Comprehensive particle size database of surface sediments from different dune types in the Kubuqi Desert,China

It is a comprehensive particle size database of surface sediments from different dune types in the Kubuqi Desert, China41. It consists of 2 data files, Excel DATA 1 and DATA 2, describing the grain size characteristics of surface sediments of different types of dunes in the Kubuqi Desert.
DATA 1: Characterization of particle size parameters of surface sediments from dunes in the Kubuqi Desert and database of depositional environments. It specifically contains the following data fields: Sheet 1: Basic information about the sample collection, including where the sample was collected (latitude and longitude), when it was collected, and an explanation of the acronyms for the different dune types. Sheet 2: (1) the name of the sample site; (2) the type of dune in the area where the sample is located; (3) the grain size corresponding to the cumulative percentage of sediment (μm); (4) the grain size corresponding to the cumulative percentage of sediment (mm); (5) the grain size corresponding to the cumulative percentage of transformed sediment (φ); (6) the four grain size parameters of the sediment; (7) the depositional environment of the sediment. This file provides the basic sediment composition data of different dunes and does the discrimination of the depositional environment.
DATA 2: Database of particle size parameter characteristics and composition of surface sediments of different types of dunes in the Kubuqi Desert. This file is subdivided into seven groups according to the type of dune, named by the abbreviation of the name of the dune type, and specifically contains the following data fields: (1) the number of the sample; (2) the type of dune; (3) the particle size parameters, including the mean particle size, sorting, skewness, and kurtosis; and (4) the percentage of the composition of the components of the sample. These metrics provide a measure of the internal composition of different types of dunes and potential modes of sand transport.
