摘要
It was previously thought that the Huanglianguan Formation was formed in the late period of late Pleistocene and was composed of alluvial deposits. Seven samples from Huanglianguan Formation were dated using the OSL dating method. One of the results was abandoned because of its poor reliability. The OSL ages of the samples are from （143.3±21.4）ka to （87.4±8.7）ka. The results obtained indicate that the Huanglianguan Formation was formed at least in the early Late Pleistocene period in a warm and wet climate environment of the last interglacial period.
