SURFACE MICROSTRUCTURE OF THE QUARTZ GRAINS IN THE SEDIMENT OF THE NORTH BEIBU GULF
Abstract:
Surface microstructure of quartz grains in the sediment of the North Beibu Gulf werestudied with the scanning electron microscope. Traces of chemical solution and mechanicalcrushing were found in the surface of quartz grains, which indicates that the investigeted area was in littoral sedimentary environment in the past.
Key words:  Quartz  Chemical solution traces  Sedimentary environment
