Unlinking erosion from uplift in Tibet Conventional wisdom suggests that the locations of gorges or “knickpoints” along edges large plateaus remain fixed because drives tectonic uplift. Nowhere should this be more evident than rapidly uplifting and eroding Tibetan plateau. However, King et al. found evidence for slow migration a major knickpoint Parlung River eastern Tibet. They used new method with exceptional time resolution determining regional cooling rates called multi–OSL (optically...
Abstract A transformative advance in Earth science is the development of low‐temperature thermochronometry to date surface processes or quantify thermal evolution rocks through time. Grand challenges and new directions involve pushing boundaries these techniques decipher histories operative over seconds hundreds millions years, recent deep geologic time from perspective atoms mountain belts. Here we highlight innovation bedrock detrital fission track, (U–Th)/He, trapped charge...
A universal multistage cascade CSTR has been developed that is suitable for a wide range of continuous-flow processes. Coined by our group the "Freactor" (free-to-access reactor), new reactor integrates efficiency pipe-flow processing with advanced mixing CSTR, delivering general "plug-and-play" platform which well-suited to multiphasic chemistry. Importantly, geometry easily customized accommodate reactions requiring long residence times (≥3 h tested).
Abstract Paleoclimate records from the Atacama Desert are rare and mostly discontinuous, mainly recording runoff Precordillera to east, rather than local precipitation. Until now, paleoclimate have not been reported hyperarid core of (<2 mm/yr). Here we report results multi-disciplinary investigation a 6.2 m drill retrieved an endorheic basin within Coastal Cordillera. The record spans last 215 ka indicates that long-term climate in Central witnessed small but significant changes...
Abstract Constraining the timescales of sediment transport by glacier systems is important for understanding processes controlling dynamics within glacierized catchments, and because accumulation supraglacial influences response to climate change. However, glacial can be difficult observe; transported englacially, subglacially, supraglacially or at ice margins, may stored temporarily on headwall slopes moraines before being (re‐)entrained ice. This study a proof concept use luminescence rock...
Abstract Since the Last Glacial Maximum, ∼20 k.y. ago, Alpine glaciers have retreated and thinned. This transition exposed bare bedrock surfaces that could then be eroded by a combination of debuttressing or local frost cracking weathering. Quantification respective contributions these processes is necessary to understand links between long-term climate erosion in mountains. Here, we quantified histories postglacial glacial valleys. Combining optically stimulated luminescence terrestrial...
Arsenic contamination in groundwater is pervasive throughout deltaic regions of Southeast Asia and threatens the health millions. The speciation As sediments overlying contaminated aquifers poorly constrained. Here, we investigate chemical mineralogical compositions sediment cores collected from Mekong Delta Vietnam, elucidate iron arsenic, relate them to depositional environment. Gradual dissolution ferric (oxyhydr)oxides with depth observed down 7 m, corresponding establishment reducing...
The optically stimulated luminescence (OSL) signals of quartz and K-feldspar are known to bleach poorly within some glacial settings, can present a major challenge dating applications. However, because the OSL signal is extremely sensitive sunlight exposure history, residual modern sediments also encode information about transport depositional processes. Through examination properties (equivalent dose (De) overdispersion values) suite from different settings (sandar, proglacial delta main...
During the Quaternary period, eastern Sahara's hydroclimate oscillated between wet and dry intervals. These oscillations caused drastic changes in precipitation rates, often associated with ancient human migrations. In particular, significant migration of riparian populations from Nile Valley to west northwestward Sahara occurred during African Humid Period (AHP), an episode increased monsoons, which characterized North Africa response increasing insolation. Several fossil rivers, now...
Abstract. The electron spin resonance (ESR) of quartz has previously been shown to have potential for determining rock cooling histories; however, this technique remains underdeveloped. In study, we explore the ESR a suite samples from Hida range Japanese Alps. We develop measurement protocols and models constrain natural trapped-charge concentration as well parameters that govern signal growth thermal decay. stability Al Ti centres is similar luminescence feldspar. Inverting data yields...
Low-temperature thermochronology dates mineral cooling through the upper crust, enabling us to constrain rate and timing of landscape evolution over a range spatial-temporal scales (Reiners et al. 2005). However, constraining recent thermal histories timescales 105&#8722;106 years at temperature ranges between 25 75 oC remains challenge owing lack temporal resolution from existing thermochronometers. Deciphering time-temperature (
