<p>This data set was analyzed and completed by the Northwest Institute of Ecology, Environment and Resources, China Academy of Sciences. The data includes the grain size composition and TOC and TN content data of two typical geological profiles (NY-01 and LB-03 profiles) in the north and south of the Taklimakan Desert. The particle size analysis instrument is a Mastersizer 2000 laser particle size analysis instrument with a test range of 0.02-2000 μm;TOC and TN use potassium dichromate spectrophotometry and Kjeldahl nitrogen determination method. This data reflects the material composition and soil nutrient characteristics of geological sediments at different locations in the north and south of the Taklimakan Desert, and is of great significance for reconstructing past oases and deserts evolution. </p>
This data was obtained by collecting samples from two typical geological sections (NY-01 and LB-03 sections) in the north and south of the Taklimakan Desert with depth and measuring them using professional instruments.
Samples from LB-03 profile are sampled at 0.15m intervals, and samples from NY-01 are sampled at 0.1m intervals. The particle size analysis instrument of the table sample is a Mastersizer 2000 laser particle size analysis instrument, with a test range of 0.02-2000 μm;TOC and TN use potassium dichromate spectrophotometry and Kjeldahl nitrogen determination method.
The particle size of this data is in accordance with the national standards of People's Republic of China, particle size distribution laser diffraction method GB/T 19077-2016/ISO13320:2009;TOC is determined according to international standards ISO14235 -1998, GB/T5009.5-2010;TN is determined according to international standard ISO13878:1998. The data error is 0.01, and the data is qualified.
