摘要:

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—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-古土壤剖面样品。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。该数据集包括:(1)青藏高原东北部小于75 μm组分的黄土-古土壤元素组成数据(ELE_NETP_LP);(2)ZYC剖面的黄土-古土壤元素组成数据(ELE_NETP_ZYC);(3)GC剖面的黄土-古土壤元素组成数据(ELE_NETP_GC);(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。本数据集的相关研究成果发表在《中国沙漠》2020年第40卷第6期,《Quaternary International》2021年第580卷和《沉积学报》2021年第39卷第5期。

Abstract:

In order to study the source area and paleoenvironmental implication of the late Pleistocene loess and paleosol deposits on the northeastern Tibetan Plateau (NETP), samples of loess and paleosol in this study area have been collected from 2012 to 2016. In addition, typical sections of loess and paleosol deposits have been sampled for ZYC section in east shore of Qinghai Lake in September 2013, GC section and RS section in north shore of Qinghai Lake in August 2019. By method of X-ray fluorescence spectrometry (XRF), the preliminary dataset of elemental compositions of loess and paleosol deposits on the NETP has been constructed. This dataset includes four group files: (1) elemental compositions of loess and paleosol deposits (less than 75 μm fractions) on the NETP (ELE_NETP_LP); (2) elemental compositions of loess and paleosol deposits in the ZYC section on the NETP (ELE_NETP_ZYC); (3) elemental compositions of loess and paleosol deposits in the GC section on the NETP (ELE_NETP_GC); (4) elemental compositions of loess and paleosol deposits in the RS section on the NETP (ELE_NETP_RS). The dataset was archived in .xlsx format. This dataset can provide essential support for investigating the source area and paleoenvironmental significance of loess-paleosol deposits on the NETP.
