Contemporary equilibrium-line altitudes (ELAs) for glaciers in the high mountains of the Himalaya and Tibet have considerable variation because the region is influenced by two major climatic systems (the mid-latitude westerlies and the south Asian summer monsoon) and glaciers are subject to strong topographic controls. Reconstructions of past ELAs based on the former extent of glaciers are nume...

This study presents preliminary results of research on pre-Angkorian canals near the ancient settlement of Angkor Borei in the southern Mekong delta of southern Cambodia. The canals have been mapped by aerial photograph interpretation and investigated in the field by hand auger drilling of two canal traces and trenching of one of these. Luminescence profiling through the canal infill successful...

The characterization of Last Glacial millennial-timescale warming phases, known as interstadials or Dansgaard-Oeschger events, requires precise chronologies for the study of paleoclimate records. On the European continent, such chronologies are only available for several Last Glacial pollen and rare speleothem archives principally located in the Mediterranean domain. Farther north, in continent...

Rock art compels interest from both researchers and a broader public, inspiring many hypotheses about its cultural origin and meaning, but it is notoriously difficult to date numerically. Barrier Canyon-style (BCS) pictographs of the Colorado Plateau are among the most debated examples; hypotheses about its age span the entire Holocene epoch and previous attempts at direct radiocarbon dating ha...

We analyzed the characteristics of white porcelain fired at different temperatures (800, 1200, 1350℃) by measuring changes in thermal luminescence(TL) and multi-wavelength (IR, orange, green, blue, UVA) optically stimulated luminescence(OSL) signal. White 800℃ showed high intensity TL signals over a wide temperature range 100 to 400℃, whereas 1200 1350℃ peaks 210℃. Moreover, OSL 800℃, increased...

During the penultimate glaciation vast areas of the Alps were glaciated, with piedmont glaciers protruding into the foreland. In the easternmost part of the northward draining valleys of the Alps, the glaciers did not reach the foreland, but formed valley glaciers confined by the mountainous terrain. This also applies to the Ybbs valley, where samples for luminescence dating out of glaciofluvia...

Spatially resolved optically stimulated luminescence (OSL) offers a means for rapid assessment of dose distributions in retrospective dosimetry and geochronology. Until recently, OSL imaging systems have largely been restricted to measurements millimetre scale samples; this approach is not well suited applications where the physical process interest operates on centimetre (e.g., depth dependent...
