为研究青藏高原东北部晚第四纪黄土-古土壤的物质来源及记录的环境变化过程，于2012年至2016年在研究区较大的空间范围内采集了黄土、古土壤、风成砂等样品，并于2013年9月在青海湖东岸的种羊场（ZYC）、2019年8月在青海湖北岸的刚察县（GC）和热水村（RS）采集了黄土剖面样品。经过标准的XRF测试，得到青藏高原东北部晚第四纪黄土-古土壤元素组成数据集。
\n该数据集包括：\n（1）青藏高原东北部小于75μm组分的黄土-古土壤元素组成数据（ELE_NETP_LP）；\n（2）ZYC剖面的黄土-古土壤元素组成数据（ELE_NETP_ZYC）；\n（3）GC剖面的黄土-古土壤元素组成数据（ELE_NETP_GC）；\n（4）RS剖面的黄土-古土壤元素组成数据（ELE_NETP_RS）。数据集存储为.xlsx格式。该数据集可为青藏高原东北部黄土-古土壤的物质来源及记录的环境变化过程提供数据支撑。

After standard XRF tests, a dataset of Late Quaternary loess-paleosol elemental compositions was obtained for the northeastern Tibetan Plateau.
\nThe dataset comprises the following components:\n
(1) Elemental composition data of the ＜75 μm fraction in loess-paleosol sequences from the northeastern Tibetan Plateau (ELE_NETP_LP);\n
(2) Elemental composition data of the ZYC loess-paleosol profile (ELE_NETP_ZYC); \n
(3)Elemental composition data of the GC loess-paleosol profile (ELE_NETP_GC);\n
(4) Elemental composition data of the RS loess-paleosol profile (ELE_NETP_RS).The dataset is archived in Microsoft Excel (.xlsx) format and provides critical data support for investigating the provenance of loess-paleosol sequences and reconstructing environmental change processes recorded in these deposits across the northeastern Tibetan Plateau.
