| Abstract: | Quartz grain surface textures in coastal dune sand which is mainly derived from beach sand have features characteristic of both typical aeolian environment and inheritable and reformable beach sand. Situated in the South Asian subtropical and tropical monsoon climate region,the coast along Guangdong and Hainnan Provinces has a wet and hot climate in the summer half-year so that it is favorable to chemical action marks developing on the surface of coastal dune quartz sand grains; but the coast has a dry climate dominared by the northeast monsoon winds and with strong wind-drift sand activity in the winter half-year,which causes lots of mechanical strike marks to occur on the grain surface. |
