The timing of past glaciation across the Tian Shan provides a proxy for climate change in this critical area. Correlating glacial stages region is difficult but cosmogenic exposure ages have considerable potential. A drawback large observed scatter 10Be surface data. To quantify robustness dating, we compile, recalculate, and perform statistical analyses on sets from 25 moraines, consisting 114 new previously published ages. We assess boulder age by dividing groups into quality classes...
In this article, we present a map of the glacial geomorphology Altai and Western Sayan Mountains, covering an area almost 600,000 km2. Although numerous studies provide evidence for restricted Pleistocene glaciations in area, others have hypothesized past existence extensive ice sheet. To framework accurate reconstructions at scale 1:1,000,000 based on mapping from 30 m resolution ASTER DEM 15 m/30 Landsat ETM+ satellite imagery. Four landform classes been mapped: marginal moraines,...
Extensive glacial lakes dammed in the Scandinavian Mountains during retreat of last Ice Sheet were first hypothesised over a century ago. Here, using high-resolution LiDAR, we report >4500 relict shorelines, deltas and palaeo-channels related to ice-dammed ∼30 000 km2 area central Jämtland, west-central Sweden. Shorelines occur as flights on valley sides, consequence sequential lowering palaeo-lake levels ice margin lower threshold outlets becoming ice-free. Based extent elevation identify...
The Southern part of the Russian Altai Mountains is recognized for its evidence catastrophic glacial lake outbursts. However, little known about late Pleistocene paleoglacial history, despite interest in such reconstructions constraining paleoclimate. In this study, we present a detailed paleoglaciological reconstruction Chagan Uzun Valley, Mountains, combining first time geomorphological mapping, sedimentological logging, and situ cosmogenic 10Be 26Al surface exposure dating...
ABSTRACT Previous investigations observed a period of major glacial advances in Central Asia during marine oxygen isotope stage (MIS) 3 (57–29 ka), out phase with global ice volume records. We have re‐examined the Kanas moraine complex Altai Mountains Asia, where an MIS glaciation had been previously inferred. New and consistent cosmogenic exposure single‐grain luminescence ages indicate that was formed 2 (29–12 which brings its timing line record. also identified lateral from more extensive...
ABSTRACT Reconstructing the response of present-day ice sheets to past global climate change is important for constraining and refining numerical models which forecast future contributions these sea-level change. Mapping landforms an essential step in reconstructing glacial histories. Here we present a new map deposits on nunataks western Dronning Maud Land, Antarctica. Nunataks are mountains or ridges that currently protrude through sheet may provide evidence they have been wholly partly...
This study provides mapping of glacial and fluvial geomorphology in the Shaluli Shan region on eastern margin south-eastern Tibetan Plateau. Based TanDEM-X 12 m elevation data GoogleEarth imagery, valleys, ice-marginal moraines, lineations, scoured terrain terraces were mapped. Covering around 11,000 km2, this map is first for to display at a spatial resolution 0.4 arcsec (= c. 11 m) include terraces. Its landform distribution largely consistent with previous mapping. The substantially...
