The Quaternary sediments in the Yarlung Tsangpo River Basin (YTRB) are widely distributed and rich in types. A detailed field geological survey was carried out on the Quaternary sediments in the whole YTRB, including 16 sub-basins. The survey covers Langkazi, Jiangzi, Kangma, Sakya, Razi, Zhongba, Saga, Angren, Xietongmen, Nanmulin, Jiacha, Bomi, Motuo County, Mozhugongka and its surrounding areas. The dataset records the work log, fieldwork photos, and geological profile photos of field geological investigation on different Quaternary sediments in the YTRB. 16 profiles and 40 remote sensing interpretation markers of loose sediments were investigated. It is of great significance to find out the temporal and spatial distribution and change mechanism of Quaternary sediments in YTRB for revealing the evolution of water system, monitoring and protection of plateau ecological environment, soil and water conservation, early warning and prevention of natural disasters, and construction of major infrastructure projects.

File naming and required software

File name: dataset is stored in PDF, xlsx and JPG formats, and the name of the document is "YTRB_QS_OS/RS". The name of the photo file is "YTRB_QS_FP_Qal_01"_. YTRB represents the Yarlung Tsangpo River Basin, QS represents the Quaternary sediments, OS represents the measured section, RS represents the remote sensing interpretation mark field sample points; FP represents the field photo, Qal represents the alluvium, and 01 represents the first photo of this type of sediments.
Data reading mode: PDF, xlsx format data can be opened and read by the Office, WPS and other office software, JPG format data can be read by windows photo viewer, Picasa photo viewer and other image viewers.
