雅鲁藏布江流域沉积物理化指标和典型景观、地貌、沉积照片（2019.07-2019.08）

数据为2019年7月-8月专题组在雅江下游河谷、尼洋河流域获取的典型景观、地貌和沉积地层照片，以及黄土、河流沉积物的理化指标，主要包括：（1）尼洋河下游14C样品采样及年代；（2）尼洋河下游OSL年代学结果；（3）尼洋河下游喇嘛湾湖相沉积物与浪欧黄土XRF；（4）尼洋河下游喇嘛湾湖相沉积物与浪欧黄土磁化率 ；（5）尼洋河下游浪欧黄土粒度；（6）雅鲁藏布江下游河谷和尼洋河流域元素。照片主要展示了冰川、河流、湖泊等景观，以及滑坡面、冰川剪切面、沉积相等。

The dataset comprises typical landscape, geomorphology and sedimentary stratigraphy photographs, as well as physical and chemical indicators of loess and fluvial sediments, collected by the research team in the lower Yarlung Zangbo River Valley and Niyang River Basin during July to August 2019. The dataset primarily includes:
1. Sampling and chronological data of ¹⁴C samples in the lower reaches of the Niyang River;
2. Optically Stimulated Luminescence (OSL) chronological results for the lower Niyang River;
3. XRF data of lacustrine sediments from Lamawan and loess deposits from Lang'ou in the lower Niyang River;
4. Magnetic susceptibility data of lacustrine sediments from Lamawan and loess deposits from Lang'ou in the lower Niyang River;
5. Grain size data of Lang'ou loess in the lower Niyang River;
6. Elemental composition data for the lower Yarlung Zangbo River Valley and Niyang River Basin.
The photographs mainly showcase landscapes such as glaciers, rivers and lakes, as well as landslide surfaces, glacial shear planes, sedimentary facies and other related features.
