Surface textures of quartz grains from a core at the Prydz Bay, Antarctica |
| |
| Abstract: | In this paper, shapes and surface textures of quartz grains in 13 layers of a core (NP95 1) collected from a continental slope at the Antarctic Prydz Bay were quantitatively and statistically analyzed. The quartz grain surfaces exhibit the characteristics caused by intense glaciation and a weaker chemical solution precipitation, indicating the sediments are mainly morainic debris under a low energy marine environment. The obtained quantitatively statistical results of the assemblages of surface textures caused by the chemical solution precipitation are well correlated to the analytical results of micropaleontologic analysis and can be used to better explain the changes of sedimentary environment and paleoclimate occurred in the marine zone concerned. |
