Abstract

Sediment granularity and surface microtextural characteristics are important indicators that reflect the sedimentary environment and source area. Based on particle size analysis and scanning electron microscopy imaging, the granularity parameter and microtextural characteristics of coastal aeolian sediments in the Daling section of the coastal Donghai Island in Guangdong Province were studied to reveal their sedimentary environment and sedimentary processes. The results show that: (1) The granularity characteristics of Daling section are typical of eolian sand. (2) The quartz particles in Daling section have moderate roundness, and the surface is characterized by pockmarks/pits, dished pits, crescent-shaped impact pits, underwater polished surfaces, scaly peeling, etc. The quartz particles in Daling section are firstly abraded and transported by water, and then secondarily transported and reformed by wind. The characteristics of wind action are remarkable. (3) The Daling section records the evolution history from warm and humid environment to cold and arid environment.
