  • This data includes sediment detrital mineral data and coarse component composition data. Detrital minerals are obtained from sediment in the 0.063-0.25 mm grain size fraction through water sieving method, and heavy liquid separation method is used to obtain light and heavy fractions, which are then identified as detrital minerals. Identified the components in the 0.25-2 mm size fraction. Utilize optical microscopes, including stereo microscopes and polarizing microscopes. The data was completed in 2024. Obtained coarse component and detrital mineral composition data since 12000 ka BP. The sample area is located on the Laptev Sea shelf. The purpose is to study the changes in paleo- climate and environment, understand the interactions between terrestrial fluvial input materials, permafrost, and island erosion materials during the process of sea level rise in the Siberian Arctic shelf region, as well as the sedimentation of the shelf.
