冰碛物测年是冰川地质环境重建的基本要求.由于冰碛物含碳量太低,本文用加速质谱计(ＡＭＳ)对天山乌鲁木齐河河源末次冰期以来的羊背石上和冰碛物中的同生和次生碳酸钙进行无机碳测年,以期为解决我国长期以来冰川沉积物测年难题提供一条途径.(1)采样区概况 天山乌鲁木齐河河
The dating of the moraines is the basic requirement for the reconstruction of the glacier geological environment.Because the carbon content of the moraine is too low, this paper uses accelerated mass spectrometry (AMS) Inorganic and secondary carbon dating of syngenetic and secondary calcium carbonate in order to provide a way to solve the long-term glacial sediment dating problems (1) Overview of the sampling area Tianshan Urumqi River
