Kong. Forty-five samples from eight landslide sites were exposure dated using 10Be, and a subset of six samples was also dated using 26Al. The sites comprised four large, deep-seated landslides featuring well-preserved rock scarps and associated debris lobes; two sites of rock and boulder fall; and two sites where scarps only are preserved.
Exposure ages from the deep-seated landslide scarps generally gave the most internally consistent ages for the landslides. However, only in rare cases did the landslide scarp ages overlap with those of boulders in the associated debris. Generally, boulders in the debris appeared to contain significant inheritance of cosmogenic nuclides from previous exposure and so yielded ages greater than those from the scarps.
This study has shown that it is possible to measure exposure ages of surfaces associated with large landslides from 70, yr down to a few thousand years old, despite low cosmogenic isotope production rates in Hong Kong due to low latitude and low altitude. AB – We successfully apply exposure dating using cosmogenic nuclides to natural terrain landslides in Hong Kong.
Cosmogenic 10Be and 26Al dating of paleolake shorelines in Tibet
ABSTRACT: This paper presents results of the analysis of paired cosmogenic isotopes (10Be and 26Al) from eight quartz-rich samples collected from.
Assessment of vertical movements of tectonically bounded blocks is crucial for determination of geohazards in densely inhabited zones, such as the border zone of western Slovakia and eastern Austria. The structural research revealed predisposition of forming of horizontal passages in low angle to subhorizontal bedrock stratification together with low-grade metamorphic foliation. Fluvial origin of the passages was inferred from mezoscale erosional features on the bedrock as well as from facies character of the well preserved sedimentary profile.
Three analysed dating samples provided low values of isotopic concentrations, allowing us only to calculate the minimum burial age of the deposit of 1. The slow incision of the river network. In contrast are relatively high values of palaeodenudation rates inferred from isotopic concentrations. Strukturna raziskava je razkrila predispozicijo oblikovanja vodoravnih jamskih rovov pod nizkim kotom v odvisnosti od subhorozontalne stratifikacije kamnine ter tudi z nizko stopnjo metamorfne foliacije.

Only the ages of lower terraces were previously delimited by 14C. The highest elevation terraces T 8 , T 9 were sampled for cosmogenic 26AlBe burial dating to delimit the ages of previously identified faults, and possibly locate evidence of faults that may displace the terraces. Samples were collected from four locations 5 samples in each location, 20 samples total on both the north and south sides of the reservoir near previously identified faults.

Long-term slip rate of the southern San Andreas Fault from 10BeAl surface exposure dating of an offset alluvial fan. Journal of Geophysical Research, A total of 26 quartz-rich cobbles from three different fan surfaces were collected and dated. The tight cluster of nuclide concentrations from 19 samples out of 20 from the offset fan surface implies a simple exposure history, negligible prior exposure and erosion, and yields an age of

Descaretes, Strasbourg Cedex. Late Pleistocene—Holocene sinistral slip-rates on several segments of the Kunlun Fault in northeastern Tibet have been determined. These determinations are based on the measured displacement of alluvial surfaces whose surface ages were determined by cosmogenic 26 Al and 10 Be dating of quartz pebbles, and by 14 C dating of charcoal. Farther east, near The slip-rates are constant, within uncertainty, throughout the km of the Kunlun Fault that we studied.
The average slip-rate is Extrapolating this rate to the reminder of the fault, we conclude that most 80 per cent of the morphological offsets measured in the field or on SPOT satellite images post-date the Last Glacial Maximum. Most of the terraces we studied were deposited during the humidperiod of the Early Holocene Optimum 9—5 ka ; the formation of younger terraces reflects Late Holocene climate change.
Their great lateral extent and spatial relationship to high-angle shortening features large thrusts and growing mountain ranges suggest that they play a major role in accommodating Indo-Asian convergence e.

Paleoclimatic constraints from regions at the confluence of major climate systems are particularly important in understanding past climate change. Using geomorphic mapping based on remote sensing and field investigations, combined with in situ cosmogenic 10Be and 26Al dating of boulders associated with glacial landforms, we investigate the chronology of past glaciation in the Inylchek and Sary-Dzaz valleys in the eastern Kyrgyz Tian Shan, a tectonically active area with some of the highest peaks in the world outside of the Himalayas.
The evidence for glacial extent in this study is consistent with a limited ice expansion hypothesis for Tian Shan glaciation. Published results from the western and central Kyrgyz Tian Shan do not show evidence for significant LGM glacier expansion, which in combination with the results presented here, indicate a spatial variation in glacier records along the Tian Shan.
This may reflect either paleoclimatic gradients or the impact of local physiographic conditions on responses to regional climate change, or both.

This proposal seeks funding for measurement of the cosmogenic radionuclides 26Al and 10Be in quartz from core and outcrop of Plio-Pleistocene sediment within and near Unaweep Canyon. The Plio-Pleistocene sediments were newly mapped in , and the core was collected in Our preliminary data indicate that Unaweep Canyon is a Paleozoic landform buried by later Paleozoic and Mesozoic sediments and then re-exhumed during the Cenozoic, a controversial claim.
Despite considerable age-dating efforts in our previous research, we have found no material in this sedimentary succession that can be dated using conventional methods. Thus, the purpose of this proposal is to apply newly developed methods of? Successful dating of the target sediments will yield three tangible benefits. First, it will solve a significant regional geologic problem by establishing the timeline of geomorphic events and will yield insight into the rate and nature of Cenozoic fluvial incision of the Colorado Plateau?
Second, it will help to move a newly developed dating method from the developmental stage into practical applications. This work will also result in significant broader impacts, including strengthening interdisciplinary collaborations, exposing students to cutting-edge techniques, and disseminating the research via publication and classroom use.
