Optically stimulated luminescence dating of young glacial sediments from the eastern Qinghai-Tibetan Plateau
Poor bleaching is a significant problem for Optically Stimulated Luminescence（OSL） dating of glacial sediments. Five young glacial samples（including two modern analogues） from different depositional settings were collected beyond the Yingpu Glacier in the eastern Qinghai-Tibetan Plateau. De was dete...

| description | Poor bleaching is a significant problem for Optically Stimulated Luminescence（OSL） dating of glacial sediments. Five young glacial samples（including two modern analogues） from different depositional settings were collected beyond the Yingpu Glacier in the eastern Qinghai-Tibetan Plateau. De was determined using different OSL methods. The luminescence characteristics and dating results showed that the large aliquot quartz Blue Stimulated Luminescence（BSL） is more applicable than polymineral infrared stimulated luminescence（IRSL） method. Small aliquot quartz BSL results showed poor luminescence properties due to low luminescence sensitivity of quartz in this area. The dating results also indicated that glaciofluvial samples deposited close to ice margin（~40 m and ~700 m） and supraglacial debris dominated lateral moraine samples are relatively well-bleached, whereas samples from ground moraine and low terminal moraine were poorly bleached, probably due to containing subglacial and englacial debris. The residual doses of glaciofluvial and lateral moraine crest samples were below a few Gy and age overestimations were below a few hundred years. The ground moraine and low terminal moraine samples had residual doses as high as ~110 Gy, and ages were overestimated by ~15-17 ka. |
