黄土是第四纪时期最重要、最典型的陆相碎屑沉积物,黄土石英中“就地成因”10Be/26Al的浓度可望应用于黄土地层定年。黄土石英中就地生成的10Be浓度很低,需要相当高的测量灵敏度。
Loess is the most important and typical terrigenous clastic sediments in the Quaternary period. The concentrations of 10Be / 26Al in loess quartz are expected to be applied to the loess strata dating. The concentration of 10Be generated in situ in loess quartz is low, requiring a very high measurement sensitivity.
