摘要
Based on published procedures, a modified procedure for 10Be and 26Al exposure dating was developed, which includes 10Be and 26Al extraction, anion exchange column separation, purification and target preparation. The ICP-AES results indicated the recoveries of Be and Al were 90% and 60%, respectively. One sample from Jinfosi site, northern Qilianshan Mountains, was tested based on this procedure. The dating results of (10.7±1.0) ka for 10Be and (10.0±1.2) ka for 26Al, were consistent with published geological results
