摘要
本文利用扫描电镜,观察了调查区现代石英砂表面的微结构。研究结果表明,在亚热带海域中的石英颗粒表面化学溶蚀痕迹最为发育。
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 investiget-ed area was in littoral sedimentary environment in the past.
